Embodiment Construction

[0052] The gain-adjustable antenna of the present invention is composed of one or more antenna elements, connected in a manner that can be disassembled and assembled each other, and by selecting the number of antenna elements to be assembled, the antenna's Gain, therefore, by increasing or decreasing the number of antenna elements, the gain of the whole antenna can be adjusted.

[0053] refer to figure 1 , the gain-adjustable antenna 10 of the present invention may include a plurality of antenna elements 11, 12, 13 coupled to an external circuit 20 (such as a signal source); in the following description, only two antenna elements Body for illustration, wherein symbol 11 represents the first antenna element, and symbol 12 represents the second antenna element.

[0054] Such as figure 2 and image 3 As shown, the first antenna unit 11 includes a first substrate 31, such as a printed circuit board; a first radiation unit 11b is arranged on the front (first surface) of the fir...

Abstract

This invention relates to an antenna capable of adjusting gains including a first antenna monomer and a second antenna monomer, in which, the first one includes a first radiation unit, the second oneincludes a second radiation unit connected with the first one in a knocked-down way to form several sets of antennas to adjust the gain and radiation pattern of said antenna.

Description

technical field [0001] The present invention relates to an antenna, in particular to an antenna with adjustable gain. Background technique [0002] The main function of the antenna is to convert the energy originally transmitted in the transmission line into the air by using the electromagnetic field formed by the antenna, or vice versa to receive the energy in the air into the transmission line. [0003] The types of antennas can be divided into directional (directional) and omnidirectional (omni-directional) according to the direction of radiation. Users can receive the signal. The important parameters of the antenna include frequency range, radiation pattern, voltage standing wave ratio (VSWR), gain (gain), etc. The gain of the antenna is related to the transmission range of the signal. At the same transmission power or With the same receiving amplifier, the antenna with higher gain can obtain a longer transmission distance. Therefore, when installing the antenna, it is...
