Abstract
Multi-band antennas include one or more duplexers configured to provide isolation of non-linearities generated along a downlink path of RF signals transmitted from the multi-band antenna from an uplink path of RF signals received by the multi-band antenna.
Claims19
A base station antenna comprising:
- a first radio frequency (“RF”) input port that is configured to be coupled to a base station radio;
- a plurality of sub-arrays of radiating elements, each sub-array including at least one radiating element;
- at least one transmit phase shifter coupled between the first RF input port and the plurality of sub-arrays of radiating elements;
- at least one receive phase shifter coupled between the first RF input port and the plurality of sub-arrays of radiating elements,
- wherein the at least one receive phase shifter comprises at least one solid state phase shifter.

An antenna comprising:
- a radio frequency (“RF”) input port;
- a transmit phase shifter;
- a receive phase shifter;
- a radiating element;
- a first circuit element having a first port coupled to the transmit phase shifter, a second port coupled to the receive phase shifter and a third port coupled to the RF input port;
- and
- a second circuit element having a first port coupled to the transmit phase shifter, a second port coupled to the receive phase shifter and a third port coupled to the radiating element,
- wherein a common, transmission path that connects the third port of the first circuit element to the first RF input port is configured to pass both transmit and receive RF signals.
5 more elements
An antenna comprising:
- a first duplexer having a first transmit port, a first receive port and a first combined port that is coupled to a first radio frequency (“RF”) input of the antenna;
- a second duplexer having a second transmit port, a second receive port and a second combined port that is coupled to a second RF input of the antenna;
- a plurality of sub-arrays of radiating elements that each include at least one radiating element;
- a plurality of multi-band duplexers, wherein each multi-band duplexer is coupled between a respective one of the sub-arrays of radiating elements and each of the first transmit port, the first receive port, the second transmit port, and the second receive port.
