Title:
DIFFERENTIAL-MODE APERTURE-COUPLED PATCH ANTENNA
Document Type and Number:
WIPO Patent Application WO/2020/015728
Kind Code:
A1
Abstract:
An aperture-coupled patch antenna is described. The antenna includes at least one radiating patch. A first aperture couples a reception signal from the patch to first and second receive ports. A second orthogonal aperture couples a transmission signal from a transmit port to the patch. The transmit feed circuit is a single-ended feed circuit. The receive feed circuit is a differential-mode feed circuit. The receive feed circuit defines a difference port, where the electrical path lengths from the first receive port to the difference port and from the second receive port to the difference port differ by an odd integer multiple of half a signal wavelength. The receive feed circuit also defines a sum port, where the electrical path lengths from the first receive port to the sum port and from the second receive port to the sum port are equal in path length.
