DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS [0022] Figure 1 shows a block diagram of a method for enhancing signal strength of a wireless signal in a mobile communication device in accordance with the present invention. In accordance with the present invention, a metal element LI of any configuration or shape is utilized and is connected to one mobile communication device L4 (later mobile phone) via gap-coupled means L2 in order to alter frequency effect of an antenna unit installed in the mobile phone for enhancing signal strength of a wireless signal transmitted or received by the mobile phone L4. The gap-coupling means L2 includes a step of directly connecting the metal element to the mobile phone L4. Preferably, the mobile phone L4 further includes a mobile casing (mobile protection casing) L3. The gap coupling means L2 includes a step of connecting the metal element LI to the mobile casing L3, hence the metal element LI is connected to the mobile phone L4. [0023] Referring to Figures 2A-2D, wherein Figure 2A is a perspective view illustrating how the metal element, in the form of an elongated metal plate 4 with rectangular cross-section, is mounted directly on the front surface 31 of the mobile phone 3 near the upper right side thereof in accordance with the present invention in a first way; Figure 2B is a perspective view illustrating how the elongated metal plate 4 is mounted directly on a lateral side surface 33 of the mobile phone 2 in accordance with the present invention in a second way; Figure 2C is a perspective view illustrating how the elongated 6 metal plate 4 is mounted directly on the rear surface 32 of the mobile phone 3 near the lower left side thereof in accordance with the present invention in a third way; and Figure 2D is a perspective view illustrating how an L-shaped metal plate 4 is mounted directly on the lateral side surface 33 of the mobile phone 3 in accordance with the present invention in a fourth way. Note that mounting of the metal plate 4 on the mobile phone 3 can be accomplished via adhesion means, but should not be limited only thereto. Another factor to note is that after connection or assembly, the metal plate 4 has at least an area overlapped with the mobile phone 3. The metal plate 4 or metal rod may have a cylindrical cross section or a rectangle but the shape should not be limited to any configuration. [0024] In those embodiments illustrated in Figures 2A-2D, the metal plate 4 may have a configuration or any shape and can be connected to any position of the mobile phone 3. The scope of the present invention should not be limited to the above four embodiments only. The mobile phone 3 can be of any brand or type and is produced from any manufacturing company. The materials for fabrication of the mobile phone and the mobile casing generally include plastic materials and metals in the present invention. [0025] The metal plate LI of any configuration or shape is mounted to the mobile phone L4 or the mobile casing L3 via the gap-coupled means 2 in those embodiments. The metal plate 4 can be directly connected to the mobile phone or the mobile casing. Alternately, in other embodiments, the metal plate 4 can be connected to the mobile phone or the mobile casing (mobile phone protection shell) via a pull strip 2, as best shown in Figures 3A and 3B, where the mobile casing is formed with a slide groove for receiving the pull strip in such a manner that the pull strip is extendible slidably, outwardly from and retractable into the mobile casing so as to adjust the transmitting and receiving frequency of the antenna unit installed in the mobile phone. [0026] Figure 3A is a perspective view illustrating how the metal plate is mounted on the mobile casing in accordance with the present invention in a first way. The mobile phone 1 preferably includes the mobile casing (mobile phone protection shell), which has an accommodation plate 12 for receiving the mobile phone thereon and a lateral portion 11 extending outwardly from a periphery confining the accommodation plate 12 so as to 7 enclose and surround the mobile phone at least partially once the mobile phone is placed on the accommodation plate 12. [0027] The accommodation plate 12 of the mobile casing is further formed with an oblong opening at an upper portion thereof. The oblong opening is confined by two opposite side walls cooperatively defining a slide groove structure 122. The accommodation plate 12 of the mobile casing is further formed with an exposure opening 121 at a lower portion thereof; that extends along a direction transverse to the slide groove structure 122 and that exposes the view finding window (see Figures 2C and 2D) of a camera device in the mobile phone after assembly of the mobile casing and the mobile phone. [0028] The lateral portion 11 of the accommodation plate 12 is further formed with two lateral openings 111 such that after assembly of the mobile casing with the mobile phone, a portion (including volume-control key, suspending key, earphone socket and charging hole) of the mobile phone is exposed to facilitate the user to operate the respective operation key. [0029] Note that formation of the exposure opening 121 and the lateral opening 111 in the accommodation plate 12 should be conducted in such a way to complement with the components of the mobile phone, such as the camera lens, earphone socket and charging hole. However, if the mobile phone fabricated by the method of the present invention is not equipped with above-stated widgets, formation of the exposure opening 121 and the lateral opening 111 in the accommodation plate 12 can be neglected. [0030] The pull strip 2 is mounted slidably in the slide groove structure 122, has a planar inner side surface facing the mobile phone and a planar outer side surface opposite to the inner side surface. In this embodiment, the metal plate 21 is mounted on one of the inner and outer side surfaces of the pull strip 2, thereby movable together with the pull strip 2 with respect to the accommodation plate 12 of the mobile casing. Alternately, the metal plate 21 can be embedded within the pull strip 2 so as to be movable together therewith. Mounting of the metal plate 21 on the pull strip 2 is accomplished via the adhesive means, but the scope should not be limited only thereto.
