Base station antenna assembly and printed circuit board used in base station antennas

A base station antenna assembly, comprising:

• a grounded reflector;
• a grounded first housing positioned rearward of the reflector;
• a grounded second housing positioned rearward of the reflector;
• a first conductive wire including a first portion positioned inside the first housing and a second portion extending outside the first housing, the first portion of the first conductive wire being configured to form a first stripline transmission line with the first housing;
• a second conductive wire comprising a first portion positioned inside the second housing and a second portion extending outside the second housing, the first portion of the second electrically conductive wire being configured to form a second stripline transmission line with the second housing;
• and
• a feeder panel positioned in front of the reflector, the feeder panel including a dielectric substrate and a grounded conductor plane formed on a rear surface of the dielectric substrate, wherein
• a second portion of a first conductive wire passes through the reflector and the feeder panel and extends forward of the feeder panel,
• a second portion of a second conductive wire passes through the reflector and the feeder panel and extends forward of the feeder panel, and
• the conductor plane forms a gap between the second portion of the first conductive wire and the second portion of the second conductive wire.

A base station antenna assembly, comprising:

• a reflector configured to provide a ground plane;
• a first radiator positioned forward of the reflector, the first radiator being configured to send and receive electromagnetic radiation within a first frequency band;
• a second radiator, positioned forward of the reflector, the second radiator configured to transmit and receive electromagnetic radiation within a second frequency band, the second frequency band overlapping with a first frequency band within a third frequency band;
• a grounded first housing positioned rearward of the reflector;
• a grounded second housing positioned rearward of the reflector;
• a first conductive wire for feeding to a first radiator, including a first portion positioned inside the first housing and extending outside the first housing and through the reflector to a second portion forward of the reflector, the first conductive wire being configured to form a stripline transmission line with the first housing;
• a second conductive wire for feeding to a second radiator, including a first portion positioned inside the second housing and extending outside the second housing and through the reflector to a second portion forward of the reflector, the first portion of the second conductive wire being configured to form a second stripline transmission line with the second housing;
• and
• a decoupling unit positioned in front of the reflector and positioned between the second portion of the first conductive wire and the second portion of the second conductive wire, the decoupling unit being configured such that at least within a third frequency band decoupling between the second portion of the first conductive wire and the second portion of the second conductive wire.
