Dual-feed antenna array with integral comparison circuit for phase and amplitude calibration |
摘要 |
A two-element array antenna system includes a first antenna element and a second antenna element. A transmitting, receiving, and processing (TRP) system is coupled to the first and second antenna elements via, respectively, a single first transmission element and a single second transmission element. The first and second transmission elements have respective transmit-path and receive-path functionality. The TRP system is configured to determine an amplitude offset and phase offset associated with the transmit-path functionality of the first and second transmission elements, and, based on data obtained during the determination of amplitude offset and phase offset associated with the transmit-path functionality of the first and second transmission elements, determine an amplitude offset and phase offset associated with the receive-path functionality of the first and second transmission elements. |

1. A two-element array antenna system, comprising:
only a first antenna element and a second antenna element; a transmitting, receiving, and processing (TRP) system coupled to the first and second antenna elements, the TRP system being coupled to the first antenna element via a single first transmission element, the TRP system being coupled to the second antenna element via a single second transmission element, the first and second transmission elements having respective transmit-path and receive-path functionality; and a first circuit comprising a sampling element, the sampling element comprising one or more directional couplers electromagnetically coupled to the first transmission element and the second transmission element, the sampling element being configured to sample a first transmit signal from the first antenna element and a second transmit signal from the second antenna element, the first circuit further being configured to generate a first output signal based at least in part on the first transmit signal and the second transmit signal, wherein the TRP system is configured to:
receive, via at least one of the first transmission element and the second transmission element of the TRP system, the first output signal;determine, based on the first output signal, an amplitude offset and phase offset associated with the transmit-path functionality of the first and second transmission elements, andbased on data obtained during the determination of amplitude offset and phase offset associated with the transmit-path functionality of the first and second transmission elements, determine an amplitude offset and phase offset associated with the receive-path functionality of the first and second transmission elements. |
