Quad Band Handset Antenna for LTE MIMO and WLAN Application

Abstract EN

A compact quad band antenna for long-term evolution (LTE) MIMO and WLAN application in the handset is presented in this paper.

The proposed antenna comprises two symmetrical quarter wavelength radiating strips and a slotted ground plane.

On the ground plane, a T-shaped slot is cut from the bottom.

Two symmetrical P-shaped slots are etched at both sides of the ground plane.

The radiating strips and slots generate a lower resonant at 780 MHz and an upper resonant at 2.350 GHz to cover LTE 700 Band 14, LTE 2300, 2.4 GHz WLAN, and LTE 2500.

A novel isolation technique by placing a rectangular patch between the radiating strips is presented.

The rectangular patch creates a dedicated current path for each radiating strip.

The proposed antenna has high isolation of less than −18 dBi at LTE 2300, 2.4 GHz WLAN, and LTE 2500 band.
