LPDA Antenna vs. Yagi Antenna
An antenna plays a major role in communication systems as the main component that is responsible for transmitting and receiving signals between the source and the destination. Antennas basically convert electric power into electromagnetic waves and vice versa. There are many types of antennas in different sizes, shapes and performance parameters. The overall performance of a communication system will be heavily dependent on the performance of the antenna and hence it is crucial to select a suitable antenna for the system. This article provides an overview on two of the most common types of antennas, LPDA antennas and Yagi antennas. What is a LPDA antenna? LPDA stands for Logic Periodic Dipole Antenna and is called as such due to the fact that the impedance of this antenna is a logarithmically periodic function of frequency. LPDA antennas are composed of dipole elements that are mounted closely together, parallel, and on either
