Reconfigurable MIMO Antenna for Integrated-Metal-Rimmed Smartphone Applications

A reconfigurable full-metal-rimmed MIMO antenna is designed and proposed for WWAN/LTE smartphones. This antenna consists of two centro-symmetrically distributed antenna elements and radiation structures using the unbroken metal rim in plastic casing. It can achieve a good isolation of more than 17dB...

description A reconfigurable full-metal-rimmed MIMO antenna is designed and proposed for WWAN/LTE smartphones. This antenna consists of two centro-symmetrically distributed antenna elements and radiation structures using the unbroken metal rim in plastic casing. It can achieve a good isolation of more than 17dB over the entire operation bands. Each antenna element occupies a small ground area of 30 &#x00D7; 6 mm<sup>2</sup>. The U-shaped feeding line provides a coupled feed and the antenna element generates four typical loop resonant modes. Using reconfigurable technique to combine these four resonant modes, this hepta-band MIMO antenna can satisfactory cover lower bands of GSM850/900 and higher bands of GSM1800/1900/ UMTS/LTE2300/2500. A prototype MIMO antenna was fabricated and the measured results of S-parameters, antenna efficiency and gain, envelope correlation coefficient, mean effective gain, and channel capacity are reported.
