Microstrip Patch Antenna System Design for In-Cabin Wireless Communications and Internet Services

Abstract

Due to the increasing communication requirements, using the internet when air traveling is no longer luxury but it is a necessity. In this paper, a microstrip patch antenna system has been designed which can be used as an access point and provide internet connections at the 5GHz band in the Airbus A321 type of aircraft. The electromagnetic field radiation simulation and positioning of the designed antennas in the aircraft cabin have been performed also. The microstrip antennas have been designed within IEEE 802.11 ac/ax standard. 5GHz WiFi internet service is providing at 5300 MHz (CH 60) center frequency with 4 antennas which FR-4 dielectric material was used. The designed antennas are used as access points and they are connected with a fiber connection. The electromagnetic field radiation of the antennas placed in the cabin was simulated with the HFSS simulation program. As a result of the simulations, these antennas have been observed to be useful.
