Study of a MIC - Phased Array Antenna for Man - Transportable Solid State Search Radar

This work describes a possible approach towards the design of a particular class of phased array such as MIC solid state antenna array for search radars. The main characteristics of such an antenna are brought out in accordance with a general theory of open - ended waveguide planar array[l]. The electromagnetic field problem for the single MIC radiating element is developed on the basis of the model having an imperfect electric and magnetic wall cavity[2], obtaining theoretical formulas which agree very well with experimental results. The mutual coupling coefficient between rectangular X-band MIC antennas has been considered too and a new general formula, in close agreement with the experimental data, has been determined. A description of synthesizing method for symmetrically and asymmetrically shaped beams with a numerical evaluation of the radiating characteristics of an X-band MIC planar array antenna having an E - plane "pencil" beam and an H-plane "quasi cosec2" shaped beam is given.
