Perfect magnetic conductors (PMCs) can help in the enhancement of antenna impedance bandwidth using their capability of reflecting the incident waves without phase reversal. The purpose of this paper is to show the advantages of using a perfect magnetic conductor in antenna engineering. The goal is to use it in waveguide-fed slot array antennas, increasing both the antenna impedance and ... Waveguide slot array antenna with EBG high-impedance ... Waveguide slot array antenna with EBG high-impedance surface structure Abstract: A method of raising the front to back (F/B) ratio on the pattern for the slot array antenna of rectangular waveguide using electromagnetic band-gap (EBG) structure as a high-impedance ground plane is studied in this paper. An example antenna is designed and measured. CN105932424A - Waveguide slot array antenna - Google Patents
Investigation and Design of a Slotted Waveguide Antenna ...
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. Radar Basics - Slot Antennas | Slotted Waveguide … Slot radiators or slot antennas are antennas that are used in the frequency range from about 300 MHz to 25 GHz. They are often used in navigation radar usually as an array fed by a waveguide.Slot antennas in waveguides provide an economical way of the design of antenna arrays.

The procedure to design a waveguide slot array antenna is explained, and also the analysis model to design the element is discussed as well as the scattering matrix in connecting the equivalent circuit with a transmission line. Finally, the design examples for one-dimensional and two-dimensional arrays of the waveguide slot antennas are explained.
Waveguide Slot Array | WIPL-D Slotted waveguide arrays consist of a number of slots cut into the walls of a waveguide forming an array with the slots acting as individual radiating elements. The specific design task here is a 10-element transversal slot array cut into the upper wide side of a WR-51 standard rectangular waveguide. 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 ...
