Abstract


The design of a plane Archimedes spiral antenna is put forward. Compared with the traditional Archimedes antenna, the gain of low frequency is improved by adjusting shape and thickness of the absorber in the back cavity. Thus an Archimedean spiral antenna with the gain of 1.3dBi at the low frequency is designed, which bandwidth covers from 1GHz to 3GHz with return loss less than -10dB. Finally, the designed antenna is made, the results of the measurement fit well with the simulation ones.
