In this article, the design of a radiation beam-reconfigurable antenna using the reflector pins is presented. The reflector pins make a short or open connection with the ground, via switches and Plated Through Hole (PTH), which helps in controlling radiation characteristics of the proposed antenna. This design contains a simple 3D printed Cylindrical Dielectric Resonator Antenna that is located at the center of the substrate. The beam-sweeping of the antenna is attained by operating switches in different combinations of ON and OFF states. The reconfigurable CDRA operates at 4.5 GHz and covers all azimuth angles in four steps with a maximum measured gain of 6.6 dBi. This beam-switching antenna is very advantageous because of its trait of eliminating fade zones and beamforming.

3-D打印CDRA，用于C波段的辐射束可重构性和波束形成

在本文中，介绍了使用反射器针脚的可重新配置辐射束的天线的设计。反射器引脚通过开关和镀通孔（PTH）与地面形成短路或开路连接，这有助于控制所建议天线的辐射特性。该设计包含位于基板中心的简单3D打印圆柱介电谐振天线。天线的波束扫描是通过以ON和OFF状态的不同组合操作开关来实现的。可重新配置的CDRA以4.5 GHz的频率运行，并以四个步骤覆盖所有方位角，最大测量增益为6.6 dBi。该波束切换天线由于消除了衰落区和波束成形的特性而非常具有优势。
