LPDA Antenna and Advantages

LPDA Antenna

The first thing you will notice about regular antennas is how they are made; they’re usually made of metal sheets or steel rods. On the other hand, there are some specific types of antennas called log periodic antennas (LPA) that have an organic element inside them to provide the desired characteristics when it comes to their performance. The LPA’s main goals consist of their ability to offer directivity, gain, and impedance of interest for communications applications. In general, there are two types of such antennas that are used to provide both of these capabilities. They are also known as long-range and narrowband antennas respectively. For a better understanding of what is a log periodic antenna, we also have written about this type of antenna. All in all, we believe that most readers will realize the existence of LPA and how it works.

When someone hears about a new product or service like LPA, chances are he’s thinking about a brand-new model or type of antenna. He might be considering adding it into his everyday life, especially if he runs a heavy commercial area around his house or business. There are lots of models available today. The most popular ones include the high voltage attenuated linear feed back and even beamforming antennas, which can also be customized. Here is a list of different products from each category. We also have discussed the pros and cons of each model. You can find the complete details of each one here.

How Log Periodic Antennas Works?

Log periodic antennas are made up of layers of air such as air or crystals such as crystal. These layers of air function as layers of electrons. This concept is more closely related to magnetism than electronic devices. When applied to radiated waves, these types of antennas can be found everywhere – on radio equipment, satellite dishes, cell phones, TV, and so forth. Most often, however, they’re also used for the transmission of power, communication and data services. The idea behind using them was that they were very sensitive to certain frequencies. But over time, they have become less sensitive, and thus, less important. With that, companies and individuals start shifting to other technologies. Their primary focus is on building larger antenna systems, which offers increased quality.

Types Of Log Periodic Antennas That Are Used Today

There are two types of log periodic antennas: Type A’s which are built on structures called “metal stacks” and Type B’s which are built on structures called “metal plates,” just like the name suggests. While the main difference between them lies in their material that has been used to build them, there is not much else to draw attention. However, Type A and Type B antenna designations are still used. Each type of antenna provides particular properties that allow its users to take advantage of them.

What you need to know about switching and routing

The main advantage of using a periodical antenna is that its primary purpose is to generate radio waves on the desired frequency range. A log periodic antenna can be said to exhibit the characteristics as shown in below equation :

where y is the desired frequency, f is the operating frequency, and θ is the channel dimension.

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 :
