Abstract
In this paper, to improve bandwidth of microstrip antenna, we discussed the patch structure using dual patch and probe feed. To provide PCS service and IMT-2000 service simultaneous, a microstrip patch antenna needs impedance bandwidth of 22%. We propose wide-band microstrip path antenna without complexity. To analyze characteristics of microstrip patch antenna, we used Ensemble of commercial software. The microstrip patch antenna was designed, fabricated, and tuned. The result was that 500 ㎒(25.5%) of impedance bandwidth for VSWR 2,430 ㎒(21.9%) of impedance bandwidth for VSWR 1.5. The microstrip patch antenna has side lobe of -14 dB. The front to back ratio is 20 dB overall. The measured gain of the microstrip patch antenna is 5.2 dBi.
