A Novel Yagi-Uda Dipole Array Fed by A Microstrip-To-CPS Transition
We report the design and experiment of a novel Yagi-Uda dipole array fed by a MS-to-CPS transition. The Yagi-Uda array having one director on the same plane of the dielectric substrate as the driver element shows higher gain (9.1dB) than microstrip patch antennas and a much wider bandwidth (10.3%). The measured front-to-back ratio is about 15dB. This novel design should become an important alte...
متن کاملWideband Double-dipole Yagi-uda Antenna Fed by a Microstrip-slot Coplanar Stripline Transition
Abstract—This paper describes a wideband double-dipole Yagi-Uda antenna fed by a microstrip-slot coplanar stripline transition. The conventional dipole driver of a Yagi-Uda antenna is replaced by two parallel dipoles with different lengths to achieve multi-resonances, and a small, tapered ground plane is used to allow flexibility in the placement of a pair of reflectors for effective reflection...
متن کاملA Novel Design of Folded Dipole for Broadband Printed Yagi-Uda Antenna
In this paper, a printed wideband Yagi-Uda antenna with a novel folded dipole driver is proposed. The folded dipole driver is comprised of a folded dipole and a microstrip feedline which functions as an internal balun to mainly determine its wide impedance bandwidth. With the optimized parameters, an operating band of 1.69 GHz ∼ 2.72 GHz can be obtained. Besides the folded dipole driver, the br...
متن کاملMicrostrip Yagi-Uda Antenna for 2.45 GHz RFID Handheld Reader
This paper proposes a compact microstrip Yagi-Uda antenna for 2.45 GHz radio frequency identification (RFID) handheld reader applications. The proposed antenna is etched on a piece of FR4 substrate with an overall size of 65 mm × 55 mm ×1.6 mm and consists of a microstrip balun, a dipole, and a director. The ground plane is designed to act as a reflector that contributes to enhancing the antenn...
متن کاملDesign and Fabrication of a High-gain Microstrip-fed Yagi-Uda Antenna
In this report, Yagi-Uda antenna is analyzed and simulated by developing a Matlab program. The analysis of Yagi antenna has been based on considering a single mode cosine current distribution on all elements. The antenna is viewed as a special kind of center-driven dipole array in which all but the actual exciter element are short-circuited at the terminals. Currents are induced in the parasiti...
