ABSTRACT:
A hexafilar slot antenna for GPS receivers. The antenna has a cylindrical dielectric body covered with a conductive coating. Six helical slots are formed in the antenna and extend around one half of its circumference to provide a right hand circular polarization for receiving GPS signals. A microstrip feed system is provided and is arranged to create balanced currents along both sides of each slot so that the impedance transformation is not adversely affected.
