This microstrip dual-band bandpass filter consists of double open-ended resonators and dumbbells designed by using the concept of symmetry. Two transmissions zero appear by zero-degree feed position. The proposed bandpass filter is created to support WLAN applications at 2.45 GHz and 5.20 GHz, respectively. Both insertion losses are greater than −0.9 dB and the return losses are below −18 dB. The...
This paper presents the development of dual-band patch antenna incorporated with split ring resonator (SRR) for Global Positioning System (GPS) and Wireless Local Area Network (WLAN) application. The antenna is composed of 3 layers of copper conductor flanking 2 layers of FR4 Epoxy dielectric substrate with the total thickness of 1.6mm and the dimension of 78.6mm × 48.4mm. The characterization shows...
A novel angular independent dual-band FSS for multi-frequency communication is discussed in this letter. The proposed FSS with closely spaced response is consist of improved cross-shaped metal strips and a dielectric substrate. The unit cell size of the proposed FSS is 0.13λ×0.13λ where λ corresponds to the wavelength of the first resonant frequency. The proposed FSS exhibits dual stop band characteristics...
This paper presents a dual-band design of reflectarray antenna by using metallic elements for high energy efficiency at 28 and 60GHz bands. The dual-band operation is created by considering the frequency bands below and above the cutoff frequency of metallic waveguides. This frequency band separation differentiates the waveguide's characteristics as a resonant and non-resonant reflecting elements,...
A subwavelength superstrate antenna operated at dual-band is proposed using a metasurface (MTS). To design the proposed antenna, the MTS as a partially reflective surface (PRS) has a zero-degree reflection phase at dual-band and is composed of a substrate, periodic metallic square patches and rings on one side, and periodic metallic meshes on the other side. To satisfy the resonance condition of Fabry-Perot...
In this paper, a dual-band dipole with pattern configuration, FPC structure antenna is proposed. By controlling the pin diodes on the reflectors, three modes of radiation pattern are generated for 2G and 5G, respectively, and Reconfiguration antenna can be achieved. DC trace and RF trace are highly integrated and easy to combine with electronic products. Results of measurement for return loss, radiation...
Meta-surface inspired antenna (called MACKEY) which works not only in free space but also on metal plates, was proposed. In this paper, a dual-band MACKEY device, in which the position of the dipole antenna is changed from the center of the substrate, is proposed. Additionally, the conditions for controlling the resonance frequencies are clarified.
