A log periodic antenna is a type of multi-element directional antenna that is used in high-power shortwave broadcasting stations. This type of antenna can transmit over several frequencies and has a wide bandwidth.
The design of a log-periodic antenna is similar to that of a three-element Yagi antenna. The driven element is a dipole element located closest to the resonant frequency, while the adjacent elements act as a reflector or director. The shorter element in front acts as a reflector and the longer element in the back acts as a director. All of these elements contribute to gain. The result is a higher overall gain at any given frequency than the Yagi antenna of the same size and shape.
The antenna is designed for directional transmission over a wide frequency range. The wide bandwidth and high directivity of this type of antenna makes it an excellent choice for testing for radiated emissions in electronic devices. You can use it in a variety of applications, including television, cell phones, and computer monitors. If you're looking for an antenna with a wide bandwidth and low noise level, a log periodic antenna may be the answer.
Log periodic antenna‘s flat response makes it an excellent choice for testing radiated emissions and other emf emissions. Its high directivity and wide bandwidth make it a great choice for many applications. They are often used in broadcasting. The wide bandwidth and flat response of a log period are essential for such high-frequency applications.
Log periodic antennas is also ideal for testing EMC, which is an important issue in any electronic product. The log periodic antenna's flat response over a broad range of frequencies makes it an excellent option for testing EMC. This characteristic makes it ideal for mobile applications.
