A novel frequency and pattern reconfigurable Yagi antenna is proposed. The antenna is formed by a driver, a reflector and two directors. The introduction of switches using a PIN diode at the arms of the driver element produces three switchable frequencies at 1.25 GHz, 1.85 GHz and 2.45 GHz. ...
Using a knowledge of this fact, it is possible to create three different types of element that have different effects on the overall radiation pattern of the antenna.There are three types of element within a Yagi antenna:Driven element: The driven element is the Yagi antenna element to which ...

The antenna consists of four elements, including one driven patch, one parasitic patch placed along the E-plane ...
but its presence also distorts the antenna pattern, influences the noise figure, and ultimately degrades the G/T performance. This degradation contrasts sharply with the model's predictions if the feed point box was omitted. The only discernible benefit of the box is aesthetic, making the Yagi...

Radiation PatternThe directional pattern of the Yagi-Uda antenna is highly directive as shown in the figure given below.The minor lobes are suppressed and the directivity of the major lobe is increased by the addition of directors to the antenna.Advantages...
If the electrical length of the parasitic element is shorter than the driven element, the radiation pattern reversed and the parasitic element became a Director (D) always in the two-elements of the Yagi antenna. FAQ's:what does the antenna difference between Yagi-Uda and Yagi? A television ...
