Embodiment Construction

[0047] In the following description, various specific embodiments of the present disclosure are described in detail. However, it will be understood by those skilled in the art that the invention claimed herein may be practiced without all of the specific details given below. In other instances, well-known features have not been described in order not to obscure the invention.

[0048] Figure 2 shows an electronically steerable artificial impedance surface antenna (AISA) provided by the present disclosure, which is relatively low in cost and can be controlled at angles θ and Angular controllable. image 3 is a diagram of the spherical coordinate system, the figure shows the angle θ and horn. exist image 3 middle, The angles are the angles in the X-Y plane, and the angle θ is the angle formed from the z-axis. Because the main gain lobe of the electronic controllable artificial impedance surface antenna (AISA) of the present invention is at θ angle and Those skilled i...

Abstract

A steerable artificial impedance surface antenna steerable in phi and theta angles including a dielectric substrate, a plurality of metallic strips on a first surface of the dielectric substrate, the metallic strips spaced apart across a length of the dielectric substrate and each metallic strip extending along a width of the dielectric substrate, and surface wave feeds spaced apart along the width of the dielectric substrate near an edge of the dielectric substrate, wherein the dielectric substrate is substantially in an X-Y plane defined by an X axis and a Y axis, wherein the phi angle is an angle in the X-Y plane relative to the X axis, and wherein the theta angle is an angle relative to a Z axis orthogonal to the X-Y plane.
