L形プローブを用いた広帯域広角円偏波導波管アンテナ

抄録

A broadband and circularly polarized waveguide antenna is presented. In this structure, an L-shaped probe is used to feed the antenna. In addition to this, the waveguide has a short wall with a parabolic shape, and the aperture area is also reduce. With these ideas, this antenna has a wideband impedance and axial ratio characteristics of 40% and a wide angle range for circular polarization radiation in the radiation pattern with low cross-polarization.
