摘要

提出了一种适用于WLAN频段的新型双频介质谐振器天线。DRA由附在DRA上的垂直带激发，该垂直带连接到有缺陷地平面上的50 Ω微带线。变形的接平面在DRA下有导电带，引起2.4 GHz的第一次共振。由于介质谐振器和垂直条形激励，第二波段在5 ~ 8 GHz之间有44%的带宽。

Dual band dielectric resonator antenna mounted on a defected ground plane

A new dual band dielectric resonator antenna (DRA) for WLAN band is presented. The DRA is excited by a vertical strip attached to the DRA, which is connected to a 50 Ω microstrip line on a defected ground plane. The deformed ground plane has a conducting strip under the DRA that cause the first resonance at 2.4 GHz. The second band is wide with 44% bandwidth between 5 to 8 GHz due to the dielectric resonator and the vertical strip excitation.
