In the SATCOM (satellite communication) On the Move system, the polarization angle is not stability, which is easily affected by the carrier. To solve the problem, a new calculation formula for the compensation of polarization angle is deduced accord

This paper presents a novel dual-band helix antenna operating at HBC band. Two helixes are adopted to excite two resonances. One helix is fed by 50Ω port. The other one is excited by a short pin. The bandwidth of the proposed antenna covers 18.5-19.
