Abstract the lens plays important role in the dielectric resonator antenna (DRA) for increasing the bandwidth and directivity. Also, the liquids like water and ethanol can be noticed for developing the DRA for THz application. In addition, the liquids are interesting because the level and quality of material can be used for designing reconfigurable antenna. For the THz spectrum, the liquids can be combined with antenna and microwave devices by Microfluidic technology. In this paper, the suggested antenna is used to enhance the various factors of the antenna and the filling ratio of the channels is noticed to provide reconfigurable antenna. The slot antenna with split ring resonator and meandered feed is used as the basic antenna to provide high Q-factor. Moreover, the results show that this novel structure can be used as sensor for material detecting which is used to recognize various types of liquids by determining the sensitivity of the sensor in the range of 0.5 to 1 THz. The proposed sensor is examined for pure water, ethanol and gasoline based on the 2nd order model of Debye.
