Abstract
A simple septagon slotted, frequency and radiation pattern reconfigurable microstrip patch antenna is proposed in this paper. The antenna operates in the C band and is capable of switching between two different frequencies 3.9 GHz and 5.9 GHz. The radiation pattern can be reconfigured between boresight pattern and conical pattern. Beam Lead PIN diodes (MA4AGBLP912) are used as switching element for reconfiguring the frequency and radiation pattern. Two parasitic elements are used; a circular ring for frequency reconfiguration and shorting posts for radiation pattern reconfiguration.
