The Friis equation is often used to determine the gain of antennas but assumes that far-field conditions are met. For limited antenna separations on the order of the Fraunhofer distance, its use requires a precise estimate of the amplitude centers of

New applications like 5G and car radar require higher operating frequencies. For higher frequencies the size of a typical packaged IC is of the same order of magnitude of one or more waveguide cross-sections, giving the opportunity to use the wavegui

High-quality circular polarization is obtained using a novel concept that uses a sparse random distribution of randomly-rotated linearly-polarized antennas. Key benefit of this concept is that a very narrow circularly-polarized beam is obtained with

Focal and axial fields of the parabolic and spherical quasi-optical antenna systems are analyzed. The effects of axially displaced focal plane array (FPA) in both systems were investigated. The axially displaced FPA-fed parabolic reflector can broade
