Focal distance reduction of transmit-array antennas using multiple feeds

Abstract : The reduction of the focal distance of transmit-array antennas using multiple feeds is investigated theoretically and through full-wave simulations. A theoretical model of multiplefeed transmit-arrays is derived using analytic formulas; it shows that the focal distance can be divided by a factor of two using a quadruple-feed configuration. The theoretical results are validated through full-wave simulations for two transmit-arrays operating in the 60-GHz band.
