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... Article - LTCC Partially-Filled Post-Wall Rectangular-… In the millimeter-wave band, the series-fed array antenna is facing a problem of large transmission loss and narrow bandwidth by using a high-permittivity... 8.5 waveguide-fed slot antennas 8.4 CAVITY-BACKED RECTANGULAR SLOT ANTENNAS The electric field on the coaxially fed, cavity-backed rectangular slot (see Figure 8-6a) is8.5 waveguide-fed slot antennas. The waveguide opening onto a ground plane is commonly used in phased arrays and as a single element... Micromachined millimeter wave A rectangular coaxial line to ridge waveguide transition is designed to feed the H-plane horn antenna and the ridge waveguide slot antenna.Butler matrix with a patch antenna array exhibits the forming of the beams at ±17° as expected from the theoretical calculation. Acknowledgements.
A flat phased array antenna for reception of circularly polarized high frequency signals. The flat antenna array consists of a number of subarrays arranged in a matrix. In turn, each of the subarrays consist of individual antenna elements …
Radioengineering - September 2017, Volume 26, Number 3 [DOI: 10… The proposed antenna, which is built on a single-layer substrate, consists of five parts: a short-ended SIW, a centro-symmetric wide slot, an L-shaped probe, a circular horn and a transition from SIW to air-filled rectangular waveguide for … US5041840A - Multiple frequency antenna feed - Google Patents A multiple band antenna feed used with parabolic reflector antennas and the like. The feed is arranged as two coaxially disposed waveguides. A planar array of patch elements is disposed at the end of the coaxial waveguides so the energy in … US2405242A - Microwave radio transmission - Google Patents

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 ...
