Numerous pattern-reconfigurable antennas stemmed from the variations of the Yagi-Uda antenna
was developed in 1920 and it is known to be the most conventional travelling wave antenna.
In Section 2, we introduce the traditional Yagi-Uda antenna
first and then propose the bidirectional Yagi antenna.
This principle of antenna operation is much like a Yagi-Uda antenna
set on a dielectric substrate backed by a finite ground plane.
Follow the conventional Yagi-Uda antenna
, three different rings are named as director, driven element and reflector respectively in this paper.

A standard Yagi-Uda antenna
is made up of a set of parallel metal rods that gradually decrease in length.
Several antenna types such as microstrip antenna, dipole, monopole, and Yagi-Uda antenna
are used as the receiving antenna for RF energy harvesting.

Common narrow band antenna designs are dish antennas, dipole, loop, microstrip patch or Yagi-Uda antenna
A classic example is the Yagi-Uda antenna
with an active feed element, a passive reflector and several passive directors.
