High Performance Two-arm Antenna for Super Wideband Operation

Abstract

A super wideband antenna is proposed to operate in the frequency band 2.2-22 GHz. The antenna has two planar arms printed on the opposite faces of a three-layer dielectric substrate. Each arm of the antenna is capacitively coupled to a circular ring near its end to increase the impedance matching bandwidth. The dielectric substrate is customized to fit the shape of the antenna arms and the parasitic elements to reduce the dielectric loss. The substrate material is composed of three layers. The upper and lower layers are Rogers RO3003 TM of 0.13 mm thickness, and the middle layer is made of paper of 2.3 dielectric constant and 2.7 mm thickness. The antenna is fed through a wide band impedance matching balun of a novel simple design. A prototype of the proposed antenna is fabricated to validate the simulation results. The experimental measurements are in good agreement with the simulation results, and both of them show that the antenna operates efficiently over the frequency band 2.2-22 GHz with minimum radiation efficiency of 97% and maximum gain of 5.2 dBi. The antenna has a bandwidth to dimension ratio (BDR) of 1755.

On the Development of Compact Super-Wideband Fractal Antenna

“…A large number of microstrip patch antenna with SWB characteristics were investigated by researcher in recent past (10)(11)(12)(13)(14)(15)(16)(17)(18)(19)(20)(21)(22)(23)(24)(25)(26)(27)(28) A concentric structured monopole compact patch antenna is proposed in (10) , for SWB application. Electrical dimension of this antenna is 0.18 × 0.16λ 2 and it operates from 1.22 to 47.5 GHz.…”

“…RT/Duroid 5880 of size 0.256 × 0.266 λ 2 is used as substrate for the proposed antenna and it operates from 2.96-100 GHz with a BDR of 2768. In (23) , an antenna with three layer substrate is proposed with SWB features that operates in 2.2-22 GHz frequency range, with 97 % minimum efficiency of radiation and 5.2 dBi maximum gain. It has a BDR of 1755.…”

Flexible Irregular-hexagonal CPW-fed Monopole Antenna with Windmill-shaped Fractals for Ultra-wideband Technology

“…UWB applications enjoy a wide array of antenna options [1,2]. Among these choices are various planar antennas with diverse feeding structures like coaxial, coplanar waveguide type, and microstrip, as well as different shapes [3]. These antennas have proven to be highly suitable for meeting the demands of UWB systems.…”

Super-wideband Fractal Antenna for Future Generations of Wireless Communication

“…WB technology has more advantages than UWB as it provides a larger frequency range. Because of their limitations of low power and relatively slow response to adaptation and signal acquisition, UWB antennas may not be able to operate with high performance for long range wireless communications [1][2][3][4][5][6][7][8][9]. The wider frequency band of SWB antennas in comparison to UWB antennas enables their operation for wider categories of wireless applications including both short-range and long-range communication.…”

“…The wider frequency band of SWB antennas in comparison to UWB antennas enables their operation for wider categories of wireless applications including both short-range and long-range communication. A single SWB antenna can operate simultaneously for multiple operational frequency bands that are required for future mobile communication [1][2][3][4][5][6][7][8][9]. Moreover, compared to UWB, SWB technology offers a larger channel capacity in communication, superior resolution in screening, and higher precision with greater time-accuracy in ranging [1][2][3][4][5][6][7][8][9].…”
