Summary:
Semi-circular monopole antennas have wideband characteristics and compact size when they are rounded cylindrically. And, disc circular monopole antennas also have wideband characteristics and simple structure. So it is expected that the frequency band of circular monopole antennas are as wide as that of semi-circular monopole antennas when they are rounded cylindrically. This paper describes wideband characteristics of rounded circular and semi-circular monopole antennas. Especially, the optimum antenna shape, the degree of roll and the characteristic impedance are studied.
