Abstract

A Ring shaped multiband fractal 2×2 MIMO antenna is proposed. The monopole antenna supports applications such as Bluetooth, GPS and PCS. The proposed antenna is fed with microstrip line feed. The antenna is designed with two different orientations 0° fractal ring antenna and 180° shifted fractal ring antenna. The antenna is simulated on 2D EM-simulator of ADS software. FR4 substrate is used and the overall size of the designed antenna is 70mm×45.3mm×1.6mm. The antenna is designed to operate for multiple frequencies with increase in gain, directivity, bandwidth and radiation efficiency. The 0 Fractal Ring configuration is better in terms of gain compared with 180 ring design.

Abstract

This paper proposes a compact planar ultra wideband (UWB) antenna is proposed which is applicable in the field of communication, radar and medical. The proposed antenna has a low profile structure, consisting of a modified radiating patch in Asscher shape with an octagonal slot. The optimized antenna is capable of being operated in frequency range of 2-14GHz band having good omnidirectional radiation pattern and high gain, which almost satisfies the requirements of UWB applications. The antenna system has a compact size of 30×28.5×1.6mm³. These features make the proposed UWB antenna a good candidate for communication, radar and medical applications.
