Abstract

A small-size tablet device antenna with three wide operating bands of 698~960 MHz, 1710~2690 MHz and 3400~3800 MHz for the LTE operation is presented. The antenna occupies a small ground clearance of 10 × 30 mm² and has a thin thickness of 3 mm in the tablet device. The antenna comprises three radiating branches and a circuit-based wideband feed structure formed by the integrated matching network. The integrated matching network can cause dual-resonance of the three resonant modes contributed by the three branches, thereby greatly enhancing the bandwidths to cover the desired bands. Results are presented and discussed.
