Circular Slot Antenna Array Printed On 3D Textile Substrate

Abstract

In the paper, the design of an antenna array consisting of circular slots is presented. Since the antenna is expected being integrated into textile upholstery of a vehicle, a 3D textile material is considered as a substrate in the design. Metallic layers are screen-printed by a silver paste. The array is fed by a textile integrated waveguide which walls are sewed by a conductive thread. The array is designed for the center frequency of the band-group VI (8 GHz) of ultra-wideband communication channels. At the center frequency, the measured realized gain is about 10 dB, and the measured axial ratio equals to 4. The array operates with right-hand circular polarization. The design is verified by measurements.
