ABSTRACT:
A Bi-Blade Antenna is disclosed which will radiate and receive multi-octave electromagnetic waveforms with century bandwidth (i.e. 100 to 1) using two blade antenna elements and a coaxial transmission line feed. The blade antenna elements each have a comparatively narrow throat, a mid-section called a mouth, and a tip. The two throats are fixed in proximity to each other and are fed by the coaxial line feed. The central conductor of the feed is connected to one throat while the outer coaxial conductor is connected to the second throat. The mouth is formed by an arc of constant radius to result in a low voltage standing wave ratio of about 1.19 to 1.
