A pattern diversity antenna with decoupling ports for LTE mobile phone

Abstract

A dual-band antenna with pattern diversity for Long Term Evolution (LTE) is designed in this paper. The size of proposed diversity antenna is only 100 × 55 mm2 which is suitable for mobile phone. The structure is composed of two radiating element positioned close to each other with space less than 0.05 guided wavelengths at 790 MHz. A neutralization line is inserted between two ports to improve isolation which achieves 15 dB in each band. Different radiation patterns are available simultaneously, thereby producing diversity suitable for MIMO systems.
