Abstract: A single-feed reconfigurable square-ring patch antenna with pattern diversity is presented. The antenna structure has four shorting
walls placed respectively at each edge of the square-ring patch, in which two shorting walls are directly connected to the patch and the others are
connected to the patch via pin diodes. By controlling the states of the pin diodes, the antenna can be operated at two different modes: monopolar
plat-patch and normal patch modes; moreover, the 10 dB impedance bandwidths of the two modes are overlapped. Consequently, the proposed
antenna allows its radiation pattern to be switched electrically between conical and broadside radiations at a fixed frequency. Detailed design
considerations of the proposed antenna are described. Experimental and simulated results are also shown and discussed.
