© 2022 IEEE.In this work, a pattern reconfigurable antenna with improved pattern diversity is proposed. The antenna is formed by placing a circular ring around a circular microstrip patch antenna and excited by using two feeds. The in-phase and out-of-phase excitation of these feeds provides conical beam and broadside radiation, respectively. Slots are introduced to the ground plane of the antenna to steer the main radiation direction in broadside radiation mode and to obtain asymmetric radiation in conical beam mode. Consequently, the pattern diversity of the two-mode antenna is improved.
