QFHA Antennas for Satellite Radio and Mobile Phone Applications

Presentation of a specific quadrifilar helical antenna design for satellite radios, along with a planar design for an integrated BFN90 beam forming network
Quadrifilar helical antennas (QFHA) are one of the best candidates to provide a high gain, shaped beam with excellent circular polarization axial ratio for satellite radio and mobile satellite phone systems. One of the most compelling reasons to use these antennas for digital radio and mobile satellite systems is...
