Problems solved by technology
For example, test techniques that involve mechanical manipulation (e.g., movement or rotation) of the phased antenna array or probe antenna under test between various test steps (or experiments) may result in Test errors due to measurement errors (for example, errors in angle or distance measurements)

The invention provides an antenna array test circuit, a phased antenna array and a method for testing the same. The antenna array testing circuit can include a circuitry including a plurality of memory registers, a testing sequence generation logic, and a testing control logic. The memory registers can store, for each antenna element of a plurality of antenna elements of the phased antenna array,a corresponding antenna element ID. The memory registers can store a testing step ID indicative of a testing step of a sequence of testing steps. The testing sequence generation logic can determine, for each antenna element of the phased antenna array, using the corresponding antenna element ID and the testing step ID, a corresponding testing signal indicative of a testing state of the antenna element during the testing step. The testing control logic can cause each antenna element the phased antenna array to be configured according to the corresponding testing signal during the testing step.
Description
[0001] related application [0002] This application claims priority to U.S. Provisional Application No. 62 / 725,857, filed August 31, 2018, entitled "EMBEDDED ANTENNA ARRAY METROLOGY SYSTEMS AND METHODS," which is incorporated herein by reference in its entirety. Background technique [0003] Antennas produced for cost-sensitive applications often require testing and characterization before they can be used. Testing of an antenna is important to provide accurate measurements of the antenna's performance parameters. It is very common and frequent for antennas not to perform as expected or theoretically expected, especially when designed to minimize production costs. Thus, antenna testing serves to measure or evaluate actual performance metrics or parameters of the antenna prior to field use. Performance metrics measured during testing can be used to calibrate test antennas prior to (or during) deployment. [0004] For phased antenna arrays, performance parameters measured du...
