In this paper, a design of reconfigurable printed antenna is presented. The antenna consists of square patch excited by a coaxial probe and adopted to operate at the frequency of 2.45GHz. By placing a variable capacitor in the antenna, it allows to reduce the antenna size with a wide range starting from 2.45GHz to 1.65GHz. We study the positions of the chip capacitor on the resonance frequency of the patch antenna.Prototype of the antenna and related results are presented and discussed.
Abstract-A compact multiband frequency reconfigurable meander antenna proposed for wireless communication systems is designed and described in this paper. A folded structure has been chosen due its good tradeoff between size, bandwidth and efficiency. The reference antenna is based on a meander patch structure radiating at F1=1, F2=1.94, F3=2.6GHz and optimized to be integrated in the Printed Circuit Board (PCB). In order to sweep the resonance frequencies, a chip capacitor was inserted between the meander patch printed on the top layer and a floating ground plane on the back one, in first case. Than in second case, by inserting a varactor diode to tuning electronically the resonance frequencies over wide bands. The measured results agree with simulations and good radiation properties were obtained. Realized prototype and related results are indeed presented and discussed.
