DUAL-BAND PHASED ARRAY ANTENNA WITH BUILT-IN GRATING LOBE MITIGATION

摘要

Dual-Band phased array antenna with built-in grating lobe mitigation comprising:
- an array of radiating elements (110) capable of working at both bands and arranged at distances small enough, avoiding grating lobes with respect to the lower band within the desired field of view,
- whereas the radiating elements are arranged in planar subarrays (100) which can be steered independently from each other, and
- each of the subarrays (100) has a different boresight normal vector, so that grating lobes in the upper band being mitigated.
