A dual-port tunable intermodulation (IM) generator is reported. This IM generator employs a coupling network to distribute carrier waves and IM. The proposed coupling network is constructed by cascading four parallel-coupled directional couplers, while a Schottky diode is working as a tunable IM source. By adjusting the IM performance of diode using bias voltage and distributing IM along symmetrical...
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...
