Paper Abstract

In this paper we describe a circular antenna array that consists of four small cavity-backed slot antennas (CBSA) integrated with a cylindrical case of wireless battlefield sensors operating in ISM 2.4 GHz band. The array antenna is dedicated to operate in a switched-beam mode, in which the active element is selected by means of a microwave switching network. We put our focus on simulated and measured parameters of CBSA elements that should provide sector coverage in the horizontal plane of a single quadrant of the battlefield. We show that the proposed cavity-backed slot antennas operates with low reflection coefficient (<17 dB) in frequency bandwidth of 150 MHz (6.2%). Moreover, the width of its horizontal radiation pattern is ca. 76°, which is sufficient for coverage of a single quadrant of the battlefield in order to provide reliable wireless communication.
