Abstract :
An impedance transforming balun feeder system has been devised for low-gain antennas such as quadrifilar helices and spirals, consisting of four coaxial cables and a microstrip circuit. The arrangement allows physically orthogonal `balanced pair´ outputs with quadrature phasing, in space limited configurations
