A compact reconfigurable antenna with pattern diversity

• A compact pattern reconfigurable antenna is proposed, in which the beam pattern can be switched between a monopole like radiation and a broadside radiation. Two layers and three PIN diodes are employed in the antenna. A single coaxial feed is utilized to excite both monopole mode and PIFA mode at a center frequency of 2.62 GHz. The total efficiencies of the antenna are 72% and 95% for monopole and PIFA modes, respectively. The envelope correlation coefficient calculated from the two patterns is 0.28, indicating good diversity performance of the antenna in wireless communications.
