Design Multi-band of LTE-Advanced Antenna with Multi-coupling Path Applications

The proposed multi-band of LTE (long term evolution) -Advanced Pro antenna by 4-resonant path consists of multi band folding and two non-feeding elements at 800MHz, 2.1GHz, 1.7GHz and 700MHz. The experimental achieves LTE-A Pro target efficiency and gain after optimized parameters, cabling loss, cabling length and multi-coupling path for US (United States) band and EU (European Union) band for laptop PC and mobile device applications.
