Frequency reconfigurable microstrip antenna using patch switchable slot antenna (pass) technique at 2.4GHz and 3.6GHz / Siti Norhidayah Kamarudin

In this paper, frequency reconfigurable for an aperture coupled microstrip antenna using switchable slot with parasitic element is presented. By putting two small size of copper (w = 0.5mm)which replace as PIN diode, it produce different frequencies with the condition of the switch ON or OFF mode. The parasitic element has been used to improve gain for the antenna by added up on the radiation patch with another substrate. The material which will be use is FR4 for substrate and feed, er = 4.7, tangent loss is 0.019 and the thickness is 0.8mm. The proposed structure was simulated by using CST Microwave Studio software. This design is proposed for wireless application for Wi-Fi (The Standard for Wireless Fidelity) which is 2.4GHz and 3.6 GHz
