What is LPDA Antenna and Its Types?

LPD antennas or LPDA antennas are a specific type of directional antenna. LPDA stands for “Log-Periodic Dipole Array” and the antenna is so named because it is made up of a series of dipoles. Since they need a lot of bandwidth to cover the vast television channels in the UHF band (approximately 54–88 and 174–216 MHz), The following page will provide a quick summary of the many antenna types that may be utilized in each frequency band, generally known as the radio frequency band. The majority of them are mentioned below these two categories. The first part will explain all types of antennas.

Types of LPDA Antenna :
Narrowband antennas are antennas that have a wide range of frequencies. Such as those from 5 GHz to 6 GHz. They do not need many diodes because the number of diodes is very few. They work well for outdoor applications, which require good signal strength in environments with strong magnetic fields.

Long Range Antenna: Long-range antennas are antenna systems made of materials that have large densities and large dimensions. Those antennas use a single dipole to transmit or receive energy and are therefore not very sensitive to certain frequency bands. As such, they must be extremely powerful and can transmit and received signals from many places at once. As an example, it’s possible to think of the long-range antennas used in satellite dishes.

As such, they must be extremely powerful and can transmit and received signals from many places at once. Types Of Log Periodic Antennas With High Gain Log periodic antenna are often associated with higher levels of gain in their transmissions. They can be made from materials such as metal sheets, plastic, silicone etc. The biggest factor that determines whether a log periodic antenna has high gain is the density of elements used to make it. If the material used to make the antenna has a very high density, then it will probably be able to produce relatively high gains for both short and long distances. If the antenna does not use a dense material, then the antenna might not have enough of a physical structure (dimensions), and thus, it won’t be able to deliver high gains over a large range of frequencies. If the antenna does use a dense material, it’s important that it uses the right type of material for its construction.

These are some of the major differences between the two types of antenna, but there are more to know.

Log Periodic Antennas are made up of an array with N sections for the primary channel. Each section comprises of an antenna that supports low loss with respect to the original low bandwidth which is chosen by the designer. This results into the generation of n-1 channels at each of two frequencies, so that the overall output will always be 1 (n). A few of these antennas have been defined below.
