A compact design for a single‐feed cavity‐backed slot antenna is presented for operating at GSM (900 MHz) and DCS (1800 MHz). With the use of a carefully designed power distribution network, a single‐feed design is realized for a dual‐ and wideband slot antenna with high gain and good radiation patterns. Measured results show that the antenna has a wide bandwidth at both frequency bands and it exhibits high gain and good radiation patterns, which is desirable for many dualband applications.© 2007 Wiley Periodicals, Inc.
