De stroomamplitudes van de voedingsuiteinden van de vier armen zijn gelijk, terwijl de fasen 90° van elkaar verschillen. Dit resulteert in een cardioïde stralingspatroon, een goede front-to-back-verhouding en uitstekende breedstralende circulaire polarisatie. Deze antenne is zeer geschikt als ontvangstantenne voor satellietpositioneringssystemen.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eAntenneparameters:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eAntenne-impedantie: 50
