Design of Compact Two-Element MIMO F-Antenna

In this paper, transmitter and receiver is designed using multiple antenna and is called as MIMO (multiple-input and multiple-output) antenna. For minimizing the error and optimizing the data speed using MIMO antenna at each end of the communication circuit. MIMO antenna is used for improving the link quality, between transmitter and receiver. The size of this antenna is 20 mm × 40 mm. The resonant frequency is 3.73 and 4.5 GHz in single F-antenna and the gain is less than 2 dB, which is further increased to 2.3 dB by using array antenna. The return loss of single antenna is −25 dB which increases up to −40 dB. It gives dual-frequency when designed on Computer Simulation Technology (CST). It has compact structure and dual-frequency which is used in different applications. The shape of this antenna is F that is why it is called as F-antenna. There is also one decoupling element between two antennas.
