摘要

提出了一种进一步减小先前报道的紧凑型孔径耦合和腔背混合介质谐振器天线(hDRA)尺寸的概念。该概念提出使用由高阻抗人工表面制成的后平面来取代天线后腔，从而使天线高度增加约24毫米。人造表面背面由相互缠绕的平面四边形螺旋组成，形成紧凑的电磁带隙结构(EBG)，提供约35%的带隙。背板由两个单面印刷电路板(PCB)层组成。这样的后平面使天线整体高度降低了约21毫米。

Aperture coupled hybrid dielectric resonator antenna with an EBG back plane

A concept for further size reduction of a previously reported compact aperture coupled and cavity-backed hybrid Dielectric Resonator Antenna (hDRA) is presented. The concept proposes use of a back plane made of a high impedance artificial surface to replace the antenna back cavity, which adds about 24 mm to the antenna height. The artificial surface back plane is made of entwining planar quadrifilar spirals that form a compact electromagnetic bandgap structure (EBG) providing a bandgap of about 35%. The back plane is formed of two single sided printed circuit board (PCB) layers. Such back plane reduces the overall antenna height by approximately 21 mm.
