2. A base station antenna, comprising:
an antenna; and
a phase shifter that comprises a printed circuit board that includes a dielectric substrate and a trace on the dielectric substrate, where the trace is configured to transmit signals,
wherein the dielectric substrate includes a first part covered by the trace and a second part not covered by the trace, where the second part includes at least one hollowed out area near the trace, and
wherein the trace is supported by at least one bar in the hollowed out area.
