Technical Field

[0001] This invention relates to an antenna for an electronic device. This antenna can, but is not exclusively, used in the automotive field. The invention also relates to an electronic device incorporating such an antenna. Background Technology

[0002] In the automotive field, an antenna for an electronic device, as known to those skilled in the art, includes a body, a feed pin, and a ground pin, both of which are connected to the electronic support of the electronic device.

Detailed Implementation

[0047] In the following description, functions or structures known to those skilled in the art are not described in detail, as they would obscure the invention with unnecessary detail.

[0048] This invention relates to an antenna 11 for an electronic device 1, the antenna 11 being referenced to... Figures 1 to 7 The following description is provided. In a non-limiting embodiment, electronic device 1 is an electronic device of a vehicle. In a non-limiting embodiment, the vehicle is a motor vehicle. In a non-limiting variant of the embodiment, the motor vehicle has an internal combustion engine, an electric motor, or a hybrid motor. In a non-limiting variant of the embodiment, electronic device 1 is a telematics control unit, hereinafter also referred to as a TCU. This non-limiting embodiment is hereinafter referred to as a non-limiting example.

[0049] The TCU allows vehicles to communicate wirelessly with cloud services, other vehicles, base stations, etc., to exchange information, such as the vehicle's location, speed, engine data, etc., in a non-limiting example.

[0050] In a non-restrictive example, the TCU is used to ensure the safety of drivers and passengers, optimize traffic flow, and make automatic emergency calls in the event of an accident.

[0051] like Figure 1 As shown, the remote information processing control unit 1 includes:

[0052] -Electronic support component 10,

[0053] - Antenna 11,

[0054] -RF (Radio Frequency) Module 12.

[0055] The TCU also includes a housing 13 to receive the electronic support 10, the RF module 12, and the antenna 11.

[0056] The entire antenna 11 is placed on the electronic support 10.

[0057] In a non-limiting embodiment, the electronic support 10 is a printed circuit board assembly, also referred to below as a PCBA.

[0058] The RF module is responsible for communication with other systems. The RF module is a network access device, also referred to hereinafter as NAD. Since the RF module in the TCU is known to those skilled in the art, it will not be described further here.

[0059] Antenna 11 is a cellular antenna. It is configured to receive signals from and transmit signals to a cellular base station. In a non-limiting embodiment, antenna 11 is arranged next to RF module 12. It is independent of the RF module and connected to the RF module via a transmission line. Antenna 11 is responsible for transmitting and receiving wireless communication signals. Therefore, it is configured to be in both receive and transmit modes.

[0060] In a non-limiting embodiment, antenna 11 is made of stamped metal. Figure 2 In the non-limiting embodiment shown, antenna 11 extends along a first direction X and a second direction Y perpendicular to the first direction X, and extends vertically along a third direction Z (referred to as the vertical direction Z) perpendicular to the first direction X and the second direction Y. In the non-limiting embodiment, the dimensions of antenna 11 in the top view are DxD' = 40mm x 40mm (millimeters), and the height h is approximately 14.5mm.

[0061] like Figure 2 and Figure 7 As shown, antenna 11 includes:

[0062] -Main body 110,

[0063] -Power supply pin 111.1,

[0064] - Load pin 111.2,

[0065] - Ground pin 111.3.

[0066] The power supply pin 111.1, the load pin 111.2, and the ground pin 111.3 pass through the electronic support 10 and are soldered to the electronic support 10.

[0067] Antenna 11 is capable of resonating across a wide frequency band: from 617 MHz to 4.2 GHz according to North American standards, and from 703 MHz to 5 GHz according to European standards. It can support more standards, such as those for China and other regions of the world (ROW). Furthermore, antenna 11 is configured to be finely tuned to resonate in the range of 617 MHz to 960 MHz (at lower frequencies). Therefore, antenna 11 is multi-resonant: it has different resonant frequencies. Antenna 11 conforms to the 5G spectrum standard, which runs from 617 MHz to 5 GHz, and has the following frequency band range:

[0068] -617MHz to 960MHz,

[0069] -1.71GHz to 2.69GHz,

[0070] -1.432GHz to 1.517GHz,

[0071] -3.3GHz to 4.2GHz,

[0072] -4.4GHz to 5GHz.

