“…As is shown in Fig. 7(b), a large extended copper ground plate was employed in the measurements to accurately evaluate its vertical polarization performance [3], [4], [6], [7], [14], [19]. The measured results together with their simulated values in each pattern state are presented in Fig.…”

“…Consequently, they have been widely applied in a variety of wireless systems. Examples include fifth-generation (5G) wireless communications devices [1], on-body communication systems [2], avionics applications [3], radar platforms [4], and customer-premises equipment (CPE) applications [5].…”

“…The existing techniques in extensive use can be generally classified into three categories. The first includes the integration of switchable ON/OFF devices such as p-i-n (PIN) [1], [2], [6]- [9] and varactor [4], [10]- [14] diodes. The second encompasses the introduction of switch networks such as controllable reactance circuits [15]- [16], beamforming networks [5], and control circuits [17]- [19].…”

“…The third resorts to mechanically controlled devices, e.g., movable liquid metals such as mercury [20] and electric motors to rotate the radiators [21]. While effective, these reconfigurable design schemes [1]- [4], [6]- [19] all consist of one central driven element and multiple parasitic elements around it. When operating in a single state, these reconfigurable systems only have a certain number of their parasitic elements active while the rest of them are idle.…”

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-in (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 λ 0 and 0.1 λ 0 2. 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.

“…Scott and Fusco [2] studied a circular array with the driven element in the center and 24 other elements uniformly dispersed along two concentric rings around the driven element. Each of these non-driven elements is reactively loaded so that their electrical length can be modified and this in turn directs the beam.…”
