| 摘 要： | IntroductionA triangular patch antenna's major weaknessis its intrinsic narrow bandwidth.Some techniqueshave been suggested for widening its bandwidthsuch as the employmentof a thicker substrate witha coaxial feed1] ,which will limit the achievablebandwidth due to the increased inductance of thelonger probe. Recently a novel feeding approachemploying an L- shaped probe has been devel-oped2 ] ,butno numerical analysis has been provid-ed.Physically this L- shaped probe introduces a ca-pacitan…

| Abstract: | A single layer triangular patch antenna fed by an L-shaped probe was investigated numerically by using FDTD (Finite Difference Time Domain) method. It achieves >40% impedance bandwidth (VSWR<2) and stable radiation pattern across the passband. The triangular patch antenna with two orientations of L-shaped probe has almost the same characteristics, such as impedance bandwidth and radiation pattern. The bandwidth vs feeding position was also investigated, the broadband characteristic can be observed when the feeding position is only in a small segment along the centerline. |
