In this paper, a wideband circularly-polarized patch antenna is presented. The patch is fed by four probes arranged by sequential rotation arrays, the four probes are connected to a feed network comprising of a pair of broadband 90° phase shifter and Wilkinson power divider. The proposed antenna shows a compact low profile, wide axial-ratio (AR) bandwidth, wide reflection coefficient bandwidth, as...
A technique is developed in this letter to enhance the impedance and axial-ratio (AR) bandwidths as well as broadside gain of a sequential phase (SP) feed 2 2 patch array. The proposed antenna is composed of a probe-fed patch, a 22 corner truncated patch array with a loop, and a slotted metal wall surrounding the feeding structure. The proposed antenna combines the attractive features...
