2.4GHz High Gain Directional Antenna Production ----- 2.4GHz Wi-Fi Antenna

We all know that the connection distance between RF wireless network equipment has increased much after high gain antenna, but the price of high gain antennas is indeed expensive, and high-end antennas are more expensive than network equipment. It is not difficult to make your own microwave antenna, because the microwave antenna frequency is high, the wavelength is short, the antenna is small, and the brings are easy to make, easy to make. It is also difficult to make a microwave antenna. Usually, when the VHF band antenna is made, as long as it is done according to the design, it can generally achieve good results, and the size requirements are not so stringent. The microwave antenna is different, and the relatively small size error can make the antenna made unavailable. The antenna to be introduced is an example. The size of the short route is only 4 mm, and the lower limit of the antenna is raised to 2.6GHz, and the gain of 2.55GHz is 9 decibels, at 2.4 The gain of -2.485GHz can be imagined. In this frequency, it is a relatively reasonable choice to adopt a mesh parabolic reflection antenna. It is also close to this frequency band. There are a large number of reflection networks on the market. Take a few yuan, it is very value, yourself As long as you do a 2.4-2.485GHz frequency bandwater source. This design is based on the structure of our products, the structure is easy to self-made, as shown in the following figure. The feed in the figure is docked with a single-sided copper plate. I am afraid that there is no shortage in my hands, and the detailed structure is decomposed as shown below. The material in the figure has a total of only two, 1.5 mm thick copper plates and less than 10 cm long and 50-5 physical radio frequency coaxial foaming cables. One of the large reflectors, two small in the middle, half-wave vibrators, the following squares, and two blocks are also short-circuits. Two vertical bars are very critical, and their length is directly related to the operating frequency range of the antenna, and a few millimeters of errors can cause the antenna to be used normally.
