Abstract
Base station antenna feed boards are provided. A base station antenna feed board includes a phase shifter and a hybrid radio frequency transmission line that is coupled to the phase shifter. The hybrid radio frequency transmission line includes a coplanar waveguide and a microstrip line. Related base station antennas are also provided.
Claims21
A base station antenna comprising:
- a printed circuit board (PCB) comprising a phase shifter and a plurality of radio frequency (RF) transmission lines that are coupled to the phase shifter;
- and
- a plurality of radiating elements that are on the PCB and coupled to the RF transmission lines,
- wherein a first of the RF transmission lines comprises a coplanar waveguide (CPW) that is coupled to a first of the radiating elements, and
- wherein a second of the radiating elements is coupled to a second of the RF transmission lines that is shorter than the first of the RF transmission lines.
A base station antenna comprising:
- a reflector comprising an opening therein;
- a printed circuit board (PCB) on the reflector and comprising a phase shifter and a plurality of radio frequency (RF) transmission lines that are coupled to the phase shifter;
- and
- a plurality of radiating elements that are on the PCB and coupled to the RF transmission lines,
- wherein a first of the RF transmission lines is coupled to a first of the radiating elements and comprises a coplanar waveguide (CPW) that overlaps the opening of the reflector.
A base station antenna feed board comprising a phase shifter and a hybrid radio frequency (RF) transmission line that is coupled to the phase shifter and includes a coplanar waveguide (CPW) and a microstrip line,
- wherein the hybrid RF transmission line is longer than any non-CPW RF transmission line of the base station antenna feed board.
