초록

There are many researches to increase bandwidth of the microstrip patch antenna for wireless LAN. In spite of broad bandwidth, Bow-Tie microstrip patch antenna, broadband microstrip patch antenna, has disadvantages that are low gain and big size. In this paper, stacked Bow-Tie microstrip patch antenna for wireless LAN is designed in 5.725∼5.825㎓ band. This antenna has characteristics that are broadband bandwidth, high gain and small size compared with microstrip patch antenna. In simulated results, the return loss is -34.2㏈ at 5.78㎓ and bandwidth is 11.345% for VSWR 2：1 and 7.75% for VSWR 1.5：1. In measured results, the return loss is -38.45㏈ at 5.78㎓ and bandwidth is 13% for VSWR 2：1 and 5.6% for VSWR 1.5：1. It has 59.37$^{\circ}$-3㏈ beam width and 6.5㏈ gain.
