With this program you can execute mathematical modelling by the phased periodic plane antennas array from circular wave guides in sector of angles and a band …
 


Program #2


GuidesArray Circular is supposed for purposes of modeling of phased antenna arrays created using circular waveguides. Such antenna arrays can be used as transmit \ receive antenna systems for radio- and television-broadcast centers, cellular and paging …


With this program you can execute mathematical modelling by the phased periodic plane antennas array from circular wave guides in sector of angles and a band of frequencies.
The offered mathematical model is founded on an electrodynamic solution of a boundary task in a unit mesh of infinite structure.

Results of research of characteristics of printed-circuit vibrator radiators in plane infinite and finite phased arrays. When researching electrodynamical characteristics of the vibrator radiator, the charge method is used. To determine the direction diagram in the finite array, …


The radiator in question is a thin metallic plate, located on a single side of the dielectric substrate with dielectric permittivity ε and thickness z0. The opposite side of the substrate is metallized. Characteristics of radiators in the infinite array are studied in the excitation mode, when the voltage in the vibrator gap is constant modulus and characterized by ramp phase from radiator to radiator.

In section of “Publications-Books” the “Theory and analysis of phased array antennas” book is published. Authors: N. Amitay, V. Galindo, C. P. Wu.


Arrays of waveguide radiators are the subject in the book. The spectral domain method is used extensively. Small finile arrays are solved via equations over the modes and elements. This work is one of the first using multimode spectral analysis.
