Frequency reconfigurable PIFA antenna driven by microcontroller

This paper proposes a method of controlling the operation of the frequency reconfigurable planar invert F antenna (FRPIFA antenna) by a microcontroller (MCU). The MCU is integrated onboard with antenna. In order to tune the antenna operating frequency, the operation of PIN diode-electronic switches is done by programs written in memory of this MCU. The use of a MCU allows custom adjustment of the operation of PIN diode through the program and also allows an easy connection between Personal Computer (PC) and antenna. Simulation and measurement results of antenna parameters validate the performance as well as the application of the developed antenna.
