Abstract
Official abstract text for this publication.
An array antenna is provided. The array antenna includes at least one pair of interleaved TR antenna arrays in a continuous arraying direction, where the TX arrays and RX arrays of two adjacent TR antenna arrays are interleaved. This can effectively rectify discontinuousness of TX arrays and RX arrays in a discontinuous arraying direction in the prior art, and thereby reduce grating lobes or side lobes caused by discontinuous TX arrays and discontinuous RX arrays in an array antenna, so that performance of the array antenna improves.
First claim
Opening claim text (preview).
What is claimed is: 1. An array antenna, wherein the array antenna comprises at least one pair of interleaved transmit-receive (TR) antenna arrays in a continuous arraying direction, wherein the at least one pair of interleaved TR antenna arrays includes two adjacent TR antenna arrays comprising transmit antenna (TX) arrays and receive antenna (RX) arrays that are interleavingly disposed; wherein the array antenna comprises at least one row of interleaved TR antenna arrays in the continuous arraying direction, wherein the at least one row of interleaved TR antenna arrays comprises at least one pair of interleaved TR antenna arrays. 2. The array antenna according to claim 1 , wherein when the array antenna comprises at least two rows of interleaved TR antenna arrays in the continuous arraying direction. 3. The array antenna according to claim 2 , wherein arrangement manners for the at least two rows of interleaved TR antenna arrays are identical. 4. The array antenna according to claim 2 , wherein arrangement manners for the at least two rows of interleaved TR antenna arrays are different. 5. The array antenna according to claim 1 , wherein TR antenna arrays of the array antenna are arranged in an even arrangement manner. 6. The array antenna according to claim 1 , wherein in a discontinuous arraying direction of the array antenna, a quantity of TR antenna arrays changes in an ascending order from an outermost column of TR antenna arrays to a middle column of TR antenna arrays, so that the array antenna takes on tapered distribution. 7. The array antenna according to claim 6 , wherein the array antenna comprises at least one row of TR antenna arrays irregularly aligned with an adjacent row of TR antenna arrays.
