A New Rotman Lens Power-Distribution and Phase-Shifting Network Design for a mmWave SatCom Phased Array Antenna Sytem

A new power-distribution and phase-shifting network design based on a Rotman lens for a SatCom phased-array antenna in the K- and Ka-band is presented. It reduces space con-sumption and meets all the requirements given in aerospace. The new design is presented together with a mechanical engineering model that is used for space-compliance tests. The functioning is proven by simulated and measured antenna patterns.
