UNIVERSITY OF CALGARY A 460 GHz CMOS Substrate-Integrated-Waveguide Slot Antenna by Hao Xie A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES IN PARTIAL Radar Basics - Slot Antennas 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 ...

Waveguide Slot Antenna Design by KB7TRZ; Antennas: The Slotted Waveguide Antenna Figure 4. Slotted waveguide antenna fed by a coaxial feed. The resulting S-parameter graph is shown in the following figure. Note 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. The bandwidth of the antenna (if defined as where S11 is less than -6 dB) extends ... ex W1GHZAntenna Book W1GHZAntenna BookW1GHZAntenna Book ...

Multi-beam monopulse substrate integrated waveguide slot ... Abstract: A multi-beam slot array antenna is proposed in the 10-GHz band for a monopulse tracking system with resolution enhancement techniques. The antenna architecture combines a four-subarray substrate integrated waveguide (SIW) slot antenna, a multi-beam-forming network of microstrip Rotman lens array, and a SIW comparator of four-quadrant monopulse technique.

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. 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.
