Abstract :
In this paper, An electronically tuned circular patch antenna with good radiation pattern is proposed and studies. patch antenna has been designed with predicted obtainable tuning range. Electronic tunablity is achieved by connecting Varactor diodes thus altering the capacitance of the patch and hence resonant frequency. Although this antenna has a low bandwidth, electronic tuning allow a large band to covered with maintaining the same narrow band operational characteristics. RT-Duroid 5880 substrate (ϵr = 2.3) with thickness of 0.8 mm used in this design. Proposed antenna performance is evaluated by compairing results.