[0073] The different pins of antenna 11 are described below.

[0074] like Figure 2 As shown, the pins extend in the vertical direction Z. In a non-limiting embodiment, they are soldered, press-fitted, connected via springs, or connected via gaskets to the electronic support 10.

[0075] Power supply pin 111.1

[0076] The power supply pin 111.1 allows the transmit and receive antenna 11 to receive the power required.

[0077] like Figure 4 and Figure 5 As shown, in a non-limiting embodiment, the feed pin 111.1 is connected to the matching network 118. In a non-limiting embodiment, the matching network 118 includes two inductors L1 and L2 and a capacitor C1. The matching network 118 improves the impedance of the antenna 11. It allows maximizing the power transmitted from the RF module 12 to the antenna 11 when the antenna 11 is in transmit mode, and maximizing the power transmitted from the antenna 11 to the RF module 12 when the antenna 11 is in receive mode.

[0078] Ground pin 111.3

[0079] Ground pin 111.3 matches the impedance of antenna 11. It allows antenna 11 to be grounded. It provides some inductance to antenna 11.

[0080] like Figure 4 and Figure 5 As shown, in a non-limiting embodiment, ground pin 111.3 is connected to reactor component 114, hereinafter referred to as third reactor component 114. In a non-limiting embodiment, third reactor component 114 is soldered to electronic support component 10. Third reactor component 114 is used to match antenna 11 in certain frequency bands. Matching refers to achieving low reflection of signals received by antenna 11.

[0081] Load pin 111.2

[0082] In a non-limiting embodiment, the load pin 111.2 is connected to various components, such as reactive components and / or switches described later below, so that the antenna 11 can resonate in certain frequency bands.

[0083] Load pin 111.2 is configured to tune the loop portion 1100 of antenna 11, which will be described later below. Tuning the loop portion 1100 means changing its electrical length. Electrical length refers to the length of the loop portion 1100 in terms of wavelength. The physical length of the antenna remains unchanged; only the effective electrical length is changed by altering the value of load pin 111.2. Therefore, load pin 111.2 is also referred to as tuning pin 111.2.

[0084] In a non-limiting embodiment, the load pin 111.2 is arranged away from the power supply pin 111.1.

[0085] In a non-limiting embodiment, it is 13 mm away from the feed pin 111.1. This allows the antenna 11 to be loaded with reactive components remote from the feed pin 111.1, that is, to be loaded with reactive components not connected to the feed pin 111.1. By loading reactive components into the antenna, it means that the antenna 11 is forced to resonate higher or lower than its natural resonance by using reactive components.

[0086] Main body 110

[0087] like Figure 3 As shown, the main body 110 includes:

[0088] - Part 110.1, which extends along the first direction X and the second direction Y, and along the first plane A, and

[0089] - The second part 110.2 extends along the vertical direction Z and along a second plane B that is relatively perpendicular to the first plane A. The first part 110.1 and the second part 110.2 are linked by a fold 110.3.

[0090] In a non-limiting embodiment, when the antenna 11 is metal stamped, the feed pin 111.1, the load pin 111.2, and the ground pin 111.3 appear from the second part 110.2.

[0091] The main body 110 of antenna 11 includes:

[0092] - A ring portion 1100, which extends from the feed pin 111.1 to the load pin 111.2, is configured to tune the antenna 11 to resonate in the first frequency band F1.

[0093] - The first arm 1101 and the first region 1102 of the main body 110 are connected to the ring portion 1100 and are configured to tune the antenna 11 to resonate in the second frequency band F2.

