ABSTRACT

The design and development of a 23 triangular patch fractal multiple input multiple output (MIMO) antenna with the improved gain and bandwidth is presented in this paper. The MIMO structure is framed by integrating the elements such as coplanar waveguide feed and triangular patch fractal antenna array. The combined element is designed and fabricated. The proposed antenna is designed using HFSS software and the antenna parameters are validated using Vector network analyzer (E5071C ENA). The comparison is made between the simulated and fabricated results. The results show that the proposed antenna can be able to yield minimum return loss, larger bandwidth and improved gain at the designed resonant frequency.
