Dual-band cross-polarized 5G mm-wave phased array antenna
Abstract:
A dual-band cross-polarized antenna includes first and second metal layers defining respective first and second driven patches configured to radiate at different frequencies, first and second feed pins connecting a first feed line to the first driven patch at respective first and second feed points thereof associated with orthogonal polarizations, and third and fourth feed pins connecting a second feed line to the second driven patch at first and second feed points thereof associated with orthogonal polarizations. The third feed pin extends through a first hole in the first driven patch to capacitively couple the third feed pin to the first driven patch. The fourth feed pin extends through a second hole in the first driven patch to capacitively couple the fourth feed pin to the first driven patch. Two or more antenna elements are arranged as a phased array antenna and packaged as an antenna module.
