Abstract
An equivalent circuit model of a quadraxial feed for ultra-wide bandwidth quadruple-ridged flared horn (QRFH) antennas is presented. The circuit is synthesised by only 3 unknowns and achieves an accurate input impedance for a wide range of dimensions. This model allows fast synthesis of optimal feeding designs that would ensure the excitation of the fundamental mode at the input of Pa QRFH.
