Building a Quadrifilar Helix Antenna for Undergraduate ...
rish.kyoto-u.ac.jpthe extremly effective and efficient Quadrifilar Helix Antenna. The Quadrifilar Helix Antenna (QHA) is a simple and inexpensive solution to the problem of non-geosynchronous satellite research. This antenna is unique in its simplicity of design and powerful performance compared with standard directional receivers. Once relatively
RF design considerations for u-blox GNSS receivers
www.u-blox.comAnother style is the quadrifilar helix antenna. The actual geometric size depends on the dielectric that fills the space between the active parts of the antenna. If the antenna is only loaded with air it will be comparatively large (60 mm length and 45 mm diameter), high dielectric constant
