In-situ probes for patch antenna array calibration
2011
International journal of microwave and wireless technologies
Preserved Fulltext
A novel calibration network for patch antennas is proposed. We introduce magnetically coupled in-situ probes, which excite the fundamental patch mode. In that way, finite array effects and mutual coupling can be detected, providing the opportunity for online calibration. The specific advantages of the approach are demonstrated for linearly polarized patch antennas. Measurement results of a single patch with the integrated probes agree with simulation.
