OZ2OE Technical Home Page - 10 GHz waveguide slot antenna. Design of a 10 GHz beacon antenna. A standard WG16 waveguide is used. Principle: A slotted waveguide antenna works by radiating energy from the inside though a number of slots cut in the waveguide. Each slot acts as a (slotted) dipole, with the polarity opposite the direction of the slot. A vertical slot gives a horizontal polarisation.

Non-Resonant Slotted Waveguide Antenna Design Method
How a Slotted Waveguide Antenna Works This antenna, called A slotted waveguide, is a very low loss transmission line. It allows to propagate signals to a number of smaller antennas (slots). The signal is coupled into the waveguide with a simple coaxial probe, and as it travels along the guide it traverses the slots. Sidewall Waveguide Slot Antenna for High Power Sidewall Waveguide Slot Antenna for High Power Carl E. Baum University of New Mexico Department of Electrical and Computer Engineering Albuquerque New Mexico 87131 Abstract This paper discusses a concept for high-power microwave antennas based on an array of slots in the sidewall where the electric fields are lower.

Design and analysis of slotted waveguide antenna arrays
A slot array antenna which utilizes air gap waveguide as feeding structure has been proposed in[17].This waveguide has its cutoff frequency for dominant TE10 mode at 39.9GHz, and its inner dimensions are 3.8mm 1.9mm [4]. However in the final design, each component of the antenna... Antennas: The Slotted Waveguide Antenna If the waveguide slot antenna is designed in this manner, then all of the slots can be viewed as being in parallel. Hence, the input admittance and input impedanceNote that the antenna has a very large drop in S11 around 10 GHz. This indicates that most of the power is radiated away at this frequency. 12 Slot Waveguide Antenna for 2.4GHz - YouTube
Highly Directional Slotted Waveguide Antennas. Sometimes it is useful to have a highly directional antenna. For example, when installing a point-to-point linkThe smith chart at the right was computed for the 16 slot uni waveguide. and is plotted for a frequency range from 2410 to 2520 in 10MHz steps...
Design of dual-band and high gain waveguide slot antenna ... A new kind of dual-band and high gain waveguide slot antenna is designed in this paper. By combining a folded plate and a double-layer metal structure with four apertures on its top floor, the proposed antenna has a dual-band characteristic and its gain reaches up to 11.9 dB with only 35 degrees (HPBW) of E-plane at 12.7 GHz and 12.1 dB with 39 degrees at 15.0 GHz.
