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. © 2010 Wiley Periodicals, Inc.
