Wide-band MIMO Antenna for ISM / Bluetooth / Wi-Fi / WLAN Applications

EasyChair Preprint 5016

Abstract

An annular structure 2× 2 MIMO antenna with low mutual coupling is proposed to operate at 2.4 GHz WLAN band applications. This paper presents a multiple input multiple out antenna design with an overall size of 40x75x1.5mm^3.for WLAN applications. The proposed MIMO antenna is printed on a thin 1.5 mm FR4 substrate with the dielectric constant of 4.4 and loss tangent of 0.02.

 It is found that the newly designed MIMO antenna which combines the annular slot radiation patch and slotted ground plane with vertical strip   has the widest bandwidth and the best matching characteristic. The results indicate that the proposed receiving antenna performs well at LTE band with a wide bandwidth from 2.25 GHz to 3. GHz. The maximum efficiency of the proposed rectenna reaches 69% at 2.4 GHz.  An implanted I-shaped ground stub is placed between a pair of radiating element to achieve improved impedance bandwidth and isolation.  The proposed antenna covers a −10 dB operating band of 2.25 to 3 GHz with more than 30 dB isolation between a pair of elements.  The value of ECC < 0.0004, DG > 10.1, and current distribution 74.96%.
