How to make 2.4GHz high-gain directional antenna
|
We all know that RF wireless network equipment to connect to spend away from high-gain antennas can increase a lot, but the price of high-gain antenna also really expensive, high-end network equipment is more expensive than the antenna or even much more expensive.

Want to make yourself a microwave antenna is not difficult, because the high frequency microwave antenna, wave length, the antenna is small, and thus bring the material is easy to get, making easy. Do it yourself microwave antenna is also difficult on the one hand. Usually make the VHF band antenna, as long as the size in accordance with well designed, can often get good results, the size requirements are less stringent. Microwave antenna is different, relatively small size of the error can be made so that the antenna is not available. The following will be presented to the antenna, for example, only a quarter the size of a small short line of 4 mm, the antenna will be increased to a minimum frequency of 2.6GHz, 2.55GHz gain in the low 9 dB at 2.4 -2.485GHz gain can imagine. The band, with mesh parabolic reflector antenna should be a more reasonable choice, just our MMDS is also near the band, there are a lot of reflection on the market supply network, a few dollars one side, where great value with their own just do a 2.4-2.485GHz frequency band feed on it. please Click hereto get our dipole antenna
The design of the structure with reference to expand our product down, the structure of the standard for easy self-derived, see below. Figure in a total of only two materials, 1.5 mm thick laminates and less than 10 cm long period of 50-5 physical foaming coaxial RF cable. Above for a large reflector in the middle to make two small half-wave dipole, following a square as a support, but also for the upper and lower two short points. Two bars is crucial, direct relationship between the length of the antenna operating frequency range, a few millimeters of error can result, the antenna is not working. please Click hereto get our dipole antenna
