This paper describes a modular active antenna for satellite communications in the K/Ka band. The application is thought for mobile satellite communications and internet links, mainly for commercial airplanes. The impossibility to build full active antennas including amplifiers in all the elements leads to a modular semi active antenna. Here the module is a small subarray with complete phase control in the elements. The phase control is made with ad-hoc phase shifters giving the minimum losses. Only two-bit control has been selected to perform phase shifters associated to a circular polarization radiating element. The feeding network has been selected to give the minimum losses and special ridge waveguide has been design to perform the network. The radiating element is a circular double patch fed in two points to obtain circular polarization. All the prototype has been designed in LTCC substrate to perform the minimum losses and stable structure | |
