Abstract

A novel composite monopole antenna suitable for 2.4/5.2/5.8‐GHz wireless local area network (WLAN) and 2.5/3.5/5‐GHz worldwide interoperability for microwave access (WiMAX) operation is presented. The composite monopole antenna comprises a ceramic chip radiating element as arm 1 of the antenna and a printed radiating element as arms 2 and 3 of the antenna. The three arms effectively control three excited wide resonant modes for WLAN/WiMAX operation, and the total area occupies by the composite monopole antenna is 8 × 19.5 mm^2^ only, which is much smaller than that of a corresponding printed monopole antenna. Due to the compact area occupied, the proposed antenna is promising to be embedded within the narrow spacing between the casing of the laptop computer and the supporting metal frame of the display as an internal antenna. © 2006 Wiley Periodicals, Inc.
