some people joke now is the basic demand of food, water and WiFi.As bedtime habit to play with the mobile I nature is no exception, but because of all the room, I sleep the room furthest distance install the router's house, and also several wall insulation in the middle.Because of this problem has been trapped in a weak signal.If I could be directed to enhance the signal intensity of the room, natural problems are solved, have what good way?
if your router can remove the antenna, nature can change better directional antenna, but because a lot of cheap routers can't split open a antenna, a lot of people settle for second best choice for existing fudge antenna, including a cans make parabolic reflecting the way.Although this way can make the antenna has a certain directivity, but want to achieve the best effect is necessary to adjust cans, make antenna is located in the focus of the parabolic position.Is there any easier, better adjustment of the way?
consider another kind of the principle of radar antenna, we can use the principle of yagi antenna to make another kind of creature.Yagi antenna reflector and director, hold most of the signal energy to antenna in front.Using router original rubber antenna as active oscillator, will be part of the energy directional launch out!
by antenna simulation analysis software, we can construct a resonance in the 2.4 GHz yagi antenna.First simulation model of a normal work of whip antenna, in order to imitate the router's own rubber antenna, and then add the reflector and the director, make its form yagi antenna structure, and to adjust.After the adjustment, from the 2.412 GHz to 2.462 GHz range, its working state are in acceptable condition.
for its directivity, we can see through this lobe pattern, you can see in this structure, the most of the energy will be directed toward the front, then the department of energy has been weakened.
you can use all the non-conducting objects to do the fixed frame, such as the use of yogurt box cut out of one, several holes for copper wire, and antenna.Reflector and lead with thick copper wire, 5.7 cm long and 5.08 cm respectively, with forceps truncation.And install the antenna is 3.96 cm and 3.96 cm on both sides of the original antenna distance position, as shown in figure.
when used, the shorter interval to implement the direction of the end point to want to improve the effect of cover, and normal use.Generally like to be able to play the role of promotion of the effects of signal, might as well try.
