摘要

本文提出了一种适用于现代无线应用的宽阻抗贴片电子可操纵寄生阵列辐射器(ESPAR)的介电谐振器。通过在贴片谐振器的顶部采用介电谐振器作为ESPAR阵列的紧凑组成辐射元件，实现了阻抗带宽的增强。在15ghz频率下实现了一种3元交换波束ESPAR阵列。开关是基于pin二极管的。实现的阻抗带宽超过24%，与文献中基于DR的espar相比，这是最宽的。该天线在0°，+25°和- 25°方向上实现波束转向，最大增益为8.26 dBi。给出了全波模拟。

Wideband Multibeam-Electronically Steerable Parasitic Array Radiator (ESPAR) for 5G Applications

This work presents a dielectric resonator on patch-electronically steerable parasitic array radiator (ESPAR) with wide impedance bandwidth for modern wireless applications. Enhancement of impedance bandwidth has been achieved by employing dielectric resonator on top of patch resonator as a compact constituent radiating element of the ESPAR array. A 3-element switched beam ESPAR array has been implemented at 15 GHz. Switching is based on PIN-diodes. The achieved impedance bandwidth is more than 24% which is the widest in comparison to DR based ESPARs in the literature. The antenna achieves beam steering in 0°, +25° and −25° directions with maximum gain of 8.26 dBi. Full wave simulations have been presented.
