Mobile communication device

The invention relates to a mobile communication device, in particular to a mobile communication device with a magnetic antenna.

In recent years, due to the practical use of wireless communication and the popularization of technology products, the breakthrough and development of the communication industry can be said to be changing with each passing day. Various communication products and wireless communication equipment have been widely used in daily life, resulting in mobile phones in daily life. Life is so popular that it is quite common for modern people to have two or three mobile phones.

At the same time, with the trend of miniaturization, the volume of mobile phones is of course smaller and smaller, and it is getting lighter and lighter. The overall size of the antennas that are configured is of course reduced, but since the antenna characteristics are usually fixed, For example, the field type and gain radiated by the antenna, so that the mobile phone becomes smaller and smaller, the gain of the antenna is easily insufficient, which indirectly causes problems such as poor communication quality.

In view of this, how to use the low-cost, energy-saving and simple method to enhance the operational performance of the antenna of the mobile phone, and thus improve the communication quality, has become an important issue. With the research and the spirit of perseverance, I finally conceived the "mobile communication device" of this case. The following is a brief description of the case.

The invention is disposed on the side of the antenna of the mobile communication device or the wireless transmit/receive unit (WTRU), and the appropriate magnetic material is disposed. By adjusting the distance between the magnetic material and the antenna, the antenna can refraction in multiple frequency bands. The effect is such that a better field pattern can be produced in different frequency bands while increasing its gain value.

For mobile communication devices or WTRUs with poor reception, such as mobile phones or mobile phones, mobile devices can be used to place magnetic materials on one side of the mobile phone antenna, thereby exerting the advantages of "magnetic antenna" high radiation gain and increasing antenna radiation beam spatial angle. The quality of the receiving can be improved, and the external magnetic material enhances the radiant energy, so that the mobile phone can reduce the transmission power when designing, the energy consumed by the battery is reduced, and the standby time of the mobile phone can be relatively increased.

The present invention will be fully understood by the following examples, so that those skilled in the art can do so. However, the implementation of the present invention may not be limited by the following embodiments.

The "mobile communication devices" in this document include but are not limited to folding mobile phones, split-type mobile phones, hatchback mobile phones, slide-type mobile phones, dual-screen mobile phones, rotary mobile phones, vertical mobile phones, touch mobile phones, smart phones. "Multimedia mobile phone, dual screen mobile phone or camera phone"; and "Wireless Transmission/Receive Unit (WTRU)" includes but is not limited to user equipment, mobile station, fixed or Mobile subscriber unit, pager or any other device that has an antenna and is capable of operating in a wireless communication environment.

By providing magnetic material at a suitable location beside the antenna of the mobile communication device or the WTRU, the shielding property of the magnetic material can be utilized to enhance the overall gain of the antenna, and the field pattern of the antenna can be appropriately changed.

Please refer to the first figure, which is a schematic diagram of a first embodiment of the mobile communication device of the present invention. The mobile communication device 10 in the first figure is exemplified by a classic slide type mobile phone, which is a multi-band mobile phone, preferably allowing operation in a bandwidth of 1 G-Hz to 2.6 G-Hz, and having the first The main body 11 and the second body 12, the second body 12 is slidably electrically connected to the first body 11 through a sliding mechanism (not shown), and a display screen is usually provided on the second body 12, first The main body 11 is provided with an alphanumeric keyboard, and the first body 11 further includes components such as a wireless communication circuit module, a signal processing module, and a battery 13, and an antenna is disposed on one end of the first body 11. 14. In the embodiment, a planar inverted-F antenna (PIFA) is taken as an example, and a magnetic material M is disposed at a position beside the antenna 14 to enhance the gain of the antenna 14, the magnetic material. Preferably, its relative magnetic permeability μ _r >10.

The magnetic material itself can also be regarded as an absorber, which can be used to absorb radio waves, preferably a soft block composed of a magnetic substance and a plastic, and the absorbing effect thereof is composed of its thickness and magnetic substance. Density-related, and also closely related to the relative permeability, so the magnetic material M itself has a variety of parameters, including the relative permeability coefficient μ _r , relative dielectric coefficient ε _r , thickness t, length L, width W By adjusting the above parameters, the antenna 14 can be made to have different refraction and reflection effects, thereby changing the field type and gain of the antenna 14, by adjusting the parameters above, and the parameters of the unevenness and the distance d between the magnetic material and the antenna.

It should be noted that the mobile communication device 10 in the first figure is located at the center of the three-dimensional Cartesian coordinate, and the mobile communication device 10 is used as the original point of the card coordinate, which can be separated into x. The axis, the y-axis and the z-axis, the antenna 14 is located on the xy plane formed by the x and y axes, and the distance d between the magnetic material M and the antenna 14 is changed along the z-axis, and the angle θ is defined. For the angle between a point on the xz plane and the x-axis, the angle θ ranges from 0° to 360°.

Please refer to the second figure, which is a schematic diagram of a second embodiment of the mobile communication device of the present invention. The difference between the second embodiment and the foregoing first embodiment is that the first body 21 of the mobile communication device 20 in the second figure is compared with the first body 11 of the mobile communication device 10 in the first figure. The height is appropriately elongated to form a surplus space at the upper end of the first body 21 to accommodate the antenna 24 and the magnetic material M, thereby facilitating integration of the antenna 24 and the magnetic material M in the mobile communication device. Among the first bodies 21 of 20.

