一种十字交叉折线型的开槽宽频带UC-EBG结构及其设计方法
Abstract:
本发明涉及一种十字交叉折线型(Cross Fold Line)的开槽宽频带共面紧凑型电磁帯隙(Uniplanar Compact Electromagnetic Band Gap，UC-EBG)结构及其设计方法，属于电磁传播与接收的技术领域。本发明设计的UC-EBG结构具有宽频带、帯隙可调的特点。CFL-UC-EBG结构同向反射帯隙为63-93.5GHz相对带宽为38.85％；基于相同的结构，本发明通过改变结构单元数目，当3个CFL-UC-EBG结构单元周期性排列时，得到了禁带帯隙为50-80GHz相对带宽为46.15％的UC-EBG结构。本发明设计的CFL-UC-EBG可广泛应用于60GHz高频微波天线中。
Abstract(English):

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.
