In this paper, a compact log-periodic dipole array (LPDA) antenna is developed at 0.5-10 GHz. This LPDA structure constitutes fewer dipole elements than a conventional LPDA antenna that exhibits ...

Over the years, new antenna models have emerged, such as parabolic, log-periodic, and Yagi-Uda antennas, leading to the development of microstrip antennas [2]. This technological advancement has ...

A conformal log-periodic balloon antenna operating at a very high-frequency (VHF) band is presented in this communication. The antenna consists of eight conformal bowtie-dipole elements cross-fed by a ...

"ABSTRACT A Mathematical analysis of the logarithmically periodic dipole class of frequency independent antennas, which takes into account the mutual coupling between dipole elements, is described.

When you think of directional ham radio antennas, you probably think of a Yagi, cubical quad, or a log-periodic antenna. These antennas usually are in a horizontal configuration up on a high tower.… ...
