This paper presents three different types of ultra-wideband (UWB) antennas for RF micro-radar applications in range of 1-3 GHz and discusses performance characteristics of each antenna. The electromagnetic radiation properties of antennas are analyzed based on their gain, bandwidth, voltage standing wave ratio (VSWR), conductivity, and form and size factors. In addition, the performance of each antenna is investigated with different feed line configuration to determine influence of feed line configuration upon the performance of each UWB antenna. The antennas were modeled using electromagnetic simulation software, FEKO. The software simulates the performance of each antenna via Method of Moment (MoM) technique that is a powerful method for analysis of electromagnetic radiation characteristics of RF antennas. This paper presents the simulation-based performance comparison of the three selected UWB antennas under the same operational bandwidth.
