A 2x1 Dual Band MIMO Antenna using Partially Extended Ground for Wireless Applications

The paper proposed 2 × 1 MIMO antenna is designed for S band and C band applications. S-Band (2-4GHz) and C-Band (4-8 GHz) C band of microwaves spectrum, which can be used for Bluetooth, WLAN, WiMAX and other wireless services. The Antenna operating at the 2 resonant frequencies 2.37 GHz and 5.60 GHz. The proposed design uses different techniques like partial ground, Circular Slot in patch and Partially Extended Ground (PEG) on low cost FR4 dielectric substrate with loss tangent 0.02. The dimension of the proposed MIMO antenna is of the size 35.39 x 50.18 mm2 .The proposed MIMO covers 2.1-2.5 GHz and 5.4 -5.9 GHz frequency bands. A linearly polarized dual-band MIMO antenna resonate at 2.37 GHz and 5.60 GHz frequencies is connected to both ends of the partial ground to reduce mutual coupling between radiators. The mutual coupling is reduced using partially extended ground. The antenna parameters such as return loss, VSWR, Envelope Correlation Coefficient (ECC), Isolation and gain are in good agreement with the requirements. The designing and simulation have been performed using CST (Computer Simulation Technology).
