Adjustable Input Impedance Dipole

In this paper, a novel dipole design with an adjustable input impedance is presented. The proposed dipole is designed to have additional arms attached at the edges of the feeding gap for the purpose of controlling the input impedance. Varying the dimensions of the two arms enables the tuning of the input impedance. This design is highly suitable for systems where the input impedance of the antenna needs to be directly matched to the input impedance of a receiving circuit. The proposed antenna eliminates the need for matching circuits which may deteriorate the efficiency of the entire system
