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 side of the feedline with alternating phase, at specific intervals

Antennas are at the foremost and center of any communication system. They play the key role of transmitting and receiving signals between the source and the destinations. There are many types of antennas in different sizes and unique performance characteristics. This article aims to provide a thorough understanding of omnidirectional antennas and yagi antennas and how they compare against each other. Overview of Antennas An antenna is a device used for converting electric power into electromagnetic waves and vice versa. They transmit and receive signals and act as the linking devices in communication systems. The antenna plays a major role in determining the performance of a communication system. Antennas are found with different physical structures, working frequency ranges, gain, directivity, polarity, etc., and are classified into different types based on them. A few of the most common types of antennas are described briefly below. Log periodic antenna: This type of antenna is made of a series of dipoles placed along the

Antennas can be considered as the most essential component of modern-day communication systems allowing electromagnetic waves transmission and reception over long distances or nearby. Antennas are available in different shapes and configurations to suit different applications such as horn antennas, parabolic antennas, yagi antennas, panel antennas, helical antennas, etc. This article aims to provide a thorough understanding of panel antennas and yagi antennas and how they compare against each other. Overview of Antennas In simple terms, an antenna is a device used for receiving or transmitting signals by converting electric power into electromagnetic waves and vice versa, thus enabling communication. Antennas are the linking device between a transmitter and the free space or the free space and a receiver in a communication system. The quality of the communication system, particularly wireless communication will rely heavily on the quality and performance of the antenna. There are certain parameters of an antenna such as the working frequency range, gain, directivity, polarity, etc.
