Base station antennas are provided herein. A base station antenna includes one or more vertical columns of low-band radiating elements configured to transmit RF signals in a first frequency band. The base station antenna also includes a plurality of vertical columns of high-band radiating elements configured to transmit RF signals in a second frequency band that is higher than the first frequency band. The vertical columns of high-band radiating elements extend in parallel with the one or more vertical columns of low-band radiating elements in a vertical direction.

Multi-band base station antennas having interleaved arrays

A base station antenna includes a first set of radiating elements that are configured to generate a first antenna beam that has a first peanut-shaped antenna pattern in an azimuth plane and a second set of radiating elements that are configured to generate a second antenna beam that has a second peanut-shaped antenna pattern in the azimuth plane. A longitudinal axis of the first peanut-shaped antenna pattern in the azimuth plane is rotated approximately ninety degrees from a longitudinal axis of the second peanut-shaped antenna pattern in the azimuth plane.

Small cell antennas suitable for MIMO operation

A phased array antenna includes a first transceiver, a plurality of first radiating elements that are arranged in a first linear array, a first feed network electrically interposed between the first radiating elements and the first transceiver, and a first switch that is coupled along the first feed network, where a state of the first switch is selectable to adjust a number of the first radiating elements that are electrically connected to the first transceiver.

Phased array antennas having switched elevation beamwidths and related methods

A stacked patch radiating element includes a dielectric substrate, a ground plane on a first surface of the dielectric substrate, a patch radiator on a second surface of the dielectric substrate, a feed that is configured to connect the patch radiator to a transmission line, a solder layer on the patch radiator opposite the dielectric substrate, and a parasitic radiating element on the solder layer opposite the patch radiator. The parasitic radiating element includes a metal layer on the solder, a parasitic radiator dielectric substrate on the first metal layer opposite the solder, and a parasitic radiator on the parasitic radiator dielectric substrate opposite the first metal layer.

Aspects of the present disclosure may be directed to a wrap-around antenna capable of being wrapped around a support structure to provide antenna patterns for a communication system. Such an assembly may be aesthetically pleasing and, because the antenna assembly allows for radiation away from the support structure, scattering effects due to interference from the support structure may be eliminated.

Wrap around antenna

A phased array antenna includes a panel, a plurality of feed boards on the panel, each of the feed boards including at least one radiating element, a base-level adjustable phase shifter including a plurality of outputs, a first feed board adjustable phase shifter mounted on a first of the feed boards and a first cable that forms a transmission path between a first of the outputs of the base-level adjustable phase shifter and the first feed board.

Phased array antennas having multi-level phase shifters

A method of fabricating a monolithic feedboard assembly for a base station antenna, the method comprises injection molding a unitary frame that includes a feedboard section and at least one radiating element section and then selectively depositing metal on the unitary frame to form radio frequency transmission lines and radiators on the unitary frame to provide the monolithic feedboard assembly.

Monolithic radiating elements and feedboard assemblies for base station antennas formed via laser direct structuring and other selective metallization techniques

A feed network for use with an antenna array includes at least first and second RF inputs, a combiner network and a beamforming network. In some examples, additional RF inputs are provided. Each RF input corresponds to a sub-band. The first RF input for a first sub-band signal is coupled to a first sub-band parameter control; the second RF input for the second sub-band signal is coupled to a second sub-band parameter control. The combiner network is coupled to the first sub-band parameter control and to the second sub-band parameter control. The combiner network also has at least one output comprising a combination of the first sub-band signal and the second sub-band signal. The beamforming network is coupled to the combiner network and has a plurality of RF outputs. The first and second sub-band parameter controls are independently adjustable. In one example, the beamforming network comprises a Butler matrix.

Shared antenna arrays with multiple independent tilt

A solderless test fixture, including a conductive base, a clamp, and a connector is described. The conductive base has at least one cable groove with a cable grounding portion. A clamp is mounted on the base and associated with the cable groove. A connector is associated with the cable groove and has a solderless center terminal aligned with the cable groove and an outer shield being mechanically and electrically connected to the base.

Solderless PIM test fixture

An antenna comprising a plurality of sub-arrays and methods and structure for restoring performance after a transceiver failure is provided. Each sub-array may include a power divider/combiner network, a first radiating element coupled to a first port of the power divider/combiner network, a second radiating element coupled to a second port of the power divider/combiner network, and a transceiver coupled to a third port of the power divider/combiner network. An adjustable power supply may be coupled to each transceiver, the adjustable power supply having current monitors to detect at least one failure state of a transceiver, and a power compensation mode to increase absolute power to a transceiver in a non-failed state. The adjustable power supply provides a first voltage in normal operation and a second voltage, where the second voltage is higher than the first voltage in power compensation mode.

Active antenna sub-array structures

Antenna system having an antenna array with multiple sub-arrays, each having one or more antenna elements, is calibrated using a distributed calibration antenna element, such as a leaky coaxial cable, that spans across at least two and possibly all of the sub-arrays. To calibrate the transmit (TX) paths of the sub-arrays, TX calibration test signals are transmitted by the sub-arrays, captured by the distributed calibration element, and processed by a corresponding calibration radio. To calibrate the receive (RX) paths of the sub-arrays, an RX calibration test signal is generated by the calibration radio, transmitted by the distributed calibration element, captured by the sub-arrays, and processed by their corresponding radios. Cross-correlation between the calibration and captured signals is performed to derive the complex gain of each sub-array transmitter and receiver, which provides information for aligning the gain, phase, and delay of the different TX and RX paths of the antenna array.
