- Abstract
This work describes the use of switched slits and slots to reconfigure the operating frequency and the radiation pattern of a Yagi patch antenna. The Yagi patch antenna is fabricated on the top side of a grounded substrate and is fed by a coaxial probe. By using switches to reconfigure the silts etched on the driven patch, the antenna can operate at two frequencies of 8.175 and 9.31 GHz. By changing the states of the slots etched on different parasitic element patches, directions of the radiation pattern can be changed. Thus, a design that is reconfigurable in both frequency and radiation pattern is accomplished. As a proof of concept, five models are fabricated and tested. Three of them operate at the higher frequency and two of them at the lower one. The main beams of these models point to different directions in the E-plane. Simulated and measured results are given and they are in good agreement. The antenna can be used in radar, satellite communications, etc. © 2008 Wiley Periodicals, Inc.
