Constantine A. Balanis is a Greek-born American scientist, educator, author, and Regents Professor at Arizona State University. Born in Trikala, Greece on October 29, 1938. He is best known for his books in the fields of engineering electromagnetics and antenna theory. He emigrated to the United States in 1955, where he studied electrical ...
Selected uses in antenna theory include the analysis of aperture antennas [9] and the cavity model approach for microstrip patch antennas. [10] It has also been used as a domain decomposition method for method of moments analysis of complex antenna structures. [11] Schelkunoff's formulation is employed particularly for scattering problems. [2 ...
The antenna elements fed by a Butler matrix are typically horn antennae at the microwave frequencies at which Butler matrices are usually used. [4] Horns have limited bandwidth and more complex antennae may be used if more than an octave is required. [5]

The thinned-array curse (sometimes, sparse-array curse) is a theorem in electromagnetic theory of antennas.It states that a transmitting antenna which is synthesized from a coherent phased array of smaller antenna apertures that are spaced apart will have a smaller minimum beam spot size, but the amount of power that is beamed into this main lobe is reduced by an exactly proportional amount ...
The antenna pattern is the response of the antenna to a plane wave incident from a given direction or the relative power density of the wave transmitted by the antenna in a given direction. For a reciprocal antenna, these two patterns are identical. A multitude of antenna pattern measurement techniques have been developed.

Crossed-dipole antenna array of station KENZ's 94.9 MHz, 48 kW transmitter on Lake Mountain, Utah. It radiates circularly polarized radio waves. It radiates circularly polarized radio waves. FM broadcast radio stations sometimes employ circular polarization to improve signal penetration into buildings and vehicles.