[0094] - The second arm 1103 is connected to the ring portion 1100 and is configured as a tuned antenna 11 to resonate in the third frequency band F3.

[0095] exist Figures 2 to 6 In the first non-limiting embodiment shown, the first region 1102 of the body 110 has a parallelepiped shape. In a non-limiting variation of the embodiment, it has a rectangular shape.

[0096] exist Figure 7 In the second non-limiting embodiment shown, the first region 1102 of the body 110 is the third arm.

[0097] like Figure 3 As shown, the first part 110.1 of the main body 110 of antenna 11 consists of a ring portion 1100, a first arm 1101, a first region 1102, and a second arm 1103. The second part 110.2 allows the ring portion 1100 to be connected to the feed pin 111.1 and the load pin 111.2. The ring portion 1100 is a continuous path that wraps around from the feed pin 111.1 to the load pin 111.2. It includes vertical and horizontal sections.

[0098] The ring portion 1100 is configured to cover a first frequency band F1 so that the antenna 11 resonates at a low frequency. In a first non-limiting embodiment, the first frequency band F1 is between 617 MHz and 960 MHz. It is a low-frequency band. Therefore, the ring portion 1100 causes the antenna 11 to resonate within this first frequency band F1. It should be noted that the antenna 11 resonates only at a sub-part of the frequency band at a time. This selection is achieved by tuning, either by a reactive component or actively using a switch 116, described later, which tunes the antenna 11 to resonate at different sub-parts of the frequency band at a time.

[0099] By adjusting the electrical length of the ring portion 1100, the antenna 11 can be finely adjusted within the first frequency band F1. The electrical length of the ring portion 1100 is modified as follows.

[0100] exist Figure 4In a first non-limiting variation of the illustrated embodiment, the antenna 11 further includes a first reactance component 112 connected to the loading pin 111.2 for fine-tuning the loop portion 1100. In the non-limiting embodiment, the first reactance component 112 is soldered to the electronic support 10. It should be noted that this first non-limiting embodiment has been used... Figure 2 and Figure 3 The first non-limiting embodiment of the antenna 11 shown has been described, but the same applies to other embodiments. Figure 7 The second non-limiting embodiment of the antenna 11 shown is illustrated.

[0101] The first reactance component 112 changes the electrical length of the ring portion 1100. By using the value of the first reactance component 112, the electrical length of the ring portion 1100 can be adjusted, thereby adjusting the antenna resonant frequency within the first frequency band F1.

[0102] In a non-limiting embodiment, the first reactive component 112 is an inductor. It allows for an increase in the electrical length of the ring portion 1100 without additional cost.

[0103] By using the inductor 112 connected to the ring portion 1100, it is ensured that the antenna 11 resonates within a first frequency band F1 between 617MHz and 900MHz, which is the North American standard, or within a first frequency band F1 between 703MHz and 960MHz, which is the European low-frequency standard.

[0104] In a non-limiting embodiment, the inductance value of inductor 112 is between 3 nH (nanohyn) and 2 nH. This solution enables a low-cost antenna 11 because only the regional requirements (Europe or North America) need to be met by changing inductor 112.

[0105] It should be noted that due to the small size of antenna 11, the fundamental frequency resonance of antenna 11 (occurring at the fundamental frequency) is not broadband. The fundamental frequency resonance, or fundamental mode, occurs in the low-frequency band of 800 to 900 MHz. The impedance bandwidth of the fundamental frequency resonance varies between 100 and 150 MHz depending on the tuning. It should be noted that additional resonances caused by harmonics occur at higher frequency bands. This means that for the fundamental frequency of antenna 11 resonance, the harmonics at that fundamental frequency allow antenna 11 to resonate at higher frequency bands.

