摘要：
An ultra-wide-band antenna based on a slotline feed structure, a bowtie horn, and a rolled edge termination was developed, analyzed and measured. Empirical data showed that its beamwidths and bandwidth are dependent on its physical dimensions which are easily controllable by an antenna designer. Measured patterns of models with various radiation properties are shown to substantiate these design rules. A flat plateau-like main beam, low voltage standing-wave ratio (VSWR), the ability to produce both wide (60-degrees) and narrow (30-degrees) haff-power beamwidths, low sidelobes and backlobe (40-50 dB down), low cross-polarized levels (20-25 dB down), and independent control of E- and H-plane beamwidths over an ultra-wide wide bandwidth, say 2-18 GHz, are some of the strong points of this new antenna type.
