Investigation of Nano-Structured Honeycomb Patch Antenna with Photonic Crystal Substrate

Abstract

As the requirement of a wireless system is escalating day by day, a low profile system has curiosity toward the microstrip patch antenna. The wireless communication system demands a small and compact antenna that has broader bandwidth than the conventional antenna design. In this chapter, investigation of the honeycomb patch antenna using photonic crystal (PhC) increases the gain and directivity and decreases the power loss. The ultimate aim of the antenna is to be compact and robust, so a microstrip patch antenna is employed. When the return loss gets increased, the signal can transmit over a long distance. The main parameters in this design are return loss, gain, directivity, and voltage standing wave ratio (VSWR). The existing system of the honeycomb patch antenna has a frequency in the range of gigahertz. The proposed system of this chapter is to generate a signal in the terahertz frequency. Computer simulation technology software is utilized for this design simulation. In this article, two antennas are used as a conventional antenna and an antenna on PhC. The return loss of the conventional antenna is -35.44 dB at 11.30 THz. The return loss of the antenna on a PhC substrate is -44.14 dB at the 14.72 THz. This antenna is applicable in the domain of aircraft, military, and other wireless communications.
