Abstract :
A varactor tuned microstrip patch antenna has been designed and developed, with a view to predicting the obtainable tunable range. Tunability is achieved by connecting varactor diodes thus altering the capacitance of the patch and hence resonant frequency. Although this antenna has a narrow instantaneous bandwidth, electronic tuning allow a large band to covered whilst maintaining the same good narrow band operational characteristics. Evaluation of the antennapsilas performance is provided by practical results.
