arm shaping time-division long term evolution capacitor loading dual-band
To solve the problem of the multiple radiation element integration antennas which are widely used in the mobile communication system,a dual-band dipole antenna is designed and fabricated in this paper.Utilizing the method of shaped-arm,the main resonance bandwidth is broadened; utilizing extension and bending of the antenna arms,dual band is realized; utilizing capacitor loading technology,the shift of frequency is realized.The above design make the operating bands cover TD-LTE standard of domestic 4G mobile communications.Simulated and experimental results of the reflection coefficient(S11)of the antenna are in good agreement in 1.8 GHz~3.0 GHz.The frequency range with S11 of below -10 dB covers all the service bands of TD-LTE standard.Simulated and experimental results of radiation patterns at two resonance points are also in good agreement which accords with the radiation performance of dipole antennas.Besides,the antenna has a stable gain over its operating bands.
