Problems solved by technology

However, it is difficult to maintain high-quality wireless communication for wireless communication terminals that deviate from the line-of-sight of the AP antenna using conventional antenna systems, such as when there is a wall between the terminal and the AP antenna
According to the worst case, the wireless communication with the wireless terminal cannot be carried out using the traditional antenna system
Especially, when the AP antenna is installed close to the wall, the frequency band of the AP antenna may drift

[0031] Such as figure 2 As shown, the built-in antenna system for indoor wireless communication according to the first embodiment of the present invention includes a first access point (AP) antenna 44 and a second AP antenna 46, and the antennas are respectively installed on a In both surfaces of a certain wall 10 in the building; and the first AP 40 , that is, a radio frequency unit is connected to the first and second antennas 44 and 46 . The first AP 40 is mounted on the exterior of the wall 10 and separated from the first and second AP antennas 44 and 46 . There is also a first power splitter 42 connected to the first AP 40 and the first and second AP antennas 44 and 46 placed in the wall 10 between the first AP 40 and the first and second AP antennas 44 and 46 . The first power divider 42 divides a signal transmitted from the first AP 40 into two equal parts, and supplies the divided signal to the first and second AP antennas 44 and 46 . The first AP 40 and the first p...

[0041] The built-in antenna system according to the second embodiment of the present invention is characterized in that the antenna system is installed through a wall.

[0042] In particular, refer to the attached image 3 , there is a hole h in wall 10. An antenna device including a first horn antenna 62a, a second horn antenna 62b, a feeder 63 and a sliding waveguide wall 64 is installed in the hole h to transmit signals to wireless communication terminals (not shown) installed on both sides of the wall 10, The transmitted signal is sent from a second AP 60 outside the wall 10 . A second AP 60 outside the wall 10 is connected to an antenna arrangement in the wall 10 using a second RF cable 66 . The first and second horn antennas 62a and 62b are installed at the two ends of the hole h, and parallel to the wall 10, and transmit the signal output from the feeder 63 to the wireless communication terminals (not shown in the figure) that are on both sides of the wall 10 output)...

Abstract

A built-in antenna system for indoor wireless communications includes an AP antenna, all of the surfaces of which, except for an emitting surface, are installed behind wall surfaces in a wall of a building, and includes an access point (AP) (or an RF unit) connected to the AP antenna. Alternatively, the antenna system includes an antenna structure that is installed to pass through a selected wall of a building and an AP (or RF unit) connected to the antenna structure, the antenna structure having a sliding structure that can be adjusted according to the thickness of the wall. The shift of a frequency band caused by the wall may be avoided, and high-quality wireless communications is achieved regardless of the location of a wireless communication terminal in the building. Further, it is possible to increase the intensity of an electric field at the position of the terminal.

Description

technical field [0001] The present invention relates to a wireless communication antenna system, in particular to a built-in antenna system for indoor wireless communication. Background technique [0002] The use of wireless communication devices has high mobility. Wireless communication devices such as network dialers have been widely used in home networks due to their superior performance. Therefore, more energy is spent on how to improve the performance of the built-in antenna to improve the quality of wireless communication. [0003] Usually, indoor wireless communication is mainly performed between an access point (AP) of a wireless local area network and a notebook computer, and the said access point has low mobility or no mobility. Therefore, indoor wireless communication has not attracted more attention. [0004] Indoor wireless communication is closely related to the indoor wireless environment. Therefore, before selecting various coefficients to improve the qual...
