Problems solved by technology

[0006] Single-axis electrical steering panels are simpler and less expensive than full 2D scanning phased arrays, but have narrower azimuth beamwidths, which maintain high requirements for pointing accuracy and response time of mechanical actuators

Embodiment Construction

[0025] The present disclosure relates to a specific design of the lens array antenna such as, for example, in U.S. Patent No. 10, 116, 051 to support design simplification, cost reduction, and increased design flexibility between the wearing axis and scan antenna gain performance. . The full content of '051 patent is incorporated herein by reference.

[0026] refer to figure 1 (a), 1 (b), showing the base mixing mechanical lens array antenna assembly 101 (side view figure 1 (a), top view figure 1 (b)). This antenna is called a hybrid antenna because it uses a combination of electrometrum formation and mechanical steering to point beams to the entire field of view. The antenna 101 includes a lens array 120, a housing 105, a rotating platform 109, and a rotating actuator 107 that are substantially planar. The lens array 120 is formed from a plurality of lens modules 121 (hereinafter sometimes referred to as a lens), and the plurality of lens modules are arranged substantially flat e...

Abstract

A hybrid mechanical-lens array antenna is described that can be configured with different orientations and arrangements of the plurality of lenses within the array to control and enhance the performance at different regions of scan. This can include the addition of a secondary array (a skirt) at a large tilt angle, tilting the primary array, tilting the individual lenses within the primary array, or any combination. These design choices, when holding the number of lens modules (and, therefore, cost and power consumption) constant, have the effect of changing the system height, reducing the boresight gain and increasing the gain at scan, with each option showing different trades of height and scan and boresight performance.

Description

[0001] Application [0002] The present application claims priority to US Provisional Application No. 62 / 842905, filed on 3 May 2019, which is dependent and incorporated herein by reference. Technical field [0003] The present disclosure relates to a method and system for improving a gain rolling drop in a scanning of a hybrid mechanical lens antenna, which is used for satellite or terrestrial communication. The present disclosure more particularly a method and system for configuring a lens element having various tilting and rotational arrangement. Background technique [0004] Mainly due to the reduction in the antenna aperture area in the scanning direction, the array of planar elements is substantially a gain attenuation during elevation scanning. Manda-direction (GIMBALED, universal fixed, universal joint, universal joint) parabolic antenna and universal flat antenna overcome this gain attenuation by continuously pointing the entire antenna to the desired scanning direction b...
