Description

technical field [0001] The invention belongs to antennas, in particular to a lumped element antenna. It belongs to the field of electronics and communication. Background technique [0002] In recent years, a series of researches on antennas have been carried out at home and abroad. In a specific frequency band, many achievements have been made, especially in WCDMA technology. Antennas play an important role in systems such as microwave communication, electronic countermeasures, microwave measurement, and phased radar components. For example, in the base station and mobile system of mobile communication, the antenna is used as a common device connecting the receiving and transmitting circuits with the antenna; the purpose of improving system stability and reliability. [0003] However, due to the problem of its circuit structure, the traditional antenna is extremely sensitive to temperature, and its applicability is greatly limited. The present invention can effectively s...
