How to DIY wi-fi booster/signal amplifier?

Is there any possible way to increase wi-fi signal or can make it not fluctuating while it connected? I mean boost it for the better connection? In example, in my room, my laptop only can receive 1 bar only, so I want to boost it to full bar. If someone there got the drawing for the printed board, please do attach it here so I can print it on my board later. I believe the DIY version is more cheaper than buy one at the store. Do include the full name of the components. Your helps will be very much appreciated! thanks!
