Abstract

This article presents a frequency‐reconfigurable printed inverted‐F antenna for terrestrial broadcast applications. To reconfigure the operating frequency, PIN diodes and variable capacitor diodes are used in this antenna structure. To expand its operating frequency bandwidth, two inverted‐F radiators are integrated on the same printed circuit board. Simulation and measurement results show the operating frequencies can be controlled with the junction capacitance or the reversed‐bias voltage of varicaps. The far‐field radiation patterns shows that they are nearly omnidirectional within the reconfigurable frequency band. © 2011 Wiley Periodicals, Inc.
