一种基于U形槽和L型寄生条带的超宽带天线
摘要：
本发明涉及属于超宽带天线技术领域，尤其是一种基于U形槽和L型寄生条带的超宽带天线，包括介质基板、接地板、辐射贴片、微带馈线、同轴电缆和两个寄生条带，所述同轴电缆设置在介质基板一侧，所述接地板紧贴所述介质基板的下表面，所述辐射贴片上嵌入有U形槽，辐射贴片紧贴所述介质基板的上表面，所述微带馈线位于所述介质基板上表面，微带馈线一端连接辐射贴片、另一端连接所述同轴电缆的内导体，所述寄生条带为L型寄生条带，两个寄生条带设置在介质基板上表面，并对称位于所述微带馈线两侧。本发明具有结构紧凑、简单、易于制造的优点，实现了在3-11.1GHz频带范围内良好的阻抗特性、辐射方向特性。
摘要（英）：

>The invention relates to the technical field of a UWB (ultra wide band) antenna, and especially relates to a UWB (ultra wide band) antenna based on a U-shaped groove and L-shaped parasitic strips. The UWB antenna comprises a medium substrate, a grounding plate, a radiation patch, a microstrip feed line, a coaxial cable and two parasitic strips; and the coaxial cable is disposed on one side of the medium substrate, the grounding plate is tightly attached to the lower surface of the medium substrate, the U-shaped groove is embedded in the radiation patch, the radiation patch is tightly attached to the upper surface of the medium substrate, the microstrip feed line is located on the upper surface of the medium substrate, one end of the microstrip feed line is connected with the radiation patch, the other end of the microstrip feed line is connected with an inner conductor of the coaxial cable, the parasitic strips are the L-shaped parasitic strips, and the two parasitic strips are disposed on the upper surface of the medium substrate and are symmetrically located on two sides of the microstrip feed line. The UWB antenna has the advantages of compact and simple structure and ease of manufacture, and achieves a good impedance characteristic and a good radiation direction characteristic in a 3-11.1GHz frequency band scope.
