The characteristic cross-polarization (X-pol) of wide angle impedance matching (WAIM) structures is investigated. The study considers an ideal linearly polarized current sheet in the presence of various dielectric and artificial dielectric superstrates, analyzed using transmissio

Wideband wide-scanning antenna arrays have been gaining popularity in the past decade due to their applicability in multiple fields and applications. Wideband arrays are desired due to their ability to combine multiple functions or services in a single aperture. The need for ultr

We present an efficient method for the analysis of finite connected slot arrays in the presence of stratified media. The formulation is based on a spectral method of moments, where only one basis function is considered for each array element and one for each slot edge. An express

We present the unit cell design of a wideband wide-scanning phased array operating in both Ku- and Ka-bands, for satellite communication applications. The radiating elements are dual-polarized connected slots loaded with an artificial dielectric superstrate, acting as a wide angl

Connected arrays of slots loaded with artificial dielectric layers have been proposed to realize wideband phased arrays with large scan capability. The role of the artificial dielectric superstrate is to provide a wide angle impedance matching transformation from the impedance at
