The 4th Generation of mobile communications (4G) came with new challenges on the antenna bandwidth and on the front-end architecture of mobile phones. This letter proposes a novel architecture overcoming these challenges. It includes narrowband tunable antennas, co-designed with a tunable front rnd (FE). Simulations and measurements demonstrate the concept for low and high bands of the LTE frequency spectrum.
