Abstract

A hexagonal shaped fractal Multiple input Multiple Output (MIMO) antenna resonates to six different frequencies is presented. A dumbbell structure with hexagon shaped defected ground structure (DGS) is created in the ground plane. Two antenna elements sharing a common ground plane are positioned orthogonal to each other for better isolation. The antenna is designed, fabricated using FR4 substrate with 1.6 mm thickness and tested experimentally. The antenna provides high peak gain of 8.69 dBi at 8.33 GHz. The multiband MIMO antenna resonates for the frequencies 1.9 GHz, 2.9 GHz, 3.2 GHz, 5.0 GHz, 5.6 GHz and 7.74 GHz. Mutual coupling is better than − 20 dB and the peak gain of the antenna ranges from 3.2 to 8.69 dBi. The designed orthogonal two element MIMO antenna is suitable for GSM, PCS, WLAN and Wi-MAX wireless applications. Simulation work is carried out by ADS tool and fabricated antenna is tested with vector network analyser.
