A Multiband Quasi-Yagi Type Antenna

Abstract

Abstract-A new design of multiband quasi-Yagi type antenna for 700 MHz band, GSM900, DCS1800, GPS, and Bluetooth/WLAN applications is presented. In contrast to conventional quasi-Yagi antenna design, our proposed antenna realizes the multiband performance by interaction between the section extended ground and the derived driver element which is a branch of driver dipole element. The parametric studies of the proposed antenna are discussed to explore the antenna operating mechanism. The performances of the antenna are demonstrated along with measured and simulated results.Index Terms-700 MHz band, antenna, multiband antenna, quasi-Yagi antenna.

Analytical, Simulation and Measurement Studies of a Dual-Band Open-Sleeve Curved Meander Line Antenna on a Flexible Substrate

“…The radiating element consists on a meander monopole line. It was chosen in order to reduce the length of the antenna [7,8]. This driven element is formed of two wires sewn in zigzag, a metallic wire of diameter d = 0.30 mm and a classical cotton wire.…”

“…They must be light weight, low profile, highly flexible, have a high impact and a simple structure. This has resulted in new antenna designs [4], like fractal antennas [5,6] for wideband or multiband systems, meander elements [7][8][9], or open-sleeve antennas [10][11][12][13] for multiband frequencies. To reduce the volume of the antennas, flexible substrate [14][15][16][17][18][19][20] are used.…”

A Wideband Slot Antenna with Folded Parasitic Line for Multiple Band Operation

“…Also, many wireless communication systems require antennas responding to multiband operation with low profile. However, multiband antennas could be designed by using either multi-resonators or wideband notch technique to produce multiple band operation [5][6][7][8].…”

A Novel Design of Folded Dipole for Broadband Printed Yagi-Uda Antenna

“…The parasitic directors are used to enhance the radiation in the forward end fire direction. Owing to the advantages of high gain, end-fire radiation pattern, ease-fabrication and low cost, the printed Yagi-Uda antenna has attracted much interest with many applications in radar, millimeterwave imaging, wireless communication system and etc.. As the development of wireless communication proceeding, many significant efforts have been made to design printed Yagi-Uda antenna and improve its performance for several wireless communications such as the series-fed two bowtie dipole array for enhancing the front-to-back ratio [2], the Sierpinki or Koch fractals shaped dipole elements for reduction in size [3][4][5] and dipole driver with derived sections for multiband operation [6,7].…”
