Abstract
An antenna structure serving as an emitter in a radar device with optimized isolation of signal comprises antenna array as the radiating element. The antenna array includes array units. Each array unit includes radiating units connected by a feeder. Radiation area of each radiating unit gradually decreases from a center of array unit to ends of array unit. A specified distance is defined between centers of adjacent radiating units along an extending direction of the feeder. The feeder transmits a current signal to the array units, the radiating unit emits a radar scanning beam based on the current signal.
