spilloverloss
- In double reflector antennas feed, feed support beams and sub-reflector especially cause distribution losses and large blockings in antenna apertures. In previous studies, the spillover losses due to open-ended rectangular and circular sectio
L18_Horns
- Rectangular horn antennas Horn antennas are popular in the microwave band (above 1 GHz). Horns provide high gain, low VSWR (with waveguide feeds), relatively wide bandwidth, and they are not difficult to make. There are three basic types of r
Horn_Corrugation_Design
- The corrugations present a capacitive reactance to the passing wave. When a corrugated surface is inductive, it will support surface waves. The depth of corrugations must be between λ/4 and λ/2. Less than λ/4 or greater than λ/2, it is inductive. Bet
8.4.1-Feed-Sidelobe-Illumination
- When we feed a reflector with a narrow beam feed antenna, the narrow beam will under-illuminate the reflector causing reduce the amplitude taper efficiency while decreasing the feed power spilled past the rim of the reflector. However, the feed sidel