In the second embodiment, the magnetic material M used therein preferably has a relative magnetic permeability μ _r = 20, a relative dielectric constant ε _r = 60, a thickness t = 0.85 mm, a length L = 46 mm, and a width. W=10 mm and the distance between the magnetic material M and the antenna 14 is d=13.8 mm. With the above configuration, the magnetic material M can simultaneously enhance the gain of multiple frequency bands of the mobile communication device 10; it is worth noting that The implementation of the magnetic material of the present invention is not limited by the parameters described above.

Please refer to the third figures (a) and (b), which are schematic diagrams of the normal antenna mode and the magnetic antenna mode of the present invention, respectively. The antenna 34 is disposed on the top end of the body 31 of the mobile communication device 30 disclosed in the third figures (a) and (b), and the magnetic material M is movably coupled to the body 31 via the moving mechanism 36. The mechanism 36, the magnetic material M can be moved from the middle portion of the body 31 to the top end of the body 31 to block the antenna 34 at the top end of the body 31, thereby changing the field type of the mobile communication device 30 and enhancing its gain.

Alternatively, it is preferable to consider the combination of the antenna 34 and the magnetic material M as a switched magnetic antenna. When the magnetic material M is located at the middle portion of the body 31, away from the antenna 34, it is equal to the antenna 34 and the magnetic material M. The combination is in the normal antenna mode, and its field type and gain performance is the same as that of the conventional mobile phone antenna; when the magnetic material M moves to the top of the body 31 and shields the antenna 34, it is equal to the antenna 34 and the magnetic material M. The combination is in magnetic antenna mode, the field pattern will change and its gain will be enhanced. The switched magnetic antenna composed of the antenna 34 and the magnetic material M can be arbitrarily switched between the normal antenna mode and the magnetic antenna mode.

In the communication frequency bands 1.035G-Hz, 2.1G-Hz and 2.62G-Hz, the original mobile communication device (without magnetic material M) and the mobile communication device using magnetic antenna are measured respectively, and the gain at various angles is measured. A planar field pattern of the presence or absence of a magnetic material in each frequency band can be obtained. The fourth figure discloses the active field type of the mobile communication device of the present invention in the 1.035G-Hz frequency band and the field type enhanced by the magnetic antenna; the fifth figure discloses the mobile communication device of the present invention in 2.1G- In the Hz frequency band, the original field type and the field pattern enhanced by the magnetic antenna; the sixth figure discloses the mobile station of the present invention in the 2.62G-Hz frequency band, and the original field type and the field enhanced by the magnetic antenna type.

According to the disclosure of the fourth to sixth figures, the magnetic antenna field type is reduced by about 0.29344 dB on the average field of the mobile phone in the frequency band 1.035 G-Hz, indicating that the mobile phone radiation is slightly weakened. However, the magnetic antenna field type greatly increases the gain value when the frequency band is 2.1G-Hz, and the radiation field type increases the gain at the same time, and increases the gain value by 1.87dB at θ=180°, indicating that the mobile phone radiation Significantly enhanced, it is conducive to the signal transmission and reception of the antenna. The magnetic antenna field type increases the gain value in the direction of θ=180° compared with the original field type of the mobile phone in the frequency band 2.62G-Hz, and the radiation field type can also diffuse outward to increase the gain value, and can increase the spatial angle of the radiation beam. The gain value can be increased by 0.57dB at θ=180°, which means that the radiation of the mobile phone is enhanced and the spatial angle of the antenna radiation beam becomes larger, which is more conducive to the signal transmission and reception of the antenna. By arranging the above data, the results of Tables (1) and (2) can be further obtained, wherein the definition of the angle θ is as described above.

Comparing the results in Table (1) and Table (2), it can be seen that the total average gain of θ=0°~360° and the total average gain of θ=180° are slightly smaller than the total average gain value of the magnetic antenna in the frequency band 1.035G-Hz. In addition, the other two bands (2.1G-Hz, 2.62G-Hz) can greatly increase the total average gain of the antenna, which means that the magnetic material can actually improve the overall average gain. In terms of the total average gain of θ=180°, although the total average gain of 0.38dB is sacrificed in the frequency band 1.035G-Hz, it is confirmed that the frequency band 2.1G-Hz greatly increases the total average gain of 1.87dB and the frequency band 2.62G-Hz increases. The average gain is 0.57dB.

The magnetic antenna described above can be used as an antenna suitable for any mobile communication device for wireless communication. As long as the magnetic material is applied to one side of the antenna, it can be combined into a "magnetic antenna", thereby enhancing the gain and increasing the antenna radiation. Beam space angle, save power and extend standby time.

The present invention is a rare and incomprehensible invention, and the above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto. That is to say, the equivalent changes and modifications made by the applicant in accordance with the scope of the patent application of the present invention should still fall within the scope of the patent of the present invention. I would like to ask your review committee to give a clear explanation and pray for it.
