Abstract

GPS(Global Positioning System) is widely used in the navigation system, ITS(Intelligence Transportation System), and mobile communications. Recently, it is considered to combine the GPS receiver with the CLONASS for the improvement of performance and accuracy. In this paper, a wideband aperture-coupled patch antenna with circular polarization is designed and implemented for the use of CPS/GLONASS combined receiver. The measured characteristics of the manufactured antenna shows the - l5 dB bandwidth of 220 MHz and the axial ratio less than 2.1 dB, and it satisfies the requirements of the GPS/GLONASS antenna.

GPS(Global Positioning System)는 항행, ITS(Intelligence Transportation System), 이동통신 등에서 널리 이용되고 있으며, 최근에는 GPS와 GLONASS 통합 수신기에서 사용할 수 있도록 광대역 원편파 특성을 나타내는 개구면 결합 패치안테나를 설계, 제작하였다. 제작된 -15dB 대역폭이 220 MHz, 축비 2.1dB이하로서 GPS 및 GLONASS 신호를 동시에 수신하기 위한 안테나의 특성을 만족하였다.
