This article presents the results of numerical and experimental evaluation of performance of the Vlasov antenna in view of High Power Microwave (HPM) applications. The impact of the antenna geometry on its parameters, i.e. shape of the radiation pattern and the directional gain, is shown. Also, critical values of the electric field intensity that can excite electrical discharge are determined and trouble spots of plasma generation within antenna geometry that can block HPM emission are also determined.
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.
