Abstract
An antenna system includes a heptagonal antenna array having one center antenna element and seven circumferentially surrounding antenna elements offering improved near and far sidelobe rejection, which is well suited for mechanically-gimbaled and time delayed electrical steering antenna applications.
Claims8
A system for projecting an antenna pattern, the antenna pattern having a main beam, having a nearest sidelobe beam, and having furthest sidelobe beams, the system comprising,
- one center antenna element,
- seven outer antenna elements surrounding the center antenna element, the one center antenna element and the seven outer antenna elements total eight antenna elements,
- a communications transceiver for communicating signals through the eight antenna elements,
- gimbal motors for mechanically steering the eight antenna elements, and
- a gimbal controller for providing the gimbal motors with gimbal control signals for pointing the eight antenna in a first direction.
