摘要
Using the array antenna receiving fire microwave radiation within the building, fire detection and warning. In this paper, a calculation to determine the microwave radiant intensity of fire and antenna radiation intensity were derived based on microwave fire detection theory. Combining with complex conditions of the building fires and detect directional, designed a 2 * 2 rectangular microstrip antenna array with the method of coaxial feed. The antenna not only uses the slotting technology to make its impedance matching and easy to adjust, also refer H feed network to increase the directional gain and make its performance to receive fire the needs of the microwave radiation. HFSS simulation results show that the antenna has good performance with high gain, good directions and low side lobe so that it can meet the needs of fire for detection in complex fire environment, some methods for warning threshold value and eliminate interference of the detector are put forward.
