Description
Summary:A design of frequency reconfigurable patch antennas is presented. The antenna has a radiating patch perpendicular to the ground plane, and it can be regarded as a one‐dimensional suspended patch antenna. By placing two varactors between the radiating patch and ground plane, the operation frequency of the antenna can be tuned from 3.3 to 4.2 GHz, and a stable broadside radiation pattern with low cross‐polarization can be obtained within the operation bandwidth. A prototype of the proposed reconfigurable antenna is constructed. Both measured and simulated results of the prototype are given, and the differences between them are shown.
