Modified Diamond Dipole Antenna For Ultra Wideband Communications Using Finite Difference Time Domain Method, Srinivas Desamsetty
FIU Electronic Theses and Dissertations
The aim of this thesis is to analyze and design ultra wideband antennas for personal communication devices using Finite Difference Time Domain (FDTD) method. Initially diamond dipole, an ultra wideband antenna is selected from the literature and analyzed. The shape of the diamond dipole is modified in such a way that the straight-line base of the two triangular arms (near the feed) is replaced with an arc. The resulting antenna is named as modified diamond dipole. Performance is observed by varying radius of curvature of base of triangular arms (for constant flare angle) and by varying flare angle (for constant …
