This paper presents a narrow-beam sub-THz classical offset Cassegrain antenna for communication links with multi-Gbps throughput. To the best of the authors' knowledge, this is the first demonstration of truly far-field measured offset dual-reflector lightweight antenna having a half-power beam width of …

This paper presents a comparison of two kinds of waveguide polarizers for use in Ka-band Gyro-TWT. It is shown that in competition versus conventional polarizer having rectangular corrugation, a sine-corrugation is not necessarily a prerequisite for superior high-power handling or enhanced circular …
