Hemispherical coverage
WebA Quadrifilar Helical Antenna with parasitic helical strips for circular polarization. The mutual coupling effect between the grounded helical strips and the feeding helical arms provides a good impedance match and wider hemispherical coverage. The impedance bandwidth corresponding to VSWR < 2 is 200 MHz, from 2.28 GHz to 2.48 GHz.
