Abstract
This paper shows a time domain analysis, using the FDTD method, of the Multi-Sector Monopole Yagi-Uda Array Antenna (MS-MPYA) mounted on a finite ground plane. The MS-MPYA has an interesting feature. That is, we can sharpen the beams using the adjacent array effect if we set metallic fins between the arrays so as to hide the excitors. Without the fins, undesired radiation causes beam division. To examine this mechanism, this paper provides FDTD results for three types of Multi Sector Monopole Yagi-Uda Antenna: without adjacent arrays, with adjacent arrays but without fines, and with arrays and fins. Experimental and MOM results confirm the accuracy of the FDTD model. The transient solution tells us that without the fins, the beams propagate in three directions. Adding the fins, however, delays the onset of reradiation from the adjacent arrays as well as reducing the level of reradiation which suppresses beam division.
