Low SAR, Planar Monopole Antenna with Three Branch Lines for DVB, Mobile, and WLAN
In this paper, an open slot antenna fed by a u-shaped monopole is introduced. The slot antenna radiates in the range from 1.6 to 3.44GHz and from 3.8 to 5.7GHz. The slot is formed by an open ring of quarter wavelength at 900MHz. Thus, the ring acts both as a monopole at 900MHz and as a wideband slot radiator in the high frequency range. In order to serve the LTE 700MHz band, another monopole ring is added to the antenna to cover DVB-H and T-DMB for mobile broadcasting. The antenna size is 28x38x1.5 mm3.
