and then the radiation performance of the conical die single-arm spiral antenna is changed, so that a slant beam with the fixed angle is generated, the gain of the antenna at the low pitch angle is improved, it is ensured that the antenna has the good circular polarization performance at ...
In this paper, a single-arm Archimedean spiral (SAAS) antenna with broadband circular polarization is investigated. Unlike traditional single-arm Archimedean spiral antenna, the antenna arm consists of a hybrid meandered strip line and a smooth arc strip line. Especially at low frequencies, the ...
