Abstract
A vertically polarized, low-profile, compact, near-field resonant parasitic (NFRP) antenna with pattern-reconfigurability is demonstrated. The antenna has three dynamic end-fire states facilitated with only three p-i-n (PIN) diodes. The radiation pattern in each state covers more than 120° in its azimuth plane and, hence, it achieves beam-scanning that covers the entire azimuth plane. The antenna height and transverse size are, respectively, only 0.048 λ0 and 0.1 λ02. Measured results, in good agreement with their simulated values, demonstrate that the antenna exhibits a ~11% fractional impedance bandwidth and a ~6.6 dBi peak realized gain in all three of its pattern-reconfigurable states. Stable and high peak realized gain values are realized over its entire operational band surrounding 2.22 GHz.
