This article presents design and simulation of a
new compact four-element dual-band MIMO frequency
reconfigurable antenna that can be reconfigured for
WiMAX and LTE applications. The antenna includes four
elements at the same FR4 substrate with an optimized
overall size of 65x65x1.6 mm3 and an optimized partial
GND plane of 30x11.125 mm2. The reconfiguration rate is
between 2.41 and 3.99 GHz that can cover the WiMAX and
LTE wireless devices by applying just one RF (PIN) switch
to change the operating frequency. The antenna operates
on the two states of the PIN diode under its two states ON
and OFF with (2.7 GHz, and 2.8 GHz) resonant frequencies
respectively. The proposed antenna produces acceptable
simulation results for the MIMO system by achieving gain
from (3-7.2) dBi, less than -14.5 dB coupling effect, less
than 0.28 envelope correlation coefficient, and diversity
gain range from 8.4-10.
