First Embodiment

Fig. 1 is a diagram of a wireless communication apparatus according to an embodiment of the present invention. As shown in Fig. 1, the wireless communication apparatus 10 includes a transceiver 20 and a hanging decoration 30. The transceiver 20 has an antenna 40 and the antenna 40 exposes a metal area 50 to air. The transceiver 20 can receive or transmit an electromagnetic signal in the air through the antenna 40. More specifically, the transceiver 20 can communicate with a remote base station (or a server end) through the electromagnetic signal received or transmitted by the antenna 40.
The hanging decoration 30 is disposed on the wireless communication apparatus 10 and includes a metal conductor 60. When the metal conductor 60 is connected to the metal area 50, the antenna 40 and the metal conductor 60 together can be regarded as another antenna. For example, when the metal area 50 of the antenna 40 is connected to an extension part 110 of the hanging decoration 30, the frequency range of the wireless communication apparatus 10 for receiving and transmitting electromagnetic signal is changed to Very High Frequency (VHF) or Ultra High Frequency (UHF). The frequency range of the VHF is between 30MHz - 300MHz and the frequency range of the UHF is between 300MHz - 3GHz.
It should be noted that although the foregoing embodiment has already described one possible configuration of the wireless communication apparatus 10, anyone skilled in the art may understand that each manufacturer may design the wireless communication apparatus 10 differently. Therefore, the application of the present invention should not be limited only to this one possible configuration. In other words, any design that changes the communication ability of a wireless communication apparatus 10 through a connection between the metal area 50 of an antenna 40 and a metal conductor 40 of the hanging decoration 30 is within the spirit of the present invention. To clarify the spirit of the present invention, one specific embodiment of the present invention is provided as an example in the following.

Second Embodiment

As shown in Fig. 1, the wireless communication apparatus 10 of the present embodiment is a mobile phone, for example. The wireless communication apparatus 10 includes a transceiver 20 and a hanging decoration 30. The transceiver 20 has an antenna 40 and the antenna 40 exposes a metal area 50 to air. The transceiver 20 is an integrated circuit device having communication ability, for example. Furthermore, anyone skilled in the art can design an outer casing 70 that encapsulates and protects the transceiver 20. The outer casing 70 has four keypads 80 and a navigation key 90 for operating the wireless communication apparatus 10. In other embodiment, anyone skilled in the art may design the outer casing 70 with different number of keypads 90, navigation keys or other control devices for operating the wireless communication apparatus 10. In addition, anyone skilled in the art may design a screen 100 coupled to the transceiver 20 for displaying messages produced by the transceiver 20.
The metal conductor 60 of the hanging decoration 30 includes an extension part 110 and a body 120. The extension part 110 is exposed to air and the hanging decoration 30 is connected to the metal area 50 through the extension part 110. For example, the extension part 110 is a metallic latching hook, a magnet or a clip. In the present embodiment, the body part 120 and the extension part 110 are electrically connected. The body part 120 is also a good conductor made of metal for expanding the reception capacity of the antenna.
From another point of view, the antenna 40 and the metal conductor 60 together can be regarded as another antenna (renamed an antenna 41) when the metal area 50 of the antenna 40 is connected to the extension part 110 of the hanging decoration 30. Therefore, the frequency range of the wireless communication apparatus 10 for receiving and transmitting electromagnetic signal is changed. For example, the antenna 40 of the wireless communication apparatus 10 originally receives and transmits the electromagnetic signal at a frequency of about 800MHz. When the metal area 50 of the antenna 40 is connected to the extension part 110 of the handing decoration 30 to form the antenna 41, the frequency range of the wireless communication apparatus 10 for receiving and transmitting electromagnetic signal is changed to between 470MHz - 770MHz. Consequently, the wireless communication apparatus 10 can receive the electromagnetic signal of color television broadcast standard and digital television broadcast laid down by National Television System Committee (NTSC). Moreover, anyone skilled in the art can dispose a number of different hanging decorations 30 on the wireless communication apparatus 10 so that a different hanging decoration can be selected to change the frequency range of the wireless communication apparatus 10 for receiving and transmitting the electromagnetic signal.
As shown in Fig. 1, anyone skilled in the art may design an outer insulating layer 130 to cover the surface of the body part 120 so as to prevent any interference of the electromagnetic signal. For example, a hanging decoration 30 having an outer insulating layer 130 can prevent the body of a user from contacting the body part 120 and lead to the interference of the electromagnetic signal. In addition, the extension art 110 and the body part 120 of the hanging decoration 30 can be made using an elastic metallic material to prevent the user from being hurt by accidental collision. Furthermore, a bearing or a spindle axis can be disposed between the extension part 110 and the body part 120. The bearing or spindle axis allows the hanging decoration 30 to rotate so that the electromagnetic signal coming from different directions can be received as long as electrical connection between the extension part 110 and the body part 120 are maintained all the time.
Those skilled in the art should know that the shape of the antenna of the wireless communication apparatus is closely relate to the ability of the antenna for receiving and transmitting the electromagnetic signal as well as the frequency range of the electromagnetic signal. Therefore, anyone skilled in the art may change the shape of the body part 120 and suitably modify the outer insulating layer 130 in the foregoing embodiment in order to meet a specific requirement. Figs. 2A - 2D are diagrams showing the shapes of body parts and outer insulating layers of hanging decorations according to an embodiment of the present invention. The body part 120 in Fig. 2A is modified to a long and narrow U-shape and the outer insulating layer 130 has a linear shape. The body part 120 in Fig. 2B is modified to a linear shape and the outer insulating layer 130 also has a linear shape. The body part 120 in Fig. 2C is modified to a wider U-shape and the outer insulating layer 130 has an oval shape. The body part 120 in Fig. 2D is modified to a ring shape and the outer insulating layer 130 also has an oval shape.
Fig. 3 is a diagram showing a connecting element according to an embodiment of the present invention. As shown in Figs. 1 and 3, the hanging decoration 30 is normally fixed to a hanging decoration hole 160 of the transceiver 20 through a connecting element 140. The most common connecting element 140 includes, for example, the hanging cord as shown in Fig. 1 or a hooking ring (alternatively called an question-mark hook) as shown in Fig. 3. In the meantime, another part of the connecting element 140 is fixed onto the outer insulating layer 130 of the hanging decoration 30. In other embodiment, anyone skilled in the art may design a base 150 between the connecting element 140 and the outer insulating layer 130. A first layer of the base 150 is connected to the outer insulating layer 130 and a second layer of the base 150 is connected to the connecting element 140 so as to strengthen the firmness of attachment to the hanging decoration 30.
It should be noted that the wireless communication apparatus in the second embodiment also uses a mobile phone as an example for describing the method of implementation. Anyone skilled in the art should notice that the example of a 'mobile phone' used in the second embodiment is only a specific embodiment.
