DIELECTRIC-RESONATOR-LOADED MICROSTRIP ANTENNA FOR ENHANCED IMPEDANCE BANDWIDTH AND EFFICIENCY
暂无分享,去创建一个
A new method for enhancing the 2.1 VSWR impedance bandwidth of microstrip antenna s is presented. Bandwidth enhancement is achieved by loading the microstrip antenna by a ceramic microwave dielectric resonator (DR). The validity of this technique has been estab- lished using rectangular and circular radiating geometries. This method improves the bandwidth of a rectangular microstrip antenna to more than 10% (= 5 times that of a conventional rectangular microstrip antenna ) with an enhanced gain of I dB. © 1998 John Wiley & Sons, Inc.
