Abstract
A method for wide-band wide-angle impedance matching of rectangular waveguide phased arrays is presented. A maximum VSWR of 2.3:1 is achieved over a 50 percent bandwidth with a 
half-angle conical coverage using an element spacing six percent less than the condition required for grating lobe suppression. A further reduction in element spacing, bandwidth, or scan volume results in an even better impedance match. Simplicity and high radiation efficiency are the unique features of this matching technique.
