A Broadband LTE/WWAN Antenna Design for Tablet PC

A broadband yet compact antenna design applicable to tablets and laptops is proposed. The antenna provides an extensive coverage for existing and upcoming mobile communication bands. Several band broadening and antenna miniaturization techniques were employed, including the use of a parasitic element, meandered structures, branched structures and a lump component. The proposed design is planar, compact and can be fabricated via printed circuit board technology. Measurement results exhibits broad resonant bandwidth. Nearly omni-directional patterns and reasonable radiation efficiency are observed.
