PATCH ANTENNA AND DUAL-BAND INTERLEAVED ARRAY WITH PASSIVE ELEMENT

This abstract first appeared for US patent application 18340770 titled 'PATCH ANTENNA AND DUAL-BAND INTERLEAVED ARRAY WITH PASSIVE ELEMENT



Original Abstract Submitted

A patch antenna array includes a plurality of high-band patch antennas configured to radiate at frequencies in a relatively higher frequency band; and a plurality of low-band patch antennas configured to radiate at frequencies in a relatively lower frequency band, the low-band patch antennas interleaved with the high-band patch antennas. Each low-band patch antenna includes: an active element; and a passive element comprising a metal ring with an outer edge and an inner edge, the inner edge defining an inner opening. A corresponding patch antenna includes an active rectangular patch element; and a passive element disposed above the active element with a metal ring defining an inner opening, wherein the passive element is disposed above the active element. The passive, metal ring elements can optimize the dual-band performance by controlling interference. Very narrow substrates can be enabled.
