摘要： Systems and methods of testing active digital radio antennas are presented. Systems and methods can test the active digital radio antenna functioning as both a radio and as an antenna and can test both the transmit and receive performance of the antenna. An electromagnetic probe can scan the antenna to perform the testing and couple to the elements of the antenna using radio frequency signals propagated in the air, as opposed to direct cabling.

摘要： 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.

摘要： 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.

摘要： In one embodiment, an antenna system has a plurality of antenna paths (116) and a calibration circuit. Each of the antenna paths has a transceiver (108) and an antenna element (114). The calibration circuit has (i) a calibration transceiver (216) and a different coupler (210) coupled to each antenna path. The couplers are connected in series with one another and with the calibration transceiver. Connecting the couplers in series, rather than in parallel, reduces the amount of cabling needed and the need for a combiner/splitter or switch matrix between the couplers and the calibration transceiver, thereby reducing the cost, volume, and/or weight associated with the calibration circuit.
