Abstract
In this paper, the performance variation of a planar circular monopole antenna is studied, when this antenna is fabricated to film type and installed in the space between case and PCB of UWB terminal. When the circular monopole part has the 'ㄷ' folded structure, the input impedance and return loss, bandwidth, radiation pattern of this antenna are simulated and measured. Then the performance variation is compared with conventional planar antenna. As the results, the folded type circular antenna is usable as a intenna of UWB communication terminal, because of the good return loss and radiation pattern performance in the 2.6 - 12 GHz including the UWB frequency band.
