Fabrication of PIN Diode switchable antenna ON and OFF state with different frequencies

A novelette Microstrip patch antenna restructuring with the fabrication of adoptable switchable PIN diode ON and OFF conditions is recommended. The recommended antenna has an uncomplicated framework consists of inverted L-shaped slots that cut along the radiating edge of the reference patch antenna and a PIN diode is inserted between the slots. A PIN diode is fabricated with dielectric constants of substrate 3.2, the dimension of slot 0.40*14.70 mm2 and the length of the metallic strip diode 0.40mm. Simulated and fabricated diode results for diode ON and OFF state which are measured with both practical and ideal diodes. The OFF state resonant frequency is 5.598GHz and the measured frequency is 5.60GHz. Simulated and fabricated results are also checked for diode ON state. The ON state resonant frequency is 4.45GHz and the measured frequency is 4.59GHz. Antenna design simulation is done by using CST software.
