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)
—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 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)
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)
The Health Authority - Abu Dhabi (HAAD) mobile e-Service is a smartphone or smart device installed with the HAAD mobile app. This connects to one or more e-services at the HAAD Cloud to facilitate healthcare services for the residents at the Emirate of Abu Dhabi in the United Arab Emirates (UAE). A mobile device in this context can be effectively considered(More)
The circuit of the designed CCP is shown in Fig. 10. The power transmission efficiency of the CCP shown in Fig. 11 demonstrates it's a function of coil gap and displacement. The experimental results show that the output voltage of the CCP is 5V at the induction coil gap of 2mm without any displacement. The maximum transmission efficiency is about 41%, and(More)
