It is the most popular and easy-to-use type of antenna with better performance, which is famous for its high gain and directivity. #knowledge #stream #blog Frequency range The frequency range in which the Yagi-Uda antennas operate is around  30 MHz to 3GHz  which belong to the  VHF  and  UHF  bands. Construction of Yagi-Uda Antenna A Yagi-Uda antenna was seen on top of almost every house during the past decades. The parasitic elements and the dipole together form this Yagi-Uda antenna. The figure shows a  Yagi-Uda antenna . It is seen that there are many directors placed to increase the directivity of the antenna. The feeder is th...

Microstrip is a type of electrical transmission line which can be fabricated using printed circuit board technology, and is used to convey microwave-frequency signals. It consists of a conducting strip separated from a ground plane by a dielectric layer known as the substrate. The most commonly employed microstrip antenna is a rectangular patch which looks like a truncated  microstrip  transmission line. It is approximately of one-half wavelength long. When air is used as the dielectric substrate, the length of the rectangular microstrip antenna is approximately one-half of a free-space  wavelength . As the antenna is loaded with a dielectric as its substrate, the length of the antenna decreases as the relative  dielectric constant  of the substrate increases. The resonant length of the antenna is slightly shorter because of the extended electric "fringing fields" which increase the electrical length of the antenna slightly. An early model of the microst...
