Abstract
An anti-interference antenna of a wireless tire pressure receiver has an insulating cable having a main casing and a sub-casing connected side by side with the main casing. The main casing has a power cable longitudinally mounted through the main casing. The sub-casing has an antenna longitudinally mounted through the sub-casing. As the antenna is individually sleeved by the insulating sub-casing, the antenna and the power cables are isolated to prevent from interfering with each other. Besides, the insulating cable further has at least one air channel longitudinally formed through the corresponding cable and mounted with a metal layer on an inner wall of the air channel, around the power cable, around each of power wires in the power cable, or around the power cable and the air channel, and filled with an EMI-shielding matter to further isolate the antenna and the power cables.
