PPT-CHAPTER 5 MICROWAVE ANTENNA

MICROWAVE ANTENNA Definition A conductor or group of conductors used either for radiating electromagnetic energy into space   or for   collecting   it from space or Is a structure which may be described as a metallic object often a wire or a collection of wires through specific design capable of converting high frequency current into EM wave and transmit it into free space at light velocity with high power kW besides receiving EM wave from free space and convert it into high frequency current at much lower power . 1. Microwave power Typically the diameter of the ground plane should be at least 3.. λ. /4. The parameters of helical antenna are-. D- diameter of a turn on the helix antenna.. C- circumference of a turn on the helix antenna.. “God chose the weak things of the world to shame the strong.”. 1 Cor. 1:27. What is Microwave. Microwave Communications.

There's . nothing inherently evil about conveniences, but living in such a world can lead us to develop unhealthy spiritual attitudes. . Baluns. A . balun. . is a device to match a . balanced . antenna . to unbalanced . transmission line such as coax. Used e.g. to connect a dipole antenna to a 50 ohm coaxial cable, where it would be installed .
