An antenna is defined by Oxford Dictionary as ? a usually metallic device for radiating or receiving radio waves ?. The IEEE Standard Definitions of terms for Antennas ( IEEE Std 145-1973) defines the antenna or aerial as ? a means for radiating or receiving radio waves ?. In other words the antenna is the transitional structure between free-space and a guiding device. The guiding device or transmission line may take the form of a coaxial line or a hollow pipe (wave guide) and it is used to transport electromagnetic energy from the transmitting ....etc

INTRODUCTION
Let's face it, energy is expensive gas, electricity, whatever. So why pay to cook your food? The challenge we gave was to cook food, without spending any money at all. No electricity, no gas, nothing. And, there are no negative side effects on the environment, resulting from our hot dog. What we came up with was...the parabola. So by using the properties of parabolas, we're going to cook a hot dog. Essentially, we're using math to cook hot dog ....etc

The device was developed by Ramirez and Roger Green in the university of Warwick?s engineering department. It brings benefits to wireless networks, electronic households and data transfer. It applies techniques used to manipulate radio frequency to select the incoming ?signal frequency ? carried on the infrared beam to produce the optical equivalent of the radio. Optical antenna serves the same purpose as in electronic one .It must collect energy from an area and channel it t o the receiving element. Optical antenna uses a combination of precis ....etc
