Embodiment Construction

[0036] The substantive characteristics of the present invention are further illustrated by the following specific embodiments:

[0037] (1) Design the CFL-UC-EBG structural unit. Design the slotted CFL-UC-EBG structural unit of cross-shaped zigzag line, where the periodic size of the structural unit is L, L1 is the inner width of the square ring, w1 is the width of the cross zigzag line, w2 is the slot spacing, and w3 is the microstrip line between the slots width.

[0038] (2) Determine the specific parameters through numerical modeling: the numerical modeling uses the reflection phase curve method and the suspended microstrip line model. First, the S-parameters of the CFL-UC-EBG structure were simulated using Rogers RO6010 dielectric substrate. By adjusting the thickness h of the dielectric substrate, the size L of the periodic unit, the inner width L1 of the square ring, the width w1 of the cross line, the spacing w2 between the grooves, and the width w3 of the microstrip...

Abstract

The invention relates to a cross fold line type slotted wideband uniplanar compact electromagnetic band gap UC-EBG structure and a design method thereof, and belongs to the electromagnetic transmitting and receiving technology field. The UC-EBG structure has characteristics of wide band and adjustable band gap. The parallel reflection band gap of the CFL-UC-EBG is in a range from 63 to 935 GHz, and the relative bandwidth is 38.85%. Based on the same structure, by changing a structure unit number, when three CFL-UC-EBG structure units are in a periodic arrangement, the UC-EBG structure having the forbidden band gap in a range from 50 to 80 GHz and the relative bandwidth of 46.15% is acquired. The CFL-UC-EBG provided by the invention is widely used for 60GHz high frequency microwave antennas.

Description

technical field [0001] The invention relates to a Cross Fold Line slotted broadband coplanar compact electromagnetic band gap (Uniplanar Compact Electromagnetic Band Gap, UC-EBG) structure and its design method, which belongs to the technology of electromagnetic transmission and reception field. Background technique [0002] 1. criss-cross polyline [0003] A criss-cross polyline is a variation of the cross-shaped intersection line. figure 1 A slotted wide-band coplanar compact electromagnetic bandgap structure of cross-cross zigzag type is given in . The EBG structure is composed of a slotted direction ring and a cross-hatch zigzag structure. The rotation angle of the cross-type structure is 45 degrees. The cross zigzag structure is used to increase the inductance of the EBG structure, thereby increasing the forbidden band width of the EBG. [0004] 2. Advantages of UC-EBG structure [0005] The EBG structure is a periodic electromagnetic structure with a frequency band...
