This paper experimentally presents a low‐profile broadband post‐type monopole antenna. The characteristics of the antenna are highly dependent on the design parameters ( R m , h m , h fl , and R g ). Instead of a wire monopole, the proposed antenna is made of a 16‐mm‐diameter aluminum post that is ceiling‐mounted in a building. This is due to the low‐radiation resistance in the usable band. The post‐type element is used to enhance the impedance matching. The experimental impedance bandwidth obtained is approximately 67.9% (1.9824–3.5534 GHz) for a VSWR of less than 2.0. The impedance bandwidth covers multiband operations for mobile and satellite communication. We also present the measured radiation patterns and gain characteristics of the proposed antenna. © 2004 Wiley Periodicals, Inc.
