Abstract :
This paper presents a matching method for a antenna element. The proposed antenna is comprised of a equiangular spiral antenna, Archimedean antenna and two stubs, which printed on a Rogers Duroid 5880 substrate with εr = 2.2 and a thickness of 1.52 mm. The matching problem between antenna and a diode is well solved. The proposed antenna, covering the frequencies in the range from 0.6 GHz to 10 GHz, can be easily extended to a rectenna array
