IEEE Transactions on Antennas and Propagation, 2012, vol. 60, no. 1, p. 20–29.

A slot array antenna is composed of a rectangular waveguide formed by means of oppositely disposed plates and side plates, and a power feeder means connected to the rectangular waveguide at a power feed opening.

Abstract: This paper introduces a rectangular grating waveguide slot array antenna that provides a method for the design of satellite communication (SATCOM) receiving antennas. By integrating the radiating slots with a rectangular grating waveguide, which functions as a frequency-selective transmission line, the antenna realizes an extra filtering response. Slotted Waveguide Array Antennas | SAGE Millimeter Our Slotted Waveguide Array Antennas take advantage of the low loss nature of the waveguide and printed circuit manufacturing process to offer high performance and loss cost solutions.

A distribution network for a modified space-fed phased array antenna consists of a planar array of radiating slots distributed along a coplanar wall in each of an ensemble of parallel waveguides.

Slotted waveguide antennas have been a popular choice for mechani-cally steered antennas since the 1970’s and are found in a variety of 3D radar antennas. 1.1 Problem Statement. The radiation pattern performance of linear arrays is often measured in a plane perpendicular to the array direction...

Radar Basics - Slot Antennas Slot antennas in waveguides provide an economical way of the design of antenna arrays. The position, shape and orientation of the slots will determine how (or if) they radiate. Figure 3 shows a rectangular waveguide with a drawn with red lines snapshot of the schematic current distribution in the waveguide walls. Waveguide Slot Array Antennas - Springer A waveguide slot antenna is a radiating slot antenna cut on a waveguide. This chapter focuses on slot antennas and their arrays on rectangular waveguide(s) of metal. Typically, the waveguide is hollow but sometimes it is filled with dielectric to reduce the guided wavelength. The waveguide slot antenna has features of low loss and high-power ...