[0106] The first arm 1101, the first region 1102, and the second arm 1103 allow the antenna 11 to be tuned such that it resonates at frequencies higher than the first frequency band F1. It produces different resonances to cover different higher frequencies. In a non-limiting embodiment, the first arm 1101 and the second arm 1103 are inverted F arms, also known as IFA arms. Figure 7In the second non-limiting embodiment of the antenna 11 shown, the first region 1102 is the third arm, and in the non-limiting embodiment, the third arm 1102 is an inverted F arm.

[0107] The first arm 1101 and the first region 1102 are configured to cover the second frequency band F2, causing the antenna 11 to resonate at a high frequency. In a non-limiting embodiment, the second frequency band F2 is between 1.7 GHz and 2 GHz. The antenna resonant frequency within the second frequency band F2 can be adjusted by adjusting the width and length of the first arm 1101 and the size and thickness of the first region 1102.

[0108] like Figure 3 As shown, in a non-limiting embodiment, the first arm 1101 is located on the same first plane A as the annular portion 1100. In a non-limiting embodiment, the first region 1102 is located on the same first plane A as the annular portion 1100.

[0109] The second arm 1103 is configured to cover the third frequency band F3, causing the antenna 11 to resonate in the high-frequency band. In a non-limiting embodiment, the third frequency band F3 is between 1.3 and 1.6 GHz. The antenna resonant frequency can be adjusted within the third frequency band F3 by adjusting the width and length of the second arm 1103.

[0110] like Figure 3 As shown, in a non-limiting embodiment, the second arm 1103 is located on a third plane A', which is different from and relatively parallel to the first plane A. It is located on the lower plane (third plane A') according to the vertical direction Z. Therefore, the second arm 1103 is located lower than the first arm 1101 and the first region 1102, making it closer to the ground and the electronic support 10. This allows for the addition of some capacitance to the second arm 1103 and improves the matching with the third frequency band F3.

[0111] The harmonic combination of the basic modes of the ring portion 1100 and IFA arms 1101 / 1102 allows the fourth frequency band F4 of the antenna 11 to be covered, enabling the antenna 11 to resonate at high frequencies.

[0112] In a non-limiting embodiment, the fourth frequency band F4 is higher than 2 GHz. The antenna resonant frequency is adjusted within the fourth frequency band F4 by adjusting the width of some regions of the annular portion 1100.

[0113] for Figure 2 The first non-limiting embodiment, in which, as in the non-limiting embodiment, Figure 3As shown, the width w1 of the annular portion 1100 is 9.5 mm, the width w2 is 5.5 mm, the dimensions of the first region 1102 are 11.7 x 14.4 mm, the dimensions of the first IFA arm 1101 are 12.5 x 10.5 mm (square region), the gap between the first arm 1101 and the first region 1102 is 2 mm, and the total length of the second IFA arm 1103 is 31 mm, and it has a tapered shape with a width of 3 mm to 2 mm. Therefore, the component dimensions of the antenna 11 have been adjusted so that the antenna 11 operates for all frequency bands F1 to F4.

[0114] In the same manner as the non-limiting implementation, for Figure 7 In a second, non-limiting embodiment, the component dimensions of the antenna 11 can be adjusted so that the antenna 11 operates for all frequency bands F1 to F4.

[0115] exist Figure 5 In a second non-limiting variant of the illustrated embodiment, antenna 11 includes:

[0116] - First reactance component 112, which is connected to the loading pin 111.2,

[0117] -n second reactance components 113, where n = 1 to N, where N is a natural number, and

[0118] - Switch 116, which is connected to n second reactor components 113.

[0119] It should be noted that it has already been used Figure 2 and Figure 3 The first non-limiting embodiment of the antenna 11 shown illustrates this second non-limiting variation of the embodiment, but it is also applicable to... Figure 7 A second non-limiting embodiment of the antenna 11 shown.

[0120] In a non-limiting embodiment, the first reactance component 112 and the n second reactance components 113 are inductors.

[0121] n second reactor components 113 and switch 116 are connected to load pin 111.2 and grounded.

