A multiband printed monopole antenna is presented, operating primarily in the 900 MHz, 2.4 GHz bands, and 5 GHz bands. A coplanar waveguide feed arrangement is deployed, simplifying the antenna structure to a single side of a printed substrate material. Despite the small size of the antenna, a lower‐edge frequency of 650 MHz is achieved. An impedance bandwidth of 63% is achieved in the 2.4‐GHz band. The low profile antenna presented is potentially suitable for applications in modern mobile and portable radio systems that require operation over widely separated bands, combining multi‐band operation with small size and low profile. With the application of a shorting post, the antenna has the potential for reconfigurable applications. © 2006 Wiley Periodicals, Inc.
