WebbThis paper presents two designs of high-efficiency polarizer reflectarray antennas able to generate a collimated beam in dual-circular polarization using a linearly polarized feed, … WebbPyramidal horn antennas for a variety of frequencies. They have flanges at the top to attach to standard waveguides. A horn antenna or microwave horn is an antenna that consists of a flaring metal waveguide shaped like a horn to direct radio waves in a beam. Horns are widely used as antennas at UHF and microwave frequencies, above 300 MHz. …

WebbAn early phased array, the antenna radiated a vertical fan-shaped beam which could be swept horizontally across the airspace in front of the antenna. An antenna array (or array antenna) is a set of multiple connected antennas which work together as a single antenna, to transmit or receive radio waves. The individual antennas (called elements ... WebbThe analysis of the shaped reflector antenna, is performed by physical optics (PO) method in commercial package, FEKO. The fitness value for each population is calculated, which is the differences between the desired and evaluated radiation patterns. The desired radiation patterns in both azimuth and elevation planes are shown in Fig. 2.
WebbFan beam antennas are used in radar sets. Primary radar in airport have often fan-beam with the section of antenna oriented horizontally to give a narrow beam in azimuth. They …
WebbThis paper investigates a 220 GHz quasi-optical antenna for millimeter-wave wireless power transmission. The quasi-optical antenna consists of an offset dual reflector, and fed by a Gaussian beam that is based on the output characteristics of a high-power millimeter-wave radiation source-gyrotron.
