Reconfigurable Patch Antenna Design Using Pin Diodes and Raspberry PI for Portable Device Application

摘要

The modern wireless communication system requires high performance portable devices, thus designing of such communicating devices plays a major role. More particularly, meander shape is selected over the traditional shapes of microstrip patch antenna for the application of portable device antenna. Accordingly, in this paper, orthogonal meander architecture along with PIN diodes are proposed to achieve vertical and horizontal polarization. Further, to control switching of PIN diodes, Raspberry PI system is employed. In the proposed method, a novel meander-shaped antenna is designed and simulated using High-Frequency Structure Simulator-11 (HFSS-11) with an operating frequency of 2.4 GHz. However, the optimized design dimensions are used to fabricate the antenna and then the results are verified. This paper highlights the simulated and experimental results including, S-Parameter, radiation pattern, current distribution, co and cross polarization, path loss and impedance. Besides, the paper demonstrates the effect of cover on the antenna performance. Finally, the proposed meander shape reconfigurable antenna have validated as a portable device antenna from the obtained results for wireless communication applications.
