BASE STATION ANTENNA RADIATOR HAVING FUNCTION FOR SUPPRESSING UNWANTED RESONANCES
A base station antenna radiator comprises: a first balun substrate, on an upper surface of which a feed line, a first C-coupling member, and a first inductive filter line connected to the first C-coupling member, and on a lower surface of which a third C-coupling member opposite to the first C-coupl...

Zusammenfassung: | A base station antenna radiator comprises: a first balun substrate, on an upper surface of which a feed line, a first C-coupling member, and a first inductive filter line connected to the first C-coupling member, and on a lower surface of which a third C-coupling member opposite to the first C-coupling member and a third inductive filter line electrically connected to the first inductive filter line through a first via hole and connected to the third C-coupling member are formed, the first balun substrate being placed perpendicular to a reflector; a second balun substrate coupled orthogonally to the first balun substrate, and on which a metal pattern substantially identical to that of the first balun substrate is formed; and a radiating substrate disposed above the first and second balun substrates, placed parallel to the reflector, and on an upper surface of which at least one radiating patch is formed. |
