The discovery of the Rotman lens (Rotman, W. and Turner, R.F., 1963) was an enabling technology that greatly increased the capabilities of multibeam antennas. The original intent of the inventor (WR) was somewhat less ambitious. He wanted to study va

Several new antenna designs use the trough waveguide as a transmission line. Among the most recent are linear arrays made of resonant or non-resonant monopoles, slow-wave structures, a hybrid type of TEM-to-trough-guide mode isolator, and a trirod va

The microwave antenna described utilizes a trough waveguide array feeding a section of a parabolic cylinder. Performance of the antenna, a linear array, depends on several properties of the trough waveguide. Electromechanical scanning of the array is

The bandwidth limitation in space fed phased arrays (that results from the use of phase shifters to implement beam steering) is overcome by a lens arrangement in which independent feeds are provided at the focal plane of the lens. Each feed generates

Two new types of microwave antennas have been invented. The first consists of an undulating conductor surrounded by straight conductors at ground potential. When the period of undulation is a wavelength long, transversely-polarized broadside radiatio
