Abstract: A Mono-Blade Antenna is disclosed which operates over many octaves of bandwidth. Electromagnetic waveforms may be transmitted and received with multi-decade bandwidth using: a metal ground plane, a Mono-Blade Antenna element fixed above the ground plane, and a coaxial transmission line feed which is connected to the antenna element and the ground plane. The antenna element has three sections: a throat, a mouth, and a radial tip. The throat is comparatively narrow and serves as the element feed point by being connected to the center conductor of the coaxial cable. The mouth is the mid-section of the antenna element, which is the widest section of the blade. The tip of the blade is formed by an arc of approximately constant radius, which results in a low voltage standing wave ratio.

Abstract: Multi-dimensional, non-linked method and apparatus for producing a simulated feeling of force on a preselected location on a human operator in a synthesized environment accomplished by generating a first, constant, stationary electromagnetic field and a second, varying electromagnetic field local to the human operator. The variance of the second electromagnetic field is controlled by electrical currents which are responsive to parameters describing the position and orientation of said preselected location on the human operator and such variance results in attraction and repulsion of the first and second electromagnetic fields emulating a feeling of force on the human subject.
