Abstract
To help with long range coverage, minimal interference, and reduced energy requirements, recent studies have incorporated directional antenna arrays in wireless communication networks. In this letter, a broadband, dual polarization, and very narrow beam (<;11°) antenna array system based on the Long Slot Antenna (LSA) array technology has been developed, prototyped and tested. The complex feeding structure of the antenna array was simplified with a novel aperture metallic patch design using 50 - 60Ω microstrip lines. HFSS simulation and experimental beamwidth results are in excellent agreement (<;11° difference).
