Abstract
The method of producing antennas and antenna arrays with desired beam widths applies to both single and dual polarization antennas, and controls and modifies the radiation patterns of the antenna's radiating elements by placing appropriately designed parasitic elements in their vicinity.
Claims15
A method of producing an antenna or antenna array with a desired beam width, comprising:
- forming a radiating element having a radiation pattern;
- and
- controlling the radiation pattern to have a desired beam width by forming parasitic elements in association with the radiating element.
A method of producing a dual polarization antenna or antenna array with desired beam widths for each polarization, comprising:
- forming a radiating element having a first and second radiation pattern of a first and second polarization, respectively;
- controlling the first and second radiation patterns to have first and second desired beam widths, respectively, by forming parasitic elements in association with the radiating element.
An antenna or antenna array, comprising:
- a radiating element formed on a substrate;
- and
- first parasitic elements formed on said substrate adjacent to opposite sides of said radiating element, said first parasitic elements separated from said radiating element and dimensioned to cause said radiating element to produce a radiation pattern of a first polarization with a first desired beam width.
