Pattern Reconfigurable Mimo Antenna
Radiation pattern reconfiguration is a new
technique for antenna design as it enables the antennas to adapt
to different propagation. Multi Input Multi Output (MIMO)
antennas are recently more focused in mobile communication.
In this paper, a novel dual feed pattern reconfigurable MIMO
antenna is designed without using switches. To implement the
design, a circular Defected Ground Structure (DGS) with
concentric split ring (SR) is employed beneath the signal plane.
The signal plane comprises of octagonal ring pattern with
orthogonal dual feed arrangement. The operation of the
antenna is well analyzed with its reflection coefficient and
radiation pattern. The proposed antenna is resonating at same
frequency with different radiation pattern. The prototype is
designed to be utilized in LTE700 and GSM900 bands
