Typically, patch antennas are narrowband and their Q factor is inversely proportional to frequency.
The Microstrip patch antennas are well known for their performance and their robust design, fabrication and their extent usage. As it is formed using a microstrip technique by fabricating on a printed circuit board thus is also known as Microstrip antenna or printed antenna. Microstrip antenna are one of the most popular types of printed antenna. New Types of Microstrip Antennas for the Applications. In this article, a single-feed, miniaturized, circularly polarized (CP) microstrip patch antenna (MPA) using Koch fractal geometry for RFID applicatio… New Types of Microstrip Antennas for the Applications Typically, patch antennas are narrowband and their Q factor is inversely proportional to frequency.
Microstrip Antenna. The main reason for the high Q factor is that patch antennas are essentially circuits printed on a relatively thin substrate: the higher the dielectric, the higher the Q factor.
Due to its low profile, conformability to planar and non planar surfaces, ease of integration and light weight, microstrip patch antenna has been foremost choice for various applications. Microwave components such as antennas, couplers, filters, power dividers etc. Microstrip antenna are one of the most popular types of printed antenna. It was invented to allow convenient integration of an antenna and other driving circuitry of a communication system on a common printed-circuit board or a semiconductor chip (Carver and Mink, 1981; Pozar, 1992). Printed microstrip slot antennas have seen wide use in commercial and military wireless applications. Also the study of mutual interaction between electromagnetic radiation of microstrip antennas and adjacent human …
Generally, patch antennas are considered as low profile antennas and are used for microwave frequency applications having frequency greater than 100 MHz . The most widely used printed-circuit antenna is the microstrip patch, which in its simplest form is a rectangular or circular patch of metal fed by the microstrip upper conductor; ... A clever design of the switch biasing network is of great importance in antenna applications. Construction & Working of Micro strip Antennas Micro strip antenna consists of a very thin metallic strip placed on a ground plane with a di-electric material in-between. band has been a choice for several applications like WiMAX standard devices, wireless network equipments [2], weather radar, surface ship radars and satellite communication [3]etc.
