Embodiment Construction

[0015] The following structural drawings and embodiments further illustrate the present invention.

[0016] As shown in Figure 3.

[0017] A kind of Yagi reconfigurable fractal antenna is composed of an upper layer antenna assembly 1-1 (as shown in Figure 1) and a lower layer antenna assembly 1-2 (as shown in Figure 2) with the same structure, and the two are arranged in a space vertical state, That is, a group of triangular metal sheets 1 and 2 in the upper antenna assembly 1-1 and a group of triangular metal sheets in the lower antenna assembly 1-2 are spatially vertical. Both the upper antenna assembly 1-1 and the lower antenna assembly 1-2 are composed of two triangular metal sheets 1, 2, two V-shaped passive patch vibrators 3, 4, and two linear passive patch vibrators on the substrate. 5, 6 and microwave switches 7, 8, 9, 10, 11 (which can be realized by transistor switches or common micro-electromechanical switches MEMS), and they form a Yagi-like antenna structure. Am...

Abstract

The disclosed reconfigurable quasi-Yagi fractal antenna includes two layer antenna components (1-1, 1-2) with same structure. Wherein, every layer antenna component comprises: two triangular metal plates (1, 2) with opposite vertex on base, two V-shaped passive paster oscillators (3, 4) on side of plates (1, 2), two straight-line passive paster oscillators (5, 6) symmetrical set on outboard of oscillators (3, 4), and five microwave switches (7~11). This invention has well electric property.

Description

technical field [0001] The present invention relates to an antenna, especially an antenna designed based on the Sierpinski fractal principle, which is widely used in wireless communication, radar and other antennas that require simultaneous reconfigurability of operating frequency and pattern, specifically a Yagi-like reconfigurable Fractal Antenna. Background technique [0002] In recent years, antennas with simultaneous reconfigurable frequency and pattern are considered to be the development of electronic equipment in the direction of multi-function, and the need to install multiple antennas brings a series of problems such as large size, heavy weight, and poor electromagnetic compatibility. An optimal solution to the problem. At present, researchers have designed this type of antenna, the most typical of which is G.H.Hoff et al. in the literature "A novel radiation pattern and frequency reconfigurable single turn square spiral microstrip antenna" (IEEE Microwave and Wir...
