摘　　要：该文提出一种新颖的X形微带缝隙天线设计,缝隙的四角各有一个直角三角形补充缝,缝隙单元由基片另一侧面的箭头形微带线馈电.这种天线具有宽带特性和两维对称的特性且易于加工.文中给出了阻抗和方向图的计算结果,并给出实测结果.计算与实测结果吻合较好,实测的-10dB反射损失带宽达到21%左右.A novel X-shaped slot antenna with four complementary right-triangle slots at each corner is presented. An arrow-shaped microstrip line printed on the back of the substrate is used to feed the slot element. The antenna is of broadband and 2D symmetry characteristics, and easy to fabricate. Numerical results of the impedance and radiation patterns are described and an experimental result is (given.) The numerical result is in good agreement with the experiment. The measured -10 dB return loss bandwidth is up to 21%.
