Antenna Array Design and System for Directional Networking

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).
