  Referring to FIG. 3A, the main body 1 of the mobile phone shell is molded according to the appearance of the mobile phone and forms a protective shell for resting the mobile phone. The bottom of the main body 1 is the rest surface 12 and is wound around the rest surface 12. The part to be molded is the side surface 11.

  A rectangular hole is formed in the middle of the upper half of the rest surface 12 of the main body 1, a groove 122 for forming a slide rail structure is formed on the two sides of the hole, and a separate hole 121 is formed on the rest surface 12. After connecting the mobile phone to the hand, the camera lens of the mobile phone should not be blocked.

  A hole 111 on at least one side surface is formed on the side surface 11 of the main body 1 to provide a space, and the user presses a button such as a standby button or an audio control key after the mobile phone is connected to the mobile phone shell and used. Devices such as earphones and chargers can be inserted.

  It should be noted that the hole 121 and the side hole 111 are formed in accordance with a device included in a mobile phone, for example, a camera lens, an earphone hole, a charger hole, and the like. If not, the present invention can be molded in a form that does not have the holes 121 and the side holes 111.

  The tab 2 is shaped according to the rectangular appearance of the sliding groove 122, forming a design that can be combined with a slide rail structure on its side, allowing the tab 2 to slide between the grooves 122, the tab 2 The plane that faces the position where the mobile phone is placed is the first surface, and the plane that faces the first surface is the second surface. The tab 2 is separately provided with a metal piece 21 on the first surface, of which the installation method is not limited to this, but can be bonding with an adhesive.

  Referring to FIG. 3B, the main body 1 of the mobile phone shell is molded according to the appearance of the mobile phone, and a protective shell that can rest the mobile phone is formed. The bottom of the main body 1 is the rest surface 12. The side surface 11 is a part that is molded so as to surround the periphery.

  The main body forms a hole 121 in the resting surface 12 and connects the mobile phone shell to the mobile phone so that the camera lens of the mobile phone is not blocked.

  The main body 1 is formed with a rectangular hole in the lower right half of the side surface 11 and a groove 112 for forming a slide rail structure on the two hole sides. At least one side hole 111 is separately formed on the side surface 11 of the main body 1 to provide space, and the user presses a button such as a standby button or an audio control key after the mobile phone is connected to the mobile phone shell and used. Devices such as earphones and chargers can be inserted.

  The tab 2 is shaped according to the rectangular appearance of the sliding groove 112, forming a design that can be combined with a slide rail structure on its side, the tab 2 can be slid between the sliding grooves 112, and the tab 2 The plane facing the position where the mobile phone is placed is the first surface, and the surface facing the first surface is the second surface. The tab 2 is separately provided with a metal piece 21 on the first surface, of which the installation method is not limited to this, but can be bonding with an adhesive.

  It should be understood that the two embodiments of FIGS. 3A and 3B illustrate the use of a sliding groove structure as an implementation for placing a metal piece on a mobile phone shell, and the implementation of the present invention. The examples are not limited to the above two methods. Of these, the metal piece is not limited to be placed on an arbitrary part on the main body 1, which is formed into an arbitrary shape on the sliding groove structure, and the metal piece 21 is limited to be placed on the first surface of the tab 2. Alternatively, it can be installed on the second surface, or a groove is formed in the tab 2, and after inserting the metal piece 21, the metal piece is separately covered and fused, and it is used to install it inside the tab. It can be made invisible from the outside. Also, designing the tab 2 to be slidable is used to combine the antenna frequencies and achieve the optimum effect, so that the tab 2 does not necessarily require sliding for each different type of mobile phone. In a situation where it is not necessary to achieve the optimum effect through the sliding of the tab 2, the metal piece 21 can be installed directly in the main body 1 without going through the tab 2.

  When the user feels that the signal reception of the mobile phone wireless network, the mobile phone mobile network, the Bluetooth transmission device and the communication device is not good when using the mobile phone combined with the mobile phone shell of the present invention, the tab 21 is pulled to a fixed point. By changing the frequency response of the antenna via the metal piece on the tab 21 and increasing the signal reception capability of the mobile phone wireless device, of which pulling to a fixed point depends on the stability of various types of mobile phones There is also a possibility that the optimum signal receiving capability can be achieved without having to pull the tab 21.

  It should be understood that in order to achieve the optimum performance of the present invention, the groove and the tab need to be shaped according to the antenna position of the mobile phone, and are used to generate the optimum effect. As described in the column, the tab extending over the concave groove is not limited to be formed in accordance with the signal receiving antenna, and both can be formed at an arbitrary position, which similarly increases the effect of signal reception.

  The voltage standing wave ratio (VSWR) is an index unit for measuring the severity of impedance mismatch, and is usually displayed as X-to-one or directly as X. The smaller the value of X, the closer to 1, indicating that the resistance values of all the members in the system are substantially the same, that is, closer to the ideal state. In order to prove that the present invention has the effect of increasing the signal reception performance, the applicant of the present invention has determined that the mobile phone not adopting the structure of the present invention and the VSWR of the portable telephone adopting the structure of the present invention. (See FIG. 4) is actually measured. As can be seen from FIG. 4, at various frequencies, the VSWR of the antenna before using the present invention is higher than the VSWR after using the present invention. For example, at a frequency of 1600 MHz, the VSWR is reduced from 6 to about 2.3, and a frequency of 2000 MHz. The VSWR is reduced from 3 to about 1.9. The performance of the present invention can be easily understood through this figure.
