Spoke Top Antenna for Transient Radiation

By Julie A. LaComb
Progress In Electromagnetics Research Letters, Vol. 11, 1-9, 2009


When an antenna transmits a short pulse of energy such as used for ultra-wide band applications, the pulse gets distorted upon transmission. To examine the properties of pulse transmission it is helpful to analyze the system in the time domain versus the frequency domain. Presented is a spoke top antenna for transient radiation. The spokes reduce the reflection from the open end of the antenna significantly reducing the trailing pulses commonly seen in the time domain. Comparisons are made with a dipole antenna. Both analytical, modeled and experimental results are presented.
