The application of a 3D domain decomposition finite-element and spherical mode expansion for the design of planar ESPAR (electronically steerable passive array radiator) made with probe-fed circular microstrip patches is presented in this work. A global generalized scattering matrix (GSM) in terms of spherical modes is obtained analytically from the GSM of the isolated patches by usin... https://www.ealisboa.com/mega-deal-OtterBox-Defender-Case-for-Samsung-Galaxy-S23-Ultra-top-savings/
