''Advanced Antenna Designs for Space, Air & Ground Communications: An Industry Perspective''
Abstract:
Antennas are “Eyes and Ears” of modern-day communication systems. They are key components of any communications link providing the coverage, gain to close the communication link, bandwidth, capacity/data rates and polarization. Antenna engineering is a highly specialized skill in the industry and the role of antenna engineer is to develop appropriate products and qualify them for any intended application. Antenna has to meet several requirements simultaneously and often times the design becomes a difficult task for engineers. Simple designs are elegant designs! Antenna designs could be simplified even with complex requirements if the fundamentals are well understood. This talk will cover antenna applications, various types of antennas, fundamentals, and design methodologies for reflector antennas, omni-antennas, UWB antennas and phased array antennas. Antenna hardware for satellites, aircrafts, vehicles and ground communication systems will be discussed. Industry perspective of developing antenna products for different applications is emphasized.

''Antenna Designs Shaping the Future of Space Exploration'
Abstract:
In this presentation, we will delve into recent advancements in the field of antenna design and propagation modeling, with a specific focus on their crucial role in Space Exploration. Our exploration will be richly illustrated through a spectrum of successful NASA missions.
A notable achievement from NASA’s Jet Propulsion Laboratory is Mars Ingenuity, the first-ever Mars helicopter. Enabling seamless data transmission to and from a Mars Rover situated up to 1 kilometer away, this groundbreaking technology relies on intricate antenna designs and propagation techniques tailored for the Martian landscape. Meticulously executed flights have provided valuable data for rigorous assessments, encompassing factors such as shadowing effects, multipath scenarios, polarization loss, and signal fading, demanding precision in modeling both the Mars Rover and the helicopter.
In the second part of our presentation, we will delve into the forefront of antenna innovations tailored for Cubesats, Rovers, and Landers. NASA’s Jet Propulsion Laboratory has been instrumental in driving the rapid evolution of CubeSat antennas, introducing cutting-edge deployable designs across X- and Ka-band frequencies. A notable illustration of these advancements is the Mars CubeSat One (MarCO), featuring a deployable X-band reflectarray that played a vital role in transmitting critical data back to Earth during the Entry Descent and Landing (EDL) phase of NASA’s Insight mission. Our exploration will further uncover the remarkable strides made in the development of a Ka-band mesh reflector for the Raincube mission, distinguishing itself as the world’s inaugural active radar-equipped CubeSat. Post-deployment in orbit, Raincube has meticulously gathered valuable rain precipitation data globally for an impressive two-year duration. Concluding this segment, we will shed light on the Europa Lander mission concept, where a highly efficient high-gain antenna takes center stage, showcasing its resilience in withstanding the extreme cryogenic and high radiation conditions characteristic of Europa’s surface. We will also discuss recent progress on UAV snow radar, radiometer for fire detection, and other innovative concepts.
In a realm where innovation presents formidable challenges, this presentation underscores how creativity has been the driving force behind pioneering missions, unlocking new frontiers, and reshaping the landscape of space exploration.

''Antenna Systems for Space Applications at NASA Jet Propulsion Laboratory''
Abstract:
Antenna developments for space applications has a long history at NASA Jet Propulsion Laboratory. Starting from the 70’s, Voyager, Galileo, Cassini, SRTM and more recently Aquarius, SMAP, SWOT, NISAR and INCUS are just a few major flight projects that required the design and development of very complex antenna systems for telecom, radar and radiometric applications. They were, and in most cases still are, the state of the art in antenna design for space applications. In the past we mostly relied on relatively simple RF models and formulations and did a considerable amount of prototype testing to validate antenna performance. In recent years RF modeling tools like HFSSTM, GRASPTM and a few more, have reached capabilities that were unimaginable just a few years back. At the same time, computer power and available memory have been increasing steadily. Thanks to this fertile ground it’s now possible to run extremely complex RF simulations of very large structures in a relatively short time with very good results. This presentation will guide the audience through a few examples of flight projects where very complex RF models have provided extremely accurate results and allowed the development of very complex instruments, some of which are still flying today.

"Deployable Antenna Mechanism and Structural Design: Design Principles and Lessons Learned"
Abstract:
Deployable antennas play a key role in modern space missions, enabling Earth and planetary science measurements and long-distance communications to be conducted from smaller platforms with larger footprints or greater gain. Deployable antennas present unique structural and mechanism design challenges. The goal of this presentation will be to education non-mechanical engineers on key principles related to deployable mechanism and structural design, to aid them in creating robust concepts. This will also enable them to understand key terms to better communicate with mechanical engineers and also ask informed questions about the design. A summary of the principles to be shared included:
- Reduce the Number of Deployments: the best solution is to avoid a deployable if possible.
- Prioritize Repeatable and Deterministic Systems: Opt for systems that demonstrate repeatability and determinism during testing under various conditions to detect failures early.
- Leverage Rotation to Reduce Friction: Prefer rotation over linear sliding to minimize friction and exploit moment arm effects.
- Maximize Depth from Rotation Axis: Utilize as much depth from the rotation axis as possible to maximize the moment arm advantage and to increase structural stiffness.
- Maintain Sliding Length-to-Diameter Ratio Above 2: When linear sliding is unavoidable, ensure the ratio of the length of the device sliding to its diameter remains greater than two at all times (L/D > 2).
In conclusion, the dissemination of these principles aims to equip non-mechanical engineers with valuable insights, enabling them to collaborate better and create sound preliminary architectures when deployable antennas systems are required.

"RF Design of Wideband mmWave Beamforming Systems"
Abstract:
The current trend for wireless systems to operate at millimetre wave (mmWave) frequencies and over wide bandwidth drives challenging requirements for RF front ends. In this workshop, you will learn how MATLAB and Simulink can be used for modelling RF and mmWave transceivers, performing RF budget analysis, and simulating wideband adaptive architectures. These will include RF components such as amplifiers, matching networks, and antenna arrays operating at mmWave frequencies. Using virtual prototypes, we will simulate wideband transmitter and receiver behaviour including coexistence and interference scenarios along with beam-squinting and antenna coupling. These same virtual prototypes will be used to perform dynamic EVM measurements for different communications standards such as 5G FR2. With practical examples, we will demonstrate how to optimize baseband signal processing compensate for RF impairments, improve overall receiver sensitivity in the presence of interfering signals, and to support multiple communication standards.
