5 GHz Bow-tie-shaped Meander Slot Antenna

다국어 초록 (Multilingual Abstract)

In this paper, we propose a bow-tie-shaped meander slot antenna fed by a microstrip line to achieve compact size as well as wideband characteristic. While conventional bow-tie slot antennas exhibit wide band characteristic, they have relatively large. On the other hand, the meander slot antennas are very small, but they reveal quite narrow bandwidth (typically less than 1%). To realize miniaturized antennas having large bandwidth, combination of the bow-tie slot and the meander slot geometries is proposed in the paper. Theoretical results show that the proposed antenna with uniform slot width is 65.5% smaller than that of the conventional bow-tie antenna in size, while the bandwidth is 3 times larger than that of the meander slot antenna. Moreover, the non-uniform slot width antenna shows 60% smaller in size and about 3.5 times wider in bandwidth than the previous antennas. Measured antenna performance reveals excellent agreement with the predicted values.
