The dipole antenna or dipole aerial is one of the most important and commonly used types of RF antenna. It is widely used on its own, and it is also incorporated into many other RF antenna designs where it forms the driven element for the antenna. In this paper, an attempt has been made to investigate new half wave dipole antenna for GSM Applications. A dipole antenna approximately one-half wavelength long is the half wave dipole antenna. The antenna is made to resonate at the 1.995 GHz frequency. CST MWS Software is used for the simulation and design calculations of the half wave dipole antennas. The return loss, VSWR, Directivity, gain, radiation pattern are evaluated.
