摘要: Surfaces act as perfect magnetic conductors (PMC) if the phase shift of reflection an electromagnetic wave amounts to 180/spl deg/ compared at a electric conductor (PEC). One possibility create PMC surfaces artificially is array closely spaced patches. In this paper, based on relation between and patch antennas, explanation for functioning artificial given. An equivalent network derived that allows understand provide starting design numerical optimization by aid fullwave methods. A planar used first time reflector large aperture coupled antenna array, especially in order reduce parallel-plate modes are usually present traditional arrays. additional sidelobe suppression over 6 dB has been achieved comparison reflector.
