A neutralization line is internally added to a 770 MHz LTE-band miniature dual-antenna system to improve its antenna efficiency. The odd-mode antenna impedance simulations indicate that the position of the neutralization line along the radiating structure determines the operation frequency. Measurement results show that the line reduces the antenna coupling loss from-6 to-17 dB while improving the individual antenna efficiency from 42 to 65 percent at 770 MHz.
