Abstract
A low-profile circularly polarized isoflux antenna module is provided, which relates to the field of microelectronic antennas, and provides a solution to solve the contradiction between size and gain in conventional technology. The antenna module includes an antenna array, a substrate, a connection plate, and a feeding plate that are stacked in sequence. The feeding network on the feeding plate is electrically connected to the antenna array through probe passing through the connection plate and the substrate. The antenna array includes two or more concentrically distributed antenna elements, and each antenna element forms mutually independent concentric circularly polarized apertures through feed control. The structure is simple to assemble and easy to process, light in weight, small in size, and low in profile.
