Abstract

In this paper, a new antenna is presented which has an application in cellular telecommunication systems. The designed antenna works at the frequency range of 1900-2600 MHz which is able to cover 2G, 3G and 4G (LTE) services of the cellular telecommunication. In this paper, the micro-strip structure has been used to design the antenna. The shape of the patches is triangular where a peripheral ring has been employed around the patches. A number of slots have been used over patch to increase the antenna efficiency. The obtained bandwidth for VSWR<2 is 56%. The antenna gain has been obtained within the frequency range of above 15 dB performance. The compressed dimensions, having two orthogonal polarization and simple antenna feed are considered as the advantages of the designed antenna.
