Surface-mounted UWB handset antenna with small envelope volume

This work investigates the effects of component population on the performance of miniature handset antennas operating in the UWB bandgroups 3 and 6. Two antennas are evaluated, a small ceramic block PIFA and a miniature planar monopole, both of height 4 mm. The antennas are located on a standard mobile phone board and provide efficiencies greater than 50% over the 6.3 - 9 GHz band.
