Abstract
In this study, a lumped component based frequency reconfigurable multiple-input-multiple-output (MIMO)
receiving wire design is presented. The proposed antenna is composed of a planar structure in form of F-shaped together
with a slotted and defected ground structure for bandwidth and isolation enhancement. The MIMO antenna operates in six
frequencies upon the state of the four lumped element switches. The proposed receiving wire design exhibits a multiband
frequency reconfigurable characteristics from 1-7GHz with isolation of more than 14dB for the whole band, with efficiency
of about 75%. The MIMO antenna’s behavior in terms of ratio of square root of the sum of power reflected wave to the
incident wave (TARC), ECC and CCL are all within the acceptable limits. The design is suitable for personal
communication system (PCS), WIMAX and WLAN wireless applications.
