摘要
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.
