Abstract
A wideband elliptical bowtie impulse antenna is proposed and investigated in this paper. Simulated results reveal that it can achieve an impedance bandwidth of 141% for S11≤-10 dB, a broadside gain of 2.4-5.3 dB, and stable radiation pattern over the whole operating band. The measured reflection coefficient is less than -10 dB over the frequency from 1.30 to 6.65 GHz, and it agrees well with the simulated results. The characteristics of frequency-domain such as radiation pattern, phase center and time-domain behaviors are discussed. The antenna electrical dimension is 0.31λ0, where λ0 is the free-space wavelength at lower edge of the operating frequency band. Parameters are studied to optimize the antenna performance.
