A wheel unit antenna and corresponding wheel structure for a tire pressure monitoring system (TPMS), where the antenna is sized and oriented such that the entire wheel structure, including a tire, will act as a waveguide. The antenna may be non-resonant, in the form of a monopole antenna perpendicular to the ground plane. In addition, the antenna length is substantially shorter than a quarter wavelength, such as one tenth wavelength ([lambda]/10) or less.
本发明公开一种用于轮胎压力监测系统(TPMS)的车轮单元天线和相应的车轮结构,其中,天线被确定尺寸和定向成使得包括轮胎在内的整个车轮结构将充当波导。天线可以是非谐振的,呈垂直于接地平面的单极天线形式。此外,天线长度大大短于四分之一波长,例如为十分之一波长(λ/10)或更短。
