Rectenna
... A rectenna is a rectifying antenna, a special type of antenna that is used to convert microwave energy into direct current electricity ... The diode rectifies the AC current induced in the antenna by the microwaves, to produce DC power, which powers a load connected across the diode ... Brown, who demonstrated it with a model helicopter powered by microwaves transmitted from the ground, received by an attached rectenna ...

Microwave Transmission - Parabolic (microwave) Antenna
... To direct microwaves in narrow beams for point-to-point communication links or radiolocation (radar), a parabolic antenna is usually used ... antenna that uses a parabolic reflector to direct the microwaves ... The relatively short wavelength of microwaves allows reasonably sized dishes to exhibit the desired highly directional response for both receiving and transmitting ...

Auto Relay - Microwaves
... Microwaves also cause these strange "relays" when they are just plugged in to an outlet for the first time ... No one knows for sure why this occurs but speculation is that small chips inside the microwave transmit high powered sound pitches that a television mistakes for a remote frequency ...

Microwave - History and Research
... a spark gap radio transmitter that produced 450 MHz microwaves, in the UHF region ... a bell using millimeter wavelengths, and conducted research into the propagation of microwaves ... Perhaps the first, documented, formal use of the term microwave occurred in 1931 "When trials with wavelengths as low as 18 cm were made known, there was undisguised surprise that the problem ...
