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.

A tire pressure detecting valve stem has a case, a body and a tire pressure detector. The case is rectangular and has an inner surface. The body is a valve stem and is integrally and transversely mounted on the case and has an inner section and a center pin. The inner section is integrally mounted in the case. The center pin is conductive, is coaxially mounted in the inner section and protrudes from the inner surface of the case. The tire pressure detector corresponds to and is mounted on the inner surface and is electronically connected to the center pin. Because the case is integrally and compactly mounted on the inner section of the body, the case will be mounted on and stay close to a rim when the body is mounted through the rim.
