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. W1GHZ 10GHz Page - Antennas Dick, K2RIW, has been talking about periscope antennas for so long that I had to put one up and show him how to do it! The periscope antenna worked great for rainscatter during the June VHF Contest. I worked four grids on 10 GHz, best DX >130 miles, during heavy rain. 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.

Slot Antenna. 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. Coplanar Waveguide Fed Hexagonal Shaped Slot Antenna for ... fed antenna is designed which improves the radiation patterns of the antenna at high frequency [10]. An antipodal planar tapered slot antenna is designed over a Rogers RO4003 substrate, in addition a resistive layer is placed behind its conductive layers in order to minimize the backward radiation [11]. Applications of Substrate Integrated Waveguide (SIW ... This thesis is focused on some applications of the Substrate Integrated Waveguide (SIW) structure in microwave engineering. It is mainly divided into two parts, covering a dual-band high Q filter and a broadband high gain ring slot antenna, both of which are based on SIW resonators. This work ...
