In modern communication systems, antennas are essential components that allow radio waves to transmit and receive at various frequencies. Very high frequency (VHF) and ultra-high frequency (UHF) antennas are two popular varieties that meet a range of communication demands. A UHF antenna is a device intended for receiving and transmitting signals in the UHF band, which is commonly between 300 MHz and 3 GHz. UHF is less effective when passed through nearby obstructions since its frequency waves are shorter. These antennas are used in various applications including, An antenna made to receive and transmit signals in the Very High Frequency band is known as a VHF antenna. This frequency range covers 30 to 300 MHz and is used, among other things such as, There are several different types of VHF antennas, including VHF Yagi, dipole, and ground plane antennas. Each type of antenna has unique directivity and bandwidth characteristics, and they are an essential part of the antenna and necessary

UHF antenna is a device that receive and transmit signals in the Ultra High Frequency range which is typically considered to be between 300 MHz and 3 GHz. UHF antennas are used in various applications such as television broadcasting, wireless communication, mobile communication, GPS, etc., and are useful in multiple industries. In this article, we will provide an overview of UHF antennas, covering their design considerations, applications, performance comparisons with other frequency bands, and information on the growing market trends for UHF antennas in various industries. What is UHF? UHF stands for Ultra High Frequency which is generally considered for frequencies between 300 MHz and 3 GHz. It was first discovered in the early 20th century and quickly became a main part of communication systems. Early applications of the UHF band included military radar, radio communications, and television broadcasting. The maximum range of UHF transmission is between 30 and 40 miles (48 to 64 km) or less, depending on local terrain. Radio Repeaters can be used

Antennas are essential elements in a communication system. They are responsible for transmitting and receiving signals wirelessly over a range of operations. Depending on the shape, size, and electromagnetic properties antennas can be categorized into several types of antennas. Among these different types of antennas, Yagi antenna play a crucial role in telecommunications. In this article, we will explore how Yagi antennas work by understanding their design, history, and factors that govern their performance. Finally, we will investigate some of the widely used applications of Yagi antennas in different wireless communication systems. Historical Background Yagi antenna is a directional antenna that was introduced by two Japanese scientists in 1926. The scientists who invented the Yagi-Uda antenna are Shintaro Uda and his supervisor Hidetsugu Yagi. Shintaro was responsible for formulating the theory behind the antenna while Yagi helped him to popularize his ideas with the global community. The oldest application of Yagi-Uda antennas involved radar systems used in World War II.
