Design of Triple Band Microstrip Yagi Uda Antenna

Abstract

Abstract

     A microstrip yagi uda antenna with triple band is proposed in this paper. The design antenna consists of CPW feeding in which the ground plane and the yagi antenna are on the same plane. The resonating frequency of design antenna is 6.29, 7.97 and 9.26 GHz. The antenna had achieved the directivity of 5.232, 5.704 and 6.062 dBi.  The impedance of antenna is completely matched at all the three resonating frequency. The triple band microstrip yagi uda antenna was simulated by Computer simulation technique (CST) MW studio software.
