Abstract

The performance of a V‐slotted microstrip patch antenna, with and without additional edge slots, is investigated. It is shown that the V‐slotted patch is broadband, but its cross polarization increases with frequency. Placing two additional rectangular slots at the patch edges, parallel to its shorter side, eliminates the problem without affecting the bandwidth. The cross‐polarization becomes independent of frequency. It remains low over a bandwidth, which is wider than the antenna‐impedance bandwidth. © 2004 Wiley Periodicals, Inc.

## Abstract In this article, a new slot antenna with a quasi‐spiral slot is proposed.A simple microstrip line feed is used to excite the slot antenna. Measurement results show that 10 dB return loss bandwidth and 3 dB axial ratio bandwidth of the proposed antenna are 87 and 43%, respectively. © 201

Two wideband tapered slot antennas are designed, fabricated, and tested. The first antenna, which is fabricated on a high dielectric constant substrate (e r 5 10.2), shows a measured return loss of better than 10 dB from 1.6 to 12.4 GHz (7.7:1 bandwidth), and an antenna gain varying from 3.6 to 7.8
