Abstract

A bow-tie-shaped meander slot antenna fed by a microstrip line is proposed for 5 GHz applications. A conventional bow-tie slot antenna has a broad bandwidth; however, it is relatively large, and is thus inappropriate for miniaturized communication systems. Meanwhile, the meander slot antenna has small size, but its bandwidth is quite narrow. To realize miniaturized antennas having large bandwidth, we combine the bow-tie slot and meander slot geometries heuristically. Simulation results, confirmed by measured data, show that, for antennas designed to operate at 5.25 GHz, the proposed antenna is 65.5% smaller in size than the bow-tie antenna and the bandwidth is 3 times larger than that of the meander slot antenna.