8 [0031] Figure 3B is a perspective view illustrating how the metal plate 21 is mounted on the accommodation plate 12 of the mobile casing in accordance with the present invention in a second way, wherein the lower portion of the accommodation plate 12 is formed with the lateral portion 11 enclosing or surrounding the periphery of the accommodation plate 12. [0032] The accommodation plate 12 of the mobile casing is further formed with an exposure opening 121 at upper and lower portions thereof so that after assembly of the mobile casing and the mobile phone, the view finding window (see Figures 2C and 2D) of a camera device in the mobile phone is exposed to an exterior environment. [0033] The lateral portion l Ithe accommodation plate 12 is formed with an oblong opening at the lower portion thereof. The oblong opening is confined by two opposite side walls cooperatively defining the slide groove 112. The lateral portion 11 of the accommodation plate 12 is further formed with two lateral openings 111 at the upper portion thereof such that after assembly of the mobile casing and the mobile phone, a portion (including volume-control key, suspending key, earphone socket and charging hole) of the mobile phone is exposed to the exterior to facilitate the user to operate the respective key. [0034] The pull strip 2 is mounted slidably in the slide groove 112, has a planar inner side surface facing the mobile phone and a planar outer side surface opposite to the inner side surface. In this embodiment, the metal plate 21 is mounted on the outer side surface of the pull strip 2, thereby movable together with the pull strip 2 with respect to the accommodation plate 12 of the mobile casing. Mounting of the metal plate 21 on the pull strip 2 is accomplished via the adhesive means, but the scope should not be limited only thereto. [0035] Figures 3A and 3B illustrate two embodiments of metal plate mounting method relative to the mobile casing, but the scope should not be limited only to the two methods. The mounting of metal plate relative to the pull strip should not be limited to any specific side surface and position. Alternately, the pull strip 2 can be formed with a retention recess, into which the metal plate is attached thereinto. An auxiliary metal plate is 9 used for shielding the pull strip 2 in such a manner that the pull strip 2 is not visible from an exterior environment. In addition, the pull strip 2 is designed to be slidable to couple with the antenna to achieve the ultimate frequency efficiency and rate. Hence, the pull strip is not always designed as slidable. For instance, the metal plate 21 can be directly mounted on the mobile casing without the need of the pull strip in order to achieve the ultimate frequency efficiency also. [0036] While using the mobile phone installed with the mobile casing of the present invention via the gap-coupled means, and if the user feels the surfing or reception of wireless signals is not sufficiently enough, he can extend the pull strip 2 outward to a certain degree, under which the metal plate 21 on the pull strip 2 alters and enhances the signal strength of the wireless signal transmitted or received by the antenna unit of the mobile phone. The enhancing signal strength of received wireless signal may be achieved in some mobile phone of other type without the need to extending the pull strip outward from the mobile casing. [0037] In order to achieve the ultimate frequency efficiency, the formation of the retention recess and the pull strip should complement to the configuration of the antenna unit. As described above, so long as the antenna unit can enhance the signal strength of the received wireless signal, formation of the retention recess and the pull strip should not be restricted to any position and configuration. [0038] In wireless signal transmission, VSWR (Voltage Standing Wave Ratio) unit is used to measure the impedance in transmission line, and is represented by X: 1; or simply X. The smaller the value of X becomes (i.e. when the value of X approaches 1), the lesser the reflected wave power in the transmission cable. In short, an ideal transmission line has SWR 1:1. To prove the enhanced signal strength in a mobile phone provided with the signal-strength enhancing structure of the present invention relative to a conventional mobile phone, an experiment is conducted and the result is shown in Figure 4, wherein the graph shows VSWR vs. Frequency of the prior art and present mobile phones. As illustrated in Figure 4, when operated under any frequency range, the prior art mobile phone generates VSWR higher than a mobile phone provided with the signal-strength enhancing structure of the present invention. For instance, when operating under frequency 10 range of 1600 MHz, the present mobile phone has 2-3 lesser VSWR when compared with the prior art mobile, which has 6 VSWR. When operating under frequency range of 2000 MHz, the present mobile phone has 1.9 VSWR while the prior art mobile has 3 VSWR. [0039] Whilethe invention has been described in connection with what is considered the most practical and preferred embodiments, it is understood that this invention is not limited to the disclosed embodiments but is intended to cover various arrangements included within the spirit and scope of the broadest interpretation so as to encompass all such modifications and equivalent arrangements. [0040] Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. [0041] The reference to any prior art in this specification is not, and should not be taken as, an acknowledgment or any form of suggestion that the prior art forms part of the common general knowledge.
