Planar Bowtie Antenna with a Reconfigurable Radiation Pattern

This paper presents a novel planar antenna with a reconfigurable radiation pattern. The proposed layout consists of N ≥ 2 monospaced planar bowtie antennas selected one by one by means of a pair of PIN diodes. Experimental results referring to the case of N=2 and N=4 are reported and discussed demonstrating the feasibility and effectiveness of the proposed design approach.
