초록

Printed microstrip antennas are known to have limitations in terms of bandwidth by the presence of the dielectric substrate. In this paper, to overcome these limitations, a broadband microstrip bow-tie antenna which has two dip point for high speed wireless LAN, fabricated on a Taconic substrate is designed and simulated. In simualted results, the return loss is two dip point which is -28.5dB at 5.68GHz and -27dB at 5.85GHz. The bandwidth of this antenna is 8.7％ about VSWR$\leq$2 and 5.9％ about VSWR$\leq$1.5.
