The objective of this thesis is to determine and analyze the characteristics of ultra wideband antennas for personal communication systems. For this purpose a diamond dipole antenna, an ultra wideband antenna designed by Time Domain Corp, is studied and various parameters, like Sil and the VSWR of the antenna are calculated. These parameters are determined by simulating the antenna using the XFDTD software and the MultiStrip program. The results thus obtained are validated by measurements on the network analyzer using the antenna model. A bowtie antenna with the same dimensions as the diamond dipole antenna is suggested and performance of these two antennas is compared. Subsequently a new geometry of bowtie antenna is suggested and the effect of varying the cone half angle on the VSWR and Sil parameters of the antenna is investigated. Further, a comparison is made between the new model of the bowtie antenna and the diamond dipole antenna. Towards the end, a new ultra wideband antenna using a bowtie is suggested.
