This paper introduces an idea of a 6-ridge horn antenna for spherical near-field antenna measurements. It is shown that, as opposed to a quad-ridge horn antenna, the 6-ridge horn antenna gives, in theory, a possibility to achieve quasi-first-order characteristics for the antenna over a substantially wide frequency range provided a proper feeding can be realized.
