Reconfigurable yagi uda antenna based on a silicon reflector pdf. The gamma match is often used for providing yagi impedance matching. A log periodic antenna lp also known as a log periodic array or log periodic aerial is a multi element directional antenna designed to operate over a wide band of frequencies. Directors are then added.

In understanding the basic yagi antenna theory the different elements of the yagi antenna react in a complex and interrelated way. As seen in the diagram the outer of the coax feeder is connected to the centre of the driven element of the yagi antenna where the voltage is zero. Below is a yagi antenna design according to some references as follows. Goal is to be able to use both yagi antennas and a tri band vertical on each separate frequency with one main feedline to the antenna installation.

Yc0pe by ridwan lesmana13 2. A yagiuda antenna commonly known as a yagi antenna is a directional antenna consisting of multiple parallel elements in a line usually half wave dipoles made of metal rods. Typically a reflector is the first element added in any yagi design as this gives the most additional gain often around 4 to 5 db. The yagi antenna or yagi uda antenna or aerial is a particularly popular form of antenna where directivity and gain are required.

For mid ranges of the number of directors each director provides very roughly 1 db of gain. The most obvious factor that affects the yagi antenna gain is the number of elements in the antenna. Yagi antennas belong to the longitudinal radiators and use radiation excited elements. As a result of the fact that the voltage is zero the driven element may also be connected.

Although the yagi has become particularly popular for television reception it is also used in many other applications both domestic and commercial or professional. One of the major keys to understanding yagi theory is a knowledge of the phases of the currents flowing in the different elements of the antenna.
