Design of slotted patch antenna based on photonic crystal for wireless communication

摘要

Nowadays, the wireless communication is improved in numerous ranges, and the use of the high speed of data rate in the communication systems is needed. The standing problem of high-performance planar antenna is reduced by the recently developed artificial dielectric called photonic crystal, which is used to control and manipulate the optical property of light. This paper addresses the slotted tube antenna structure, and the investigation is done by the concept of triangular lattice structure based on the photonic crystal. This utility enhances the return loss of -57.81 dB and the voltage standing wave ratio (VSWR) of 1.002 at 2.37 THz operating frequencies. The increase in hole radius provides the shifting in zero dispersion point towards the shorter wavelength that helps for faster data rate transmission applications. Further, to characterize the model of the proposed antenna, the optimal value of the air hole, lattice constant value between holes and the thickness of the slot are found and the related parameters of such antenna are studied with the support of simulation software CST microwave studio.
