Wideband Fork-shaped MIMO Antenna for Modern Wireless Communication

In this paper, a microstrip fork-shape MIMO antenna for modern wireless communication is proposed. The simulated results of the proposed antenna exhibits better frequency response within wideband frequency range. The obtained frequency bandwidth of the proposed antenna is 2.93 GHz (7.42 GHz-10.36 GHz) with a return loss of -44 dB at resonance. The suggested structure antenna is implemented in Rogers Ro3003 (lossy) substrate and having a dimension of (28.80×28.80 mm) and a thickness of 1.54 mm. Based on the results that obtained using CST microwave studio, it is noted that the reflection coefficient (S11) < -10 dB over a wide range of frequencies and has better isolation between the antenna elements which reached < -45 dB.
