A Wideband 2 × 2 Array Antenna with 45-Degree Half-Power Beamwidth for Angular Characterization at 5-to-6 GHz ISM Band

Abstract

This paper proposes an antenna design for angular propagation characterization using the Industrial, Scientific, and Medical (ISM) frequency band. The antenna is a 2 × 2 patch array with a 45-degree half-power beamwidth (HPBW). It covers a wideband range of frequencies at the ISM band from 5 to 6 GHz. The design was simulated and measured, and similar results were obtained. A wideband measurement of 8 antennas in a conformal form showed the angular spread of multiple signals arriving at the receiver side.
