Analysis of microstrip antennas on carbon fiber composite material

Abstract

In this paper a truncated corner rectangular microstrip antenna (TCRMA) is analyzed in the presence of carbon fiber composite (CFC) material. Simplified carbon fiber composite models are proposed and the analyses are performed by the electromagnetic simulator Computer Simulation Technologies (CST). Theoretical and experimental results of return loss, axial ratio, input impedance and radiation pattern for the antenna located on the aluminum and CFC plates are presented and compared. The results show that the proposed models can be used as a good approximation of the CFC sample and that the CFC material is a feasible alternative instead of aluminum for antenna applications on complex structures such as ships or airplanes.

CPW Fed Flexible Graphene Based Thin Dual Band Antenna for Smart Wireless Devices

“…Flexible devices using Graphene structure for NFC communication, RFID tags, and transmission line for wireless communication systems are analyzed in the literature [4][5][6][7]. However, many researchers try to investigate the antenna with the help of conductive carbon fiber composite materials which have brought a lot of other possibilities for making flexible structures [8][9][10]. Such antennas fall into the category of transparent antennas where many researchers have proposed dual-band, wideband antennas with different materials like Silver doped Tin Oxide (AgHT), Indium Tin Oxide (ITO), Zinc Oxide (AZO), etc.…”

Gain enhanced conformal patch antenna with defected ground for aircraft applications

“…In recent days, aircraft structural parts are replaced by composite materials [18], which is made of aluminium or carbon fibres. Though the composition of composite material differs by the shape, size of the component and concentration percentage, the permittivity and permeability calculation is [19] simplified by the law of mixtures [20,21]. As the performance of the aluminium composites is also similar to carbon fibre composites (CFC) [19], the CFC sheets are used in the experimental setups both in design and measurement.…”

Carbon Fiber Reinforced Polymer With Isotropic 60 GHZ Reflectivity

“…Antennas are built from CFRP [1,2], but more commonly large CFRP parts are applied as antenna ground planes [3][4][5][6][7], reflectors [8] or panels for slot antennas [9][10][11]. Airplanes, boats, car chassis and sports equipment are today built with CFRP.…”
