Abstract   Design of a novel wideband microstrip triangular patch antenna was proposed, in which the dualband operation was realized by loading a pair of narrow slots paralleled to the side edges of the equilateral triangular patch. Furthermore, by embedding a pair of narrow slots paralleled to the bottom edge, a tunable frequency ratio of the two frequencies was achieved by simulation and broadband operation of the triangular microstrip antenna near its fundamental resonant mode was realized. The proposed antenna was fabricated and measured, the results show that the proposed antenna achieved a bandwidth (VSWR<2) of 4.46 times and a size reduction of 9.3% compared to the conventional one. The measurement results are in great agreement with the simulation results, which demonstrates its validity．

新型宽频带微带贴片天线的设计

提出了一种新颖的展宽三角形微带贴片天线工作频带的设计方法．通过在三角形微带贴片侧边附近加载与之平行的缝隙来实现双频工作,并添加一对平行于底边的缝隙使两个频点靠近,利用仿真软件进行优化,有效地展宽了贴片天线的频带．制作了实际的贴片天线,结果表明所设计天线的工作带宽(VSWR<2)是普通三角形微带天线的4.46倍,且天线尺寸与同频率的常规贴片天线相比缩小了9.3%．测量结果与仿真结果吻合,证明了所提方法的有效性．
