1. An antenna assembly comprising:
- a curved printed circuit board (PCB) comprising a first side and a second side;
a first antenna structure disposed on the first side of the curved PCB and configured to provide radio coverage for a first set of frequency bands;
a second antenna structure disposed on the first side of the curved PCB and configured to provide radio coverage for a second set of frequency bands; and
a third antenna structure disposed on the first side of the curved PCB and configured to provide radio coverage for a third set of frequency bands; and
wherein the curved printed circuit board is positioned between a spacer and a cover of a nozzle cap, wherein the spacer, the curved printed circuit board, and the cover extend around a curved surface of the nozzle cap, and wherein the curved printed circuit board and the spacer are positioned within an antenna cavity defined between the cover and the curved surface of the nozzle cap.
