These conditions had to be set at the beginning of the simulation process of Yagi antenna. Components have been set into the FEKO environment and the system had been enlarged step by step [5].
In Yagi antenna the radiation characterstics of diapole part is attached with the diapole antenna.
As shown in Figure 3(a), the bidirectional antenna has a frequency offset around 30 MHz (3.3%) from the original Yagi antenna. This small offset can be easily adjusted by optimizing the length of the driven element and spacing between driven element and the directors.

The Yagi antenna, named after the late Hidetsugu Yagi who invented it in 1926 together with his colleagues, is now used as a television antenna.
The null antenna array consisted of two, four-element, directional yagi antennas (Advanced Telemetry Systems, Inc., Isanti, Minnesota), separated by a cross boom 183 centimeters wide, and fastened with T-clamps.
(Nasdaq: PCTI), a leader in Performance Critical TELecom solutions, has launched a new MIMO Yagi antenna supporting licensed Upper 700 MHz A Block spectrum, the company said.

Filtering antennas have been implemented in different forms including rectangular patch [1], circular patch [2], patch array [3], T-shaped antenna [4], slot dipole [5], monopole antenna [6], inverted-L antenna [7], Yagi antenna [8], waveguide slot antenna [9], and dielectric resonator antennas [10].
Since the driver is folded, the spacing between the driver and directors is reduced in comparison with a conventional Yagi antenna. The optimized spacing between the driver and the center of the twisted directors is found to be 20.0 mm (0.08 [lambda]) by the GA, as denoted in Figure 2.
A frequency and pattern reconfigurable Yagi antenna consisting of a PIN diode at the arms of the driver element with three switchable frequencies at 1.25GHz, 1.85GHz and 2.45GHz is discussed in [15].
Figure 10 illustrates the models of Yagi antenna and patch antenna mounted on this plane.
