چکیده

This paper introduces a novel variation of the vee dipole antenna consisting of two coplanar vee dipoles with a common feed point. It is referred to as a double-vee dipole. Radiation characteristics of the double-vee dipole antenna are investigated numerically and experimentally. It is shown that the double-vee dipole can provide significantly higher directivity and lower sidelobes and back radiation than the conventional vee dipole. With increasing arm length, the directivity of the double-vee dipole exhibits a series of local maxima. Measured and predicted radiation patterns for a fabricated double-vee dipole are presented and shown to be in good agreement.

Measured Performance of Low-Sidelobe Narrow-Wall Slotted Waveguide Planar Antenna in Millimeter-Wave Band

Low sidelobe slotted waveguide antenna is developed in the millimeter-wave band. Millimeter-wave technologies are expected to apply to automotive radars and high-bit-rate mobile communication systems because high gain and narrow beam-width is possible even though the physical size of the antenna aperture is small. Waveguide antenna is advantageous for high gain applications since the feeding lo...

Robust beamformer weight design for broadband matched-field processsing

Matchedeld beamforming has been proposed for localizing wideband acoustic sources in uncertain underwater channels. While adaptive matchedeld beamforming provides adequate sidelobe suppression for stronger sources, at low signal-to-noise ratios it converges to its quiescent response, in this case the Bartlett beamformer, which has unacceptably high sidelobe levels. In this paper, a design metho...

Gamma-irradiated Venezuelan equine encephalitis vaccines.

The efficacy of Formalin-inactivated Venezuelan equine encephalitis (VEE) vaccine has been reported to be low for man. Although a live VEE vaccine has been shown to be highly effective for the protection of laboratory workers, local and systemic reactions have occurred in approximately 20% of inoculated individuals. Therefore, studies were initiated in an attempt to produce an inactivated vacci...

Time-Domain N-continuous GFDM

Generalized frequency division multiplexing (GFDM) has been a candidate multicarrier scheme in the 5th generation cellular networks for its flexibility of transmitter filter in time and frequency. However, for the circularly shaped transmitter filter, GFDM provides limited performance gain of sidelobe suppression. In this paper, we propose a scheme, called time-domain N-continuous GFDM (TD-NC-G...
