본 논문은 PCS (1750 - 1850 MHz) 대역과 IMT-2000 (1920 - 2170 MHz) 대역의 이중대역(Dual-Band) 주파수(420 MHz)를 동시에 만족시킬수 있는 안테나로서 “L” 형태의 급전구조를 이용하여 안테나를 제작하였다. 제작된 안테나의 대역폭은 중심주파수(1.96 GHz)의 33%(VSWR < 1.5, 650 MHz)로 광대역 특성을 갖고, 이득은 7dB 이상의 양호한 특성을 얻었다.
Abstract
In this paper, the wideband microstrip patch antennas for the Personal communications Service (PCS : 1750~1870 MHz) and International Mobile Telecommunications-2000 (IMT-2000 : 1920~ 2170 MHz) dual band are studied. Experimental and simulation results on the dual band antenna are presented. Simulation results are in good agreement with measurements. The experimental and simulation results confirm the wideband characteristics of the antenna. The studied antenna satisfied the wideband characteristics that are required characteristics for above 420 MHz impedance bandwidth for the PCS and IMT-2000 dual band antenna. In this paper, through the designing of a dual band antenna, we have presented the availability for PCS & IMT-2000 base station antenna. An impedance bandwidth of 33% (VSWR<1.5, 650 MHz) and a maximum gain of 7dB can be achieved. The radiation pattern is stable across the passband.
