Internal Uniplanar Antenna for LTE/GSM/UMTS Operation in a Tablet Computer

IEEE Transactions on Antennas and Propagation


Issue Date:
2013


Abstract(summary):

With the use of an internal printed loop matching circuit, a small-size uniplanar antenna with eight-band LTE/GSM/UMTS operation in the tablet computer is proposed. The obtained impedance bandwidth across the operating bands can reach about 262/1610 MHz for the LTE/GSM/UMTS bands, respectively. Only with the antenna size of 40 x 15 x 0.8 mm(3), the proposed planar antenna has the compact operation with more than 30% antenna size reduction. Furthermore, the measured peak gains and antenna efficiencies are about 2.81/4.97 dBi and 79/87% for the LTE/GSM/UMTS bands, respectively.
