CubeSats and SmallSats have resulted in tremendous amounts of excitement within research, industry and defense communities. They are responsible for a remarkable revolution in the arena of satellites for diverse applications. Their small size and low cost have enabled space missions which seemed impossible with the conventional satellites. To further enhance the potential of CubeSats and SmallSats ingenious antenna developments play paramount roles in meeting the demanding data-rate and spatial resolution requirements for future missions. To achieve these objectives tradeoff between mechanical complexity and RF performance are resulting into amazing opportunities for antenna engineers to be innovative. Many of the earlier missions have utilized low-gain antennas due to their ease of mechanical integration; however, emerging CubeSats and SmallSats missions require high-gain antennas that can be stored in a small volume during launch and deploy reliably in space. This plenary talk highlights the challenges and opportunities that CubeSats and SmallSats create for antenna engineers. Notably emphasis will be on some out-of-the-box concepts that have been recently developed to facilitate advanced space missions. The talk will focus on the design of deployable high gain aperture antennas that can meet the demands of remote sensing, deep space missions and Internet of Space (IoS) with particular importance to the design tradeoffs based on some ingenious concepts relying on mesh deployable reflector antennas, reflectarray antenna, 3-D printed lens antennas and others. With the outlooks of affordable space missions and global connectivity becoming a reality, we must look forward to many more developments in the field of antenna engineering tailored for CubeSats and SmallSats. Some representative papers published by the speaker are listed below for the interested readers.

Wireless communication sensors and devices must operate efficiently in a heavily trafficked radio propagation channel. The internet of things projected to have upward of one trillion sensors. This explosion of wireless sensor and communication devices demands that communication engineers rely heavily on knowledge of the radio propagation channel’s statistical variation to enable for effective spectrum sharing. The ability to capture the statistical variation of the propagation channels falls onto the capabilities of channel sounding and rigorous and concise measurement and modeling science.
Poor performing channel sounder’s hardware leads to errors in the channel measurements. Signals passing through real hardware components, introduce distortion at every step of the process, from signal generation and transmission to signal reception and demodulation. This distortion degrades the channel measurements.
Stemming this tide of errors is measurement best practices. Obtaining robust and accurate measurements involves verifying the channel sounder’s hardware and data post-processing with thorough documentation of the measurement campaign. Channel-sounder verification involves rigorous measurement practices and statistical models to identify sources of the components of uncertainty in a channel sounder’s measurements. Knowledge of these sources enables the separation of measurement uncertainty from the channel variations, allowing for accurate measurement of the channel. Consequently, measurement best practices for verification of the channel-sounder hardware and post-processing is a fundamental building block for wireless communication sensors and devices efficiently use of the spectrum.
