Embodiment Construction

[0041] figure 1 and figure 2 Some examples of SFC curves are shown. figure 1 Graphs (1), (3) and (4) in , show 3 examples of SFC curves called SZ curves. For comparison, graph (2) shows a curve that does not belong to the SFC curve because it only includes 6 segments. figure 2 Graphs (7) and (8) in Fig. 1 show two other special examples of SFC curves formed by periodic repetitive motion, including SFC curve (1). It is important to note that these examples of SFC curves are not the same as periodic, curved non-SFC curves such as figure 2 Substantial difference between the curves shown in graph (5) and graph (6)). Although the curves (5) and (6) consist of more than 10 segments, in essence, they are still considered to be periodic along the straight line (horizontal direction) and to determine the periodic or repeating unit movement of less than 10 segments (graph The cycle in (5) only includes 4 segments, and the cycle in the curve (6) includes 9 segments), which violate...

Abstract

This invention relates to a new geometrical structure and defines its SFC geometric structure, which can be used in molding part antennas and reduces size of an antenna relative to the current technology or makes traditional antennas of the same size operate at even lower frequency with a given fixed size.

Description

[0001] This application is a divisional application of the Chinese patent application No. 00818542.5, the application date being January 19, 2000, and the invention title being "Space-Filling Miniature Antenna". technical field [0002] The present invention generally relates to novel antennas of reduced size according to a novel geometry, referred to as a space-filling curve (SFC), with a curved geometry. When the antenna can be installed in a space smaller than the operating wavelength, the antenna is called a compact antenna. More specifically, antennas are classified into small antennas with reference to the arcuate sphere. A curved sphere is an imaginary spherical surface with a radius equal to the operating wavelength divided by 2π; depending on the wavelength, when the antenna can be installed within the curved sphere, the antenna is called a small antenna. Background technique [0003] The present invention identifies a novel geometry, the Space Filling Curve (SFC) ...
