Abstract

This paper presents an elliptical dipole antenna with rectangular slot reflector for wideband applications. The proposed antenna is designed on the FR4 substrate, resulting in low profile, high gain, and low cost. The antenna composes of an elliptical dipole and a slot rectangular reflector on the same plane. The proposed antenna has been analyzed and simulated by using the CST software package. In order to confirm the results, implementation and measurement of the antenna have been realized. The measured S11 <; -10 dB covering a frequency range from 3 to 12 GHz with a relative bandwidth of 123.07 % and the pattern bandwidth from 3 to 6.5 GHz have been obtained. Also, the main lobe gain of 5.3 dB has been found.
