Small reflector antenna with low sidelobes

Abstract

A prime focus low sidelobe parabolic reflector antenna with self-supported feed is designed for low sidelobe applications. The parabolic reflector diameter is between nine and 12 wavelengths. A simple design is achieved to satisfy the required first sidelobe level. The design is performed numerically using a computer code for bodies of revolutions (AKBOR2). The measured radiation patterns of the 18-in reflector system are presented. Good agreement between computed and measured radiation patterns is obtained.

Hybrid CAD techniques for the efficient full-wave optimization of arbitrarily shaped waveguide components and large aperture antennas

“…4, are attractive components as they are inexpensive, have high performance, and are simple to maintain [16]. Because of their compact size, the presence of the dielectric, and the nearfield effects of the subreflector, rigorous techniques are required for accurate pattern and input reflection factor prediction.…”

Design of an Amplitude-Tapered Corporate-Feed Slot Array Antenna with Reduced Side-Lobe Level for Silicon Micromachining

“…Reflector antennas have a significant share of high-gain antennas, such as satellite communication [5]- [8], due to their low sidelobe levels. Designing such antennas is timeconsuming as both the feed and the reflector must be optimized individually and in their interaction.…”

A novel suspended stripline-fed printed square slot array antenna with high-gain

“…As Heinrich Hertz designed the first antenna in 1888 in his experiment for verifying the existence of electromagnetic waves, a lot of antennas with directional radiation patterns have been proposed, e.g. Yagi-Uda antennas [1], horn antennas [2], corner reflectors [3], parabolic antennas [4], etc. Among them, planar printed antenna structures have been widely investigated and are attractive for their light weight, compactness, and cost-effectiveness.…”
