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...

The Development of Wide Angle Base Station Antennas from Arrays

Use of flat panel array base station antennas to produce wide angle beamwidths up to 120°
Phased array antennas are traditionally used to produce narrow beams from large apertures. In this mode of operation, every radiating element in the array is broadly co-phased. The radiation pattern of the antenna is then the product of both the individual radiating element characteristic pattern and the array factor....
