Abstract

An electrically small antenna (ESA) with broadside and monopole-like beam reconfigurability is presented. It consists of an electric monopole radiator and a magnetic radiator which are systematically placed orthogonal to the ground. By controlling the PIN diodes integrated into the feed structure, broadside and monopole-like beams can be switched dynamically. The broadside beam is generated by the capacitively loaded loop (CLL) near-field resonant parasitic (NFRP) element and the monopole-like beam is formed by the electric monopole. The simulated results indicate that the antenna is impedance matched within an overlapping operational fractional bandwidth of 2.5% even though it is electrically small with ka=0.69. The realized gain value at boresight is 7.1 dBi for the broadside beam and the null depth is over -30 dBi for the monopole-like beam, respectively. The proposed antenna is ideal for application to GPS systems that require anti-interference performance characteristics.
