Abstract :
In this paper, we proposed a frequency reconfigurable antenna design for loop antenna with dual band resonance frequencies. The current path of the antenna is electronic controlled by PIN diode switch for the desired resonance frequency. The larger/smaller of the current path, the smaller/larger of the resonance frequency can be obtained. The simulation and measurement of resonance frequency and overall efficiency are compared. The trends of results for PIN diode is either in “ON” state or “OFF” state are agreed.
