Claim:
1. A broadband slot-coupled stacked patch radiating element comprising: a low-band resonator mounted to a face of an antenna reflector, wherein the low-band resonator comprises cross-slots, and wherein the low-band resonator is configured to radiate at a Universal Mobile Telecommunications System (UMTS) band that includes radio frequencies between 1.71 gigahertz (GHz) and 2.17 GHz; a mid-band radiating patch, wherein the low-band resonator is positioned between the mid-band radiating patch and the antenna reflector; a high-band radiating patch, wherein the mid-band radiating patch is positioned between the high-band radiating patch and the low-band resonator, wherein the high-band radiating patch is configured to radiate in a long term evolution (LTE) band that includes radio frequencies between 2.49 GHz and 2.69 GHz, and wherein the mid-band radiating patch is configured to resonate at inter-band frequencies between 2.17 GHz and 2.49 GHz; and a central feed assembly extending through an opening in the low-band resonator, the central feed assembly including feed pins that extend directly through the cross-slots in the low-band resonator and provide RF power to the high-band radiating patch and the mid-band radiating patch.
