1. Log-Periodic Antennas

A log-periodic antenna is also called as a log regular array. It really is a multi-element, directional slim beam antenna that works on a variety of frequencies. This antenna is constructed of some dipoles positioned over the antenna axis at different space intervals of your time accompanied by a logarithmic function of consistency. Log-periodic antenna is employed in a variety of applications where adjustable bandwidth is necessary along with antenna gain and Directive .

Bow-Tie Antennas

A bow-tie antenna is also called Biconical antenna or Butterfly antenna. Biconical antenna can be an omnidirectional wide-band antenna. Based on the size of the antenna, it includes low- consistency response, and operates as a high-pass filtration. As the consistency would go to higher limits, from the design rate of recurrence, the radiation style of the antenna gets distorted and spreads.

A lot of the bow-tie antennas are derivatives of biconical antennas. The discone is really as a kind of half-biconical antenna. The bow-tie antenna is planar, and for that reason, directional antenna.
