  how to convert DC to RF is my first problem and also what kind of antenna is more appropriate to use for transmitting and receiving the power?
  also if u can guide me to good book written on wireless power transmission and also how to design RF antenna.
  am desperately needing your help.
  tks 4 ur first response.

  You can actually use a wireless remote transmitter and receiver module, which takes electricity and data as input...
  You don't need to start from the scratch as they are already built and available. So, now your work will be using the modules and your logic...

  i have the idea using RF antenna to transmit and also receive the electrical power. but my most faced problem is HOW TO CONVERT DC POWER TO RF SIGNAL in order to make it suitable for transmission using RF antenna. i hope my confusion is clear now!!!!!!!!!
  sorry for the previous non understanding

  Now say what is your plan... 😀

  my plan is to amplify the power from supply, convert it to DC and then to RF. then send it through RF antenna to the surrounding which intern is harvested using rectenna (receiving antenna and rectifier, where the rectifier is used to convert the RF signal to DC power).
  finally i hoped to use the power to what ever load i wanted considerably (AC or DC).
  Now can u give me some ideas on the questions i asked before.

  I guess you are trying to do, which repeaters do. But they do for data and are wired and you wanna do it for power but yours is wireless. Is this your idea?

  as i have read the project is not it's first time to be held so am not the inventer but wanted to do it in very accessible materials.
  but why do u ask many questions than answering my help request

  hi hiwot,
  i hope it helps.
  this is how we transmit tx power between two nodes in cellular communication.

  I don't whether u or me is lucky one.. i too decided to do project on this.
  u can transmit power not using RF, but, using microwave.. microwave has shortest length n travel long distance..
  Problem i faced during course is
  1. cost of microwave is massive.
  2. design of antenna is complicated.
  find answer for these to, u can surely do it.. not too long. But, for a distance of less than 5m...
  ALL THE BEST.
