This paper describes innovative antenna feed development at MDA. The work addresses the need for high-performance dual-circular-polarized payloads for next-generation L and S-band mobile satellite communications. The mechanical design concept is presented, including dimensions and mass, along with the RF analyses and test measurements for a septet feed array of “cup-horns” with two coaxial diplexers. An alternative waveguide diplexer solution is also presented.
