Abstract:
This paper presents two polarization reconfigurable patch antennas using semiconductor distributed doped areas (ScDDAs) as active components. One proposed antenna has a switching polarization between two linear ones, while the other one has a polarization able to commute from a linear to a circular one. The antennas are designed on a silicon substrate in order to have the ScDDAs integrated in the substrate, overcoming the needs of classical PIN diodes. Therefore, the proposed co-design method between the antenna and the ScDDAs permits us to optimize the global reconfigurable function, designin

Abstract:
The ever-increasing demand for larger bandwidth with seamless and fast data access for commuters resulted in developing new challenges for wireless service providers. With the increasing network mobility, the communication channel based characteristics between base stations and mobile users are changing rapidly. To meet these challenges, smart antennas have become an essential component in the emerging wireless systems. The increasing requirement for increasing stable network performance and reducing electromagnetic pollution has strengthened smart antenna adoption. The primary objective of th

Weather affects many aspects of our daily lives from our individual commutes to the global economy. Although much progress has been made in understanding atmospheric physics and weather forecasting, there is still a need for better in situ atmospheric data. Forecasts are based on high performance computer models which solve the differential equations that represent the dynamics of the atmosphere. In all of these models, initial conditions based on the current state of the atmosphere are ingested into the models.

On 17 January 2013, Wired chose the smart contact lens as one of “7 Massive Ideas That Could Change the World” describing a Google-led research project. Wired explains that the inventor, Dr. Babak Parviz, wants to build a microsystem on a contact lens: “Using radios no wider than a few human hairs, he thinks these lenses can augment reality and incidentally eliminate the need for displays on phones, PCs, and widescreen TVs”. Explained further in other sources, the technology entails an antenna, circuits embedded into a contact lens, GPS, and an LED to project images on the eye, creating a virt

All over the United States, phone companies are planting artificial trees.

Holes in its synthetic brown bark admit bundles of black cables that travel up through the hollow metal trunk to the wireless digital phone antennas hidden among the plastic pine branches high above. In the desert near Phoenix, Arizona, where pines are scarce, another phone company plans to conceal its antennas inside a giant, imitation saguaro cactus. Evidently some large corpor

The aftermath of the attacks also forced the closure of PATH’s key station at Exchange Place that serves Jersey City, New Jersey’s expanding “Gold Coast” business and residential area.
