This paper presents an antenna with sensing capabilities using shift frequency to determine the temperature. This antenna is made up of a dipole operating at 1.5 GHz and a mercury thermometer operating between 10 and 53 degree Celsius. The dipole is used to excite the thermometer as an equivalent metallic dipole by coupling. The changes in physical dimensions of the mercury dipole due to temperature changing involve a frequency shift of the resonant frequency. The measured results show this frequency variation as a function of the temperature.
