The antenna shown in Fig. 2 will produce a line f due to the movement of the sleeve like a waveguide. In particular, if the surroundings of the sleeve are required to have a variable operating frequency 'integral multiple of the wavelength, a ring-mode resonance can be set, which is characterized by at least a voltage dipole across the cavity opening in diameter. The helical element MA with a radial connection ship, bribe and transmission line 20, 22 is used as a -feed line 'to impart a rotational component to the dipole, so that it rotates about the central axis Α2Α.

The antenna-constructed electrical micro-strip package of Hongkong Imbefley Communications Consulting Co., Ltd.) reveals that the ring spectrum vibration is characterized by the maximum current density at the relative position "H" not only at the ring 24r of the sleeve, but also extends downward To the inner surface of the sleeve towards the lateral conductor layer% or bottom wall, as shown in Figure 4 (a). The dotted line in Figure 4 indicates the distribution of the fixed current density on the inner surface of the sleeve. The pattern of (A) and Figure 4 corresponds to the required variable operating frequency. When the surrounding area is actually equal to the wavelength Ag Occurs from time to time. Furthermore, when the guiding wavelength is an integer multiple around the ring, there is ring resonance, so that, for example, opposite maximum current and voltage pairs appear, which are spaced around the ring gauge and the inner surface of the sleeve 24. Therefore, in the general example, the maximum current of one or more diameters relative to the vertical shot (as shown in Figure 4) may exist under the operating frequency. 12-
