Waveguide Phased Array Antenna Analysis and Synthesis
conference paper
Results of two software packages for analysis and synthesis of waveguide phased array antennas are shown. The antennas consist of arrays of open-ended waveguides where irises can be placed in the waveguide apertures and multiple dielectric sheets in front of the apertures in order to accomplish a wide band wide scan angle impedance match. One of the packages is restricted to the use of infinitely thin aperture irises, but has the advantage of fast calculation times. The other package, which has been completed recently, is very versatile and allows multiple (finite thickness) obstacles in the waveguides, but at the cost of longer computation times. The validity of the new software package is demonstrated and a design strategy, using both packages, is discussed. With the newly developed software we expect to have a better control over scan blindness effects.
