A broadband and wide-beamwidth dual circularly polarized (CP) antenna is presented in this paper. The antenna consists of two bent dipoles placed in a crossed shape. The dipoles are individually fed with signals with quadrature phases from a 3-dB hybrid coupler chip. A metal cavity serving as a reflector is used to produce a unidirectional radiation pattern… CONTINUE READING