[0122] In practice, there exists a first electronic trace t1 that connects the first reactive component 112 to the loading pin 111.2 and a second electronic trace t2 that connects the switch 116 to the loading pin 111.2.

[0123] The first reactor component 112 and the n second reactor components 113 are referred to as loading components 112 and 113.

[0124] Switch 116 is configured to tune the loop 1100, such that antenna 11 has n+1 subsets (called sub-bands) F1.1 within the first frequency band F1. n+1 resonance.

[0125] Switch 116 is configured to allow selection of loading components 112, 113.1, 113.2 to load antenna 11, thereby dynamically tuning antenna 11 for different frequency sub-bands within the first frequency band F1. In practice, the switch uses loading components 112, 113 to modify the electrical length of loop 1100. Therefore, tuning of loop 1100 results in tuning of antenna 11. In a non-limiting embodiment, tuning of antenna 11 is accomplished using either the first reactance component 112 or a combination of the first reactance component 112 and the second reactance component 113.

[0126] Therefore, the switch 116 is configured to employ:

[0127] - At the first position p1, the switch is open, causing the annular portion 1100 to tune in the first subset F1.11.

[0128] - At position n+1 (pn+1), the switch is turned on (also called enabled), causing the ring portion 1100 to be in the (n+1)th subset F1.1 n+1 Tuning.

[0129] In a non-limiting embodiment, antenna 11 includes two second reactive components 113, referred to as 113.1 and 113.2, and connected to switch 116. In this case, as... Figure 6 As shown, switch 116 is configured to use:

[0130] - At the first position p1, the switch is off, and at the first position p1, the antenna 11 is loaded with the first reactive component 112 via the loading pin 111.2 so that the first subset F1.11 resonates, and thus the antenna 11 resonates.

[0131] - Second position p2, where the switch is turned on (also known as enabled), and at this second position p2, the antenna 11 is loaded via the loading pin 111.2 with the first reactive component 112 and one of the two second reactive components (here, 113.1) so that the second subset F1.12 resonates, and thus the antenna 11 resonates.

[0132] - Third position p3, where the switch is turned on (also known as enabled), and at this third position p3, the antenna 11 is loaded with the first reactance component 112 and another of the two second reactance components (here 113.2) via the loading pin 111.2 so that the third subset F1.13 resonates, and thus the antenna 11 resonates.

[0133] In a non-limiting embodiment, switch 116 is controlled by NAD to employ different positions p1 and pn+1.

[0134] The first position p1 allows the tuning ring 1100 to resonate, such that the antenna 11 resonates in the first subset F1.11, which, in a non-limiting embodiment, is between 600MHz and 700MHz. Since the first position p1 in the non-limiting embodiment is the open position of switch 116, the second reactance component 113 is a bypass component that is responsible for antenna tuning when switch 116 is open.

[0135] The second position p2 allows the tuning ring 1100 to resonate at the second subset F1.12, which, in a non-limiting embodiment, is between 650 MHz and 850 MHz.

[0136] In a non-limiting embodiment, the third position p3 allows the tuning ring 1100 to resonate the third sub-band F1.13 of the antenna 11 between 700MHz and 900MHz.

[0137] The sum of the three subsets F1.11, F1.12 and F1.13 corresponds to the first frequency band F1.

[0138] It should be noted that tuning based on different national requirements can be accomplished without switch 116. Here, Figure 5 This second non-limiting variant of the embodiment using switch 116, as shown, allows the electronic device 1 to actively fine-tune when operating in a particular country. This improves the performance of the antenna 11 compared to a passive antenna 11 (without switch 116), in which bandwidth is more limited and performance is reduced. For countries other than Europe or North America, the reactance component can be selected with the correct value for the reactance component to have the correct national frequency band.

[0139] It should be understood that the present invention is not limited to the above applications, and implementations, modifications, and variations are possible without departing from the scope of the invention. All statements herein that enumerate the principles, aspects, and embodiments of the invention, as well as specific examples thereof, are intended to cover their equivalents.
