Design and development of dipole antenna for lte application

Abstract

One of the simplest and widely used antennas is Dipole antenna with which Heinrich Hertz demonstrated the existence of radio waves in 1887. In the modern era of wireless communication, we need antennas which supports for wide bandwidth and high gain. Dipole antenna array yields the remarkable features of broad bandwidth, high gain and supporting 4G LTE technology in its design. Applications having space constraints require the size of the antenna to be compact and high in gain with good stability over the operating range of bandwidth.These requirements are fully satisfied by Dipole antenna. Radiation pattern of Dipole antenna is desirable in many applications such as mobile communications, radio and television receivers. It is very useful for the reception of balanced signals without losing the quality. In this research, a Series fed Two Dipole Antenna (STDA) array has been studied and analyzed. STDA are preferred in base station antenna elements due to its simple structure and wide bandwidth and stable gain. Broadband and dual band characteristics can be obtained by using series fed Dipole pairs. The operating frequency of the proposed antenna can be varied by varying the lengths of the dipole elements and the return loss can also be easily controlled by controlling the distance between the dipole elements. newline
