Motivated by the fabrication potential of multi-walled carbon nanotube structures, we numerically investigated a paired structure consisting of two metallic spheres each grown on one end of a multi-walled nanotube. The paired two-segmented structure is cap ...
The effect of substrate permittivity on UWB antenna radiation is studied. Microstrip and CPW-fed UWB monopoles are designed using substrates with different dielectric constants. The radiation patterns are measured. The transfer function of a two identical ...

The JET bolometer camera system allows greatly improved tomographic reconstruction of the radiation pattern on a timescale of the order of the typical duration of a Type I ELM period (approximate to 0.1-0.4 ms). The ELM-induced radiation is always higher a ...
Multilayered media with printed circuits embedded between their dielectric layers are one of the most successful technologies for manufacturing planar structures with a very promising performance-to-price ratio. These planar structures include many differe ...
One of the most promising bands for long-range radiocommunications is the Ka-band (25-40 GHz). This is due to the existence of a natural radio transmission window around 30 GHz. Both terrestrial and satellite transmission systems are planned on this freque ...
This letter presents a Vivaldi antenna having the capability of dynamically rejecting interferers, mainly aiming at multistandard communication with dynamic frequencies allocation. Only half of the Vivaldi is used and placed over a ground plane, which is s ...

Microwave cavities, or microwave resonators, are used in a variety of applications, including filters, oscillators, frequency meters, and tuned amplifiers. The ever-increasing demand for compact and/or portable telecommunication systems drives the need for ...
This work presents a new rigorous investigation of corona effects in microstrip components. To carry out the investigation, a new software tool has been developed. The new tool first calculates the electromagnetic fields in complex microstrip structures us ...
This paper presents an innovative switched-beam architecture for a low-cost mobile-terminal antenna, suitable for linear-polarized satellite communications systems. This antenna concept can produce twelve adjacent sector beams that cover the full azimuth f ...
