Radiation Q of small vertically polarized dipole antennas over a ground planeAlthough the radiation quality factor of small antennas in free space has been investigated extensively in the past, the exact effect of a conducting ground plane on the antenna bandwidth is still not clearly understood. ...
A theory is presented giving far-field radiation patterns and surface-wave behavior for vertically polarized antennas located at zero height over flat ground, with a surface impedance which can be discontinuous along a radius from the antenna. The theory is based on the radiation from the surface...
An antenna for providing a vertically polarized omnidirectional horizontal radiation pattern comprising colinear dipoles. Suitable feeding arrangements are provided for electromagnetically feeding the dipoles with a signal. An axially extending conductive member is spaced on either side of the colinear dipoles...
This paper proposes a quasi-endfire vertical polarized antenna array at 28.8 GHz for 5G mobile applications. The array element is composed of a dipole antenna with its two ends shorted by metallic via walls. The via walls have the same omni-directional radiation and 180° phase shift which ge...
A vertically polarized broadband antenna including a log-periodiclike array of elements, providing the high gain at the higher frequencies, characteristic of a conventional dipole-type vertically polarized log-periodic antenna, and reduced antenna height characteristic of a conventional monopole-type ...
A vertically polarized log-period antenna of the dipole type is disclosed, in which the top ends of all the dipole elements are directly coupled to the antenna's main support catenary. The antenna's feed line is used to perform a structural support function, so as to reduce the structural ...
