A Novel Technique for Realization of Circular Polarization in Planar Inverted F Antenna | #IJSRD


In this paper various techniques for realization of circular polarization in Planar Inverted F Antenna for Nano satellite applications at 2.4Ghz (s-Band) is presented and several research works done on PIFA are categorized and discussed. PIFA is most commonly used and extensively demanded antenna especially in mobile communication because of its low profile, moderate gain, good radiation pattern, multiband operation.

This  Article represents past study on planar inverted f antenna. After study of various research papers it can be concluded that with the suitable technique circular polarization can be generated in this antenna and thus can be useful in nanosatellite applications
             PIFA can be thought of as a combination of the inverted-F (IFA) and the short-circuit rectangular micro strip antennas. Quarter-wavelength Patch Antenna, which leads into the Planar Inverted-F Antenna (PIFA). It is small and has a low profile, making it suitable for mounting on portable equipment. It is a variant of monopole where the top section has been folded down so as to be parallel with ground plane. This is done to reduce the height of the antenna, while maintaining resonant training length
These are the applications of Planar Inverted F Antenna:
  1. Mobile Communication
  2. Satellite communication
  3. Direct broadcast services

#IJSRD | Wireless Phone Charger: the uniqueness and the features


Wowhoo Wireless Phone Charger: the uniqueness and the features
blog

Major wireless phone carriers have all been adapting the Qi wireless technology. Additionally many car manufactures are adding them to their 2014-2015 models. Manufactures include but are not limited to the following: Jeep, Toyota, Prius Harrier, Mercedes Benz, BMW, Volkswagen, Audi aswell as Porsche.

Due to the new and improved design and usability our initial launch date has been revised from Jan 7th to March 1st. we added approximately 8mm to our diameter to allow a better internal design.  The small revision to the Wowhoo charger allow us to get that quicker charge which is most important. The 10% is a big jump in charging speed.

Invention Awards 2014: A Personal Electric Airplane That Won’t Need A Runway | Research lets do it…


More than half of all personal aircraft accidents occur during takeoffs or landings. That’s why inventor and entrepreneur JoeBen Bevirt—known for designing airplane-like wind energy turbines—is intent on making runways obsolete. Bevirt, 40, has mobilized his wind energy team to create a personal electric airplane called S2 that takes off vertically, like a helicopter, and flies aerodynamically, like an airplane.

Research lets Do it. . . #IJSRD

No full-scale prototype exists yet, but Bevirt and his team have built about two dozen 10-pound models to demonstrate their concept works. NASA has taken notice and is now funding the development of a 55-pound unmanned aerial vehicle. Supercomputer simulations of a full-scale, 1,700-pound S2 suggest it could fly two people about 200 miles (New York City to Boston) in an hour on 50 kilowatt-hours of electricity, or roughly equivalent to 1.5 gallons of fuel used by a typical two-seat airplane—which would make the new aircraft about five times more efficient.

FLEXIBILITY

Retractable arms reposition the motors to transition between vertical takeoff, forward flight, and landing.
