Waveguide Slot Antenna Arrays 9-2 CHAPTER NINE 9.1 INTRODUCTIO Geometric simplicity, efficiency, polarization purity, conformal installation, and ability to radi- ate broadside beams and vertically polarized E-plane beams at very near grazing angle above a ground plane make slot-antenna arrays ideal solutions for many radar, communications, and navigation applications. Especially today with the desire to make antennas for aircraft as low profile as possible to reduce drag and conserve fuel, slot antenna arrays can be positioned above wings and on top of the fuselage while having the capability to look toward t
