Embodiment Construction

[0036]Disclosed herein are example embodiments of a switchable artificial magnetic conductor (S-AMC) and an agile antenna device that includes an array of S-AMC for beam steering for broadband wireless transmission. As disclosed herein, the terms radio frequency (RF) and RF signal are respectively used to denote frequencies and signals in the RF spectrum region suitable for wireless communication. These RF spectrums include, but are not limited to, ultra high frequency (ultra high frequency, UHF), super highfrequency (SHF), and extremely high frequency (EHF) bands.

[0037]AMC (also called high impedance surface) is an artificially engineered material whose surface is equivalent to a magnetic conductor in a specific frequency band. The AMC structure is usually realized by using periodic structures printed on a dielectric substrate with various metallization patterns. Among its characteristics, the two characteristics of the AMC surface have produced a wide range of microwave circuit ap...

Abstract

A switchable artificial magnetic conductor (S-AMC) element that includes a conductive layer, a conductive patch located on one side of the conductive layer and electrically isolated from the conductive layer, and an open stub located on an opposite side of the conductive layer and electrically isolated from the conductive layer. A switch element is configured to selectively open and close an electrical connection between the conductive patch and the open stub in response to a control signal. When the electrical connection is closed the conductive patch presents a high impedance, magnetically conductive surface for radio frequency (RF) signals within a defined frequency band, and when the electrical connection is open the conductive patch presents an electrically conductive surface for RF signals within the defined frequency band.

Description

[0001]Cross references to related applications[0002]This application claims the priority of the U.S. patent application filed on June 15, 2018 under the title "Reconfigurable Radial Waveguide with Switchable Artificial Magnetic Conductor" and Application No. 16 / 009,980, and its entire contents Incorporated into this article by way of introduction.Technical field[0003]The present disclosure relates to antenna design, and in certain embodiments, it relates to a device and method of reconfigurable waveguide antenna array and a device and method of switchable artificial magnetic conductor used in the waveguide.Background technique[0004]Radio frequency (RF) transmitters use antennas to propagate wireless RF signals. The shape of the antenna and the RF signal processing technology enable beam steering. Beam steering allows spatial selectivity in the position of the main lobe direction of the radiation signal. Traditional beam steering technology relies on controlling the phase of the RF s...
