摘要: A tapered slot quadrifilar antenna for GPS receivers. The has a cylindrical dielectric body covered with conductive coating. Four helical slots are formed in the and extend around one half of its circumference to provide right hand circular polarization receiving signals. microstrip feed system is provided arranged create balanced currents along both sides each so that impedance transformation not adversely affected. Each narrow upper end wide lower progressively greater width from end.
