Problems solved by technology
[0004] This antenna manufacturing process has a problem. Because the heat resistance of the inner film 24 is not enough, when the outer film 25 is injected, the inner film that has been injected is often eccentric or deformed, which sometimes not only causes appearance defects, but also Seriously, it causes the deformation of the poles 22 and the coil 23 on the inner membrane, which changes the radio frequency performance of the antenna, affects the transmission and reception performance of the antenna, and ultimately affects the overall performance of the mobile phone

Embodiment Construction
[0036] see below Figure 3A to Figure 3E A specific embodiment of the manufacturing method of the external antenna of the present invention is described in detail in the step-by-step manufacturing process.
[0037] First, the manufacturing method of the external antenna of the present invention prepares a Figure 3A As shown in the coil frame 31, the shape of the coil frame 31 can be determined according to actual needs, usually a cylindrical shape can be used, and a spiral groove 32 is provided on the outer surface of the coil frame 31, and the spiral groove 32 is used for spinning in subsequent steps. Into the coil (will be described later), therefore, the setting parameters of the helical groove 32, such as the pitch, etc. are determined according to the requirements of the coil. The bobbin 31 also has a cavity 33 which is open at one end downward and is in an open form.
[0038] Then, prepare a Figure 3B As shown in the fixed seat 41 , the fixed seat 41 defines a throu...

The present invention relates to an external antenna of handset and its manufacture method. Said method includes the following steps: preparing a coil frame, the described said antenna frame has a hollow cavity, on its external surface a spiral groove is set; preparing a fixing seat, said fixing seat has a through hole; connecting the described coil frame and described fixing seat, and making the through hole of the described fixing seat be communicated with the hollow cavity of the described coil frame; screwing the coil into the spiral groove of the described coil frame and inserting a steel rod into the through hole of the described fixing seat and making it be extended into the hollow cavity interior of the described coil frame; utilizing injection moulding process to form external film on described coil frame and partial fixing seat; drawing out the described steel rod; and inserting a polar body into the through hole of described fixing seat and making it be extended into the hollow cavity of the described coil frame.
Description
technical field [0001] The present invention relates to an antenna structure, in particular, relates to the improvement of the structure of the mobile phone's external antenna and the manufacturing method of the external antenna. Background technique [0002] figure 1 The structure of a currently common external antenna for mobile phones is shown. Such as figure 1 As shown, the external antenna includes a fixing seat 21 , a pole 22 , a coil 23 , an inner membrane 24 and an outer membrane 25 . The pole 22 is located in the inner membrane 23, figure 1 It is shown that the pole 22 is a needle-shaped metal wire, and in other structures, the pole 22 also adopts the form of a helical coil. The coil 23 is wound on the outer surface of the inner membrane 24, and the inner membrane 24 equipped with the pole 22 and the coil 23 is connected to the fixed seat 21, and the outer membrane 25 is sleeved on the inner membrane 24 including the pole 22 and the coil 23, and Contains cover ...
