Abstract

A method for enabling confirmation of expected phase shifts of radio frequency (RF) signals emitted from respective elements of an antenna array, such as a phased array antenna used for providing directional RF signal radiation patterns needed for beam forming. As a RF signal transmitted via an antenna element of the antenna array is shifted, e.g., stepped, in phase, the resulting received RF signal is monitored. Following detection of a phase shift, a sample of the received RF signal is captured and stored, e.g., for subsequent analysis, such as comparison with one or more expected signal phase differences to characterize the directivity of the transmitted signal.

Description

Background technique [0001] The present invention relates to testing radio frequency (RF) signal transmitters designed to perform beamforming, and in particular to detecting phase shifts of RF signals transmitted from elements of an antenna array for comparison with expected signal phase differences. [0002] Many of today's electronic devices use wireless signal technology for connection and communication purposes. Because wireless devices transmit and receive electromagnetic energy, and because the operation of two or more wireless devices has the potential to interfere with each other in signal frequency and power spectral density, these devices and their wireless signal technology must comply with various wireless signal technology standards specification. [0003] In designing such wireless devices, engineers take extreme care to ensure that such devices will meet or exceed the stated standard specifications for each of the wireless signal technologies involved. In addi...
