5GHz 대역 무선 LAN 송수신 시스템 설계 및 구현

In this paper, a meander-type microstrip patch antenna for application in 5GHz-band is designed and fabricated. To obtain enough bandwidth in VSWR<2, the foam is inserted between substrate and ground plane, the coaxial probe source is used. Antenna is simulated varing the length and width of meander line, the position of probe feeding and the thick of airgap. Later antenna is fabricated with optimizated antenna parameter. The measured result of Fabricated antenna obtained 1GHz(17.5%) bandwidth in VSWR<2, the gain of 7.3∼9.5dBi, Unidirectional pattern.
