Abstract

A full ground plane dual band microstrip antenna (FGP-DBMA) over ISM and HiperLAN/2 applications is presented. The structural design of the FGP-DBMA is based on suspended plate antenna. The FGP-DBMA antenna features a 56 × 55 mm2 rectangular radiating element suspended over 90 × 90 mm2 ground plane. ShieldIt Super conductive textile features are used as the radiating element and ground plane while felt textile features are used as the dielectric substrate. The rectangular radiator patch is designed using slits for dual-band resonance over ISM band (2.4 GHz to 2.48 GHz) and HiperLAN/2 band (5.725 GHz to 5.875 GHz). The FGP-DBMA radiates unidirectional with a fully grounded plane to avoid coupling onto user's body. The FGP-DBMA shows efficiency over the range of 69.6 % to 75.6 % and gain over the range of 6.052 dB to 6.323 dB in the free space scenario. The evaluation of FGP-DBMA with bending effects shows no significant changes to the performance of the FGP-DBMA. This indicates that the curvature effect on the proposed FGP-DBMA for on-body performance, i.e. on human arm, does not affect the performance of the antenna.

用于ISM和HiperLAN/2应用的全地平面双带微带天线

提出了一种适用于ISM和HiperLAN/2的全地平面双频微带天线(FGP-DBMA)。FGP-DBMA的结构设计基于悬板天线。FGP-DBMA天线具有一个56 × 55 mm2的矩形辐射元件，悬浮在90 × 90 mm2的接平面上。采用超导织物特征作为辐射元件和接地面，采用毛毡织物特征作为介电基底。矩形辐射片采用狭缝设计，在ISM频段(2.4 GHz ~ 2.48 GHz)和HiperLAN/2频段(5.725 GHz ~ 5.875 GHz)上实现双频谐振。FGP-DBMA采用全接地平面单向辐射，避免耦合到用户身体上。在空闲空间情况下，FGP-DBMA的效率在69.6%至75.6%之间，增益在6.052 dB至6.323 dB之间。具有弯曲效应的FGP-DBMA的评估结果表明，FGP-DBMA的性能没有明显变化。这表明，曲率效应对所提出的FGP-DBMA的身体性能，即在人的手臂上，不影响天线的性能。
