A new dual-band circularly polarized microstrip antenna is presented experimentally. In this paper, using dual-radiator a new design dual-band antenna can be obtained. The frequency ratio of this design is flexible which more than 1.4.
This paper proposes an omni-directional UWB antenna pattern in azimuth cut, low voltage standing wave ratio (VSWR), and easy to construct antenna for ultra wideband (UWB) systems. The designed antenna uses the multi circular blade configuration with a radiating element and on two different ground planes (square and circular ground shape). The multi-circular… (More)
This paper presents a practical and simple broadside coupled-line balun with multi-layers profile microstrip line and broadside coupling structure to enhance the coupled coefficient and balanced output bandwidth. Designed broadside coupled-line balun design with a symmetric quarter wavelength coupled-line is developed to increase wider bandwidth efficiency… (More)
—Design of a novel circularly polarized (CP) rectenna (rectifying antenna) at 925MHz for wireless power transmission (WPT) applications involving wireless power transfer to low power consumption wireless device is proposed. In order to build the rectenna, a CP wide-slot antenna and a finite ground coplanar waveguide (CPW) circuit both with good impedance… (More)
A dual-band dielectric resonator antenna with inverse T-shape parasitic strip is investigated experimentally. Using an additional inverse T-shape parasitic strip mounted on the dielectric resonator can be induced a higher mode whose radiation patterns have broadside characteristics. Both the radiation patterns of low and high resonant frequencies have no… (More)
The design relates generally to the field on antennas and more specifically, to a low profile linear polarized H-shape dipole antenna. The antenna includes a printed circuit board that has a dielectric substrate provided with H-shape face and one dipole element formed on the dielectric substrate. The printed circuit board is also provided with a balance to… (More)
The semi-rigid cable for microwave band as a feeding network structure that effectively excited tapered TEM horn antenna geometry is proposed. The semi-rigid cable to parallel waveguide transition then to fed tapered TEM horn antenna. The designed tapered TEM horn antenna has the merits such as wideband, simple feeding network, low profile compact size with… (More)
