Problems solved by technology

However, the impedance matching network additionally increases the feeder design of the electronic system and increases the area of ​​the radio frequency system. At the same time, the matching network also introduces a lot of energy loss, which is difficult to meet the system design requirements of modern communication systems with low power consumption.

Embodiment 2

[0050] Such as Figure 5 As shown, in this embodiment, spaces 53 and 54 for embedding capacitive electronic components are preset between the first feeder 2 and the first metal sheet 4, and between the second feeder 3 and the first metal sheet 4, The preset position embedded in the space of the electronic component may be any position between the first feeder 2 and the first metal sheet 4 , and between the second feeder 3 and the first metal sheet 4 . Figure 4 The middle space 53 and the space 54 are spaces for embedding capacitive electronic components in this embodiment. There is a certain capacitance between the first feeder 2, the second feeder 3 and the first metal sheet 4, which is adjusted here by embedding capacitive electronic components. For the signal coupling between the first feeder 2, the second feeder 3 and the first metal sheet 4, use the formula: It can be seen that the capacitance value is inversely proportional to the square of the operating frequency, so...

Embodiment 3

[0052] Such as Image 6 As shown, in this embodiment, a space for embedding inductive electronic components and / or resistors is reserved on the first metal wiring 42 of the first metal sheet, and the space for embedding electronic components is not limited to the one shown in the figure. Space 55 and space 56, and other locations as long as the conditions are met. The purpose of embedding inductive electronic components here is to increase the inductance value of the internal resonant structure of the first metal sheet, thereby adjusting the resonant frequency and working bandwidth of the antenna; same as the first embodiment, the purpose of embedding resistors here is to improve The radiation resistance of the antenna. As for embedding inductive electronic components or resistors, it depends on the needs. In addition, wires are used to short-circuit in the space where electronic components are not embedded.

Embodiment 4

[0054] Such as Figure 7 As shown, in this embodiment, a space for embedding capacitive electronic components is reserved on the first microgroove structure 41 , and the space connects the first metal wires 42 on both sides. The space for embedding electronic components is not limited only to the Figure 5 The space 57 given in , other locations are all available as long as the conditions are met. Embedding capacitive electronic components can change the resonance performance of the first metal sheet, and ultimately improve the Q value and resonance operating point of the antenna. As common knowledge, we know that the relationship between the passband BW, the resonant frequency wo, and the quality factor Q is: BW=wo / Q. This formula shows that the larger the Q, the narrower the passband, and the smaller the Q, the wider the passband. In addition: Q=wL / R=1 / wRC, wherein, Q is the quality factor; w is the power frequency when the circuit resonates; L is the inductance; R is the ...

Abstract

The invention discloses a mobile phone, which comprises a printed circuit board (PCB) and an antenna connected with the PCB. The antenna comprises a dielectric substrate, a first metal sheet and a second metal sheet. A first feeder line and a second feeder line are arranged in a way of enclosing the first metal sheet. A third feeder line and a fourth feeder line are arranged in a way of enclosing the second metal sheet. The first and second feeder lines feed signals in the first metal sheet in a coupling way. The third and fourth feeder lines feed signals in the second metal sheet in a coupling way. A first micro-channel structure is hollowed in the first metal sheet to form first metal wiring on the first metal sheet. A second micro-channel structure is hollowed in the second metal sheet to form second metal wiring on the second metal sheet. The first and third feeder lines are electrically connected. The second and fourth feeder lines are electrically connected. Spaces are formed in advance in the antenna, and electronic components are embedded into the spaces. The requirements of miniaturization, low working frequency and broadband multimode for the antenna of the mobile phone are met, and a novel multifunctional service platform is provided for the mobile phone.

Description

technical field [0001] The invention relates to a mobile device, in particular to a mobile phone. Background technique [0002] Multi-function, miniaturization and low radiation damage are the inevitable trend of mobile phones, and the mobile phone antenna directly determines the performance of receiving radiation signals when the mobile phone is moving, affecting the performance of mobile phone calls or transmitting data information, so the quality of the mobile phone antenna is very likely Determine the living space of mobile phones in the market. However, on the premise of maintaining the necessary radiation efficiency and gain of the mobile phone, it will be a meaningful thing to minimize the size of the mobile phone antenna. [0003] Existing mobile phone antennas are mainly designed based on the radiation principle of an electric monopole or dipole, such as the most commonly used planar inverted F antenna (PIFA). The radiation operating frequency of the above-mention...
