LTE band capacitive coupling element antenna for smart phone devices

In this work, a capacitive coupling elements antenna is proposed for handset devices. A dual-band matching network is employed to provide matching in the two LTE bands, Primary advantages of this antenna configuration include small sizes, simple structure, low cost, good radiation efficiencies and easy antenna tuning. The mechanisms for achieving low and high band matching at the same time are explained. The fabricated prototype validates its broad band and good radiation features. The proposed antenna configuration can be transport to other mobile platforms with little efforts.
