Abstract
An apparatus for (and method of) generating circular antenna polarization (from a planar structure encompassing the feed, excitation, and antenna functions), consisting of a plurality of modules each comprising one or more patch antennas, wherein at least one or more of the modules is stacked atop one or more other modules to form a stair-stepped, stadium like antenna array.
Claims19
An apparatus for achieving substantially circular antenna polarization, said apparatus comprising a plurality of modules each comprising one or more patch antennas, wherein one or more of said modules is stacked in a stair-stepped fashion atop one or more other of said modules to form a stair-stepped antenna array emitting electromagnetic radiation from the plurality of modules and wherein each level of modules contains fewer modules than levels below.
A method of generating circular antenna polarization, the method comprising the steps of:
- providing a plurality of modules each comprising one or more patch antennas
- introducing phase staggers between modules to steer emission of the electromagnetic radiation, wherein one or more of the modules is atop one or more other of said modules to form a stair-stepped antenna array emitting electromagnetic radiation from the plurality of modules.
