Novel Ultrawide-band Miniature Antennas

Study of novel circular disc monopole ultrawide-band miniature antennas is presented in this paper. Based on the conventional circular disc monopole, two kinds of novel circular disc monopole ultrawide-band miniature antennas are proposed. The circular disc monopole is revolved or puckered. The improved antennas are not only favorable for satisfying ultrawide-band requirement but also advantageous in realizing the further miniaturization. Detailed analyses are conducted to determine the novel antennas´ properties. And the return loss, current distributions, radiation patterns and gain of the antennas are discussed. The novel antenna proposed in this paper is suitable for the wireless, satellite and mobile communication systems with good prospects.
