Background Art
[0002] Waveguide antennas or waveguide slot antennas are currently state-of-the-art in applications such as radar sensors and communication systems. Those antennas have desirable characteristics such as a small standard deviation in their performance (i.e., gain and phase) compared to typical microstrip antennas, and are flatter and easier to integrate into devices than typical horn antennas.
[0003] U.S. Patent Application Publication No. 20200220273A1 describes a waveguide antenna device including a layer of non-radio frequency (RF) material on the underside of a laminate and a first layer of conductive material formed on the upper surface of the layer of non-radio frequency material on the underside of the laminate. U.S. Patent Application Publication No. 20210382135A1 describes a vehicle radar detection system including a radar sensor disposed in a vehicle.
[0004] An object is to provide a system and a method of mounting a set of radio frequency transceiver assemblies. The underlying object of the present invention is solved by the features of the independent claims.
Summary of the Invention
[0005] The present invention relates to a set of radio frequency transmitting and receiving assemblies, the set of assemblies comprising a waveguide slot antenna assembly comprising a set of numerous waveguide slot antennas, each set of waveguide slot antennas comprising an antenna feeding element forming a set of numerous antenna feeding elements, and a circuit device for transmitting and / or receiving radio frequency (RF) signals. The circuit device further comprises one or more circuit connection elements configured to form RF feeding connections with the antenna feeding elements of the numerous antenna feeding elements, the waveguide slot antenna assembly can be mounted on the circuit device in a number of different orientations, and a particular antenna feeding element of the set of numerous antenna feeding elements forms an RF feeding connection with each of the circuit connection elements in each orientation.
[0006] In one example, the number of waveguide slot antenna sets is equal to the number of different orientations, meaning that, for example, when mounting the assembly to a circuit device, it may be possible to utilize different exclusive orientations for each of a particular set of waveguide slot antennas from among many sets of waveguide slot antennas. The advantage of the presented feature is that a single waveguide slot antenna assembly can combine many different types of waveguide slot antenna sets with different characteristics for different use cases, and it may be possible to select the active (operating) set of waveguide slot antennas by changing the orientation in which the waveguide slot antenna set is mounted to the circuit device. This can reduce manufacturing costs because it is only necessary to manufacture one waveguide slot antenna assembly that can serve different purposes depending on the use case.
[0007] In another example, there may be a number of antenna feeding elements corresponding to the number of sets of waveguide slot antennas on the waveguide slot antenna assembly, but only one circuit connection element. In this example, the number of antenna feeding elements can also correspond to a number of different orientations, and each of these antenna feeding elements may be able to form an RF feeding connection with a single circuit connection element. This makes it possible to manufacture the circuit device easily and at a reduced cost, and this circuit device can later supply RF signals to a specific set of waveguide slot antennas from the set of multiple waveguide slot antennas via the same circuit connection element. The set of active waveguide slot antennas can be selected by changing the orientation in which the waveguide slot antenna assembly is mounted on the circuit device.
[0008] For example, when forming an RF feed connection with a single circuit connection element, a single antenna feed element can be combined with multiple RF connections to send and receive RF signals with, for example, each of a set of waveguide slot antennas.
[0009] In a different example, there may be a number of antenna feeding elements and a number of circuit connection elements, where the number of antenna feeding elements corresponds to the number of sets of waveguide slot antennas on the waveguide slot antenna assembly. The number of circuit connection elements may be equal to or less than the number of antenna feeding elements. In this example, one circuit connection element may correspond to and be connected to one or more antenna feeding elements. In this case, the set of active waveguide slot antennas can also be selected by changing the orientation in which the waveguide slot antenna assembly is mounted on the circuit device.
[0010] For example, the assembly set may further include a printed circuit board (PCB) containing circuitry, or a radio frequency IC (RFIC) containing circuitry, or a system-on-a-chip (SOC) containing circuitry. The advantage of providing a PCB, or either an RFIC or SOC containing circuitry, is that it is possible to provide a platform that facilitates mounting and securing the waveguide slot antenna assembly, and at the same time, an RF feeding platform including circuit connection elements for feeding the waveguide slot antenna assembly. Preferably, the PCB, or RFIC or SOC, can provide specific mounting mechanisms to achieve different exclusive orientations to which the waveguide slot antenna assembly can be mounted to the circuitry.
[0011] In an example of a set of assemblies including an RFIC, the RFIC can serve the purpose of enabling the circuit device to transmit and receive electromagnetic waves and / or radio frequencies. This allows for the combination of waveguide slot antenna assemblies and circuit devices to achieve a compact form factor, as the combined components may not depend on an integrated circuit outside the device.
[0012] In an example of a set of assemblies including a SOC, the SOC may also include, for example, units that transmit electromagnetic waves and / or radio frequencies via an integrated RFIC, and units that receive electromagnetic waves and / or radio frequencies, or composite units that transmit and receive electromagnetic waves and / or radio frequencies. In this example, the SOC may also be mounted directly to the set of assemblies without a PCB. The SOC may further include other interfaces, such as a digital signal processor (DSP) or an Ethernet / network interface. Preferably, these additional units may enable the set of assemblies to process, store, analyze, pre-process, or post-process radio frequency (RF) data or any type of data, but not limited to these. Providing a compact SOC may allow for miniaturization of the device, reduction of manufacturing costs through mass production, and mounting the same circuitry in various sets of waveguide slot antenna assemblies, because the manufactured hardware, in the case of an SOC, will be similar and can be mounted, powered, and supplied to different sets of waveguide slot antenna assemblies.
[0013] In one example, a waveguide slot antenna assembly is configured to indicate its orientation for mounting to a circuit device using contacts that are opened or closed depending on the mounting specific to a different orientation, and the circuit device is configured to control its operation according to the indicated mounting orientation. Preferably, this may allow the circuit device to determine the active set of waveguide slot antennas from a set of multiple slot antennas by relying on the information provided by the contacts. In this case, the determination of the active waveguide slot antenna elements may be required not only by the way the antenna feeding elements connect to the circuit connection elements, but also by the way one or more of the multiple contacts are opened or closed. Examples of contacts may be, but are not limited to, mechanical, optical, or electrical connections between the waveguide slot antenna assembly and the circuit device.
[0014] In another example, if there are many circuit connection elements, the circuit device is configured to control its operation by activating only the circuit connection elements indicated by the indicated mounting orientation that are currently forming an RF feed connection with the antenna feed element. In one example, it may not be necessary to supply an RF signal through many RF connection elements if only one may be in use. Energy can be saved by deactivating RF connection elements that may not be necessary for the current operation.
[0015] In one example, the circuit device is configured to control its operation by adapting the generation of RF signals and / or the analysis of received RF signals to suit a set of waveguide slot antennas currently connected to the circuit connection element and indicated by the mounting orientation. In one example, different sets of waveguide slot antennas in the waveguide slot antenna assembly may have different characteristics, including, but are not limited to, different wavelengths, different antenna gains, different antenna directivity, and different antenna patterns. In one example, the operation of the circuit device can be adapted to the characteristics of the currently active set of waveguide slot antennas so that, when transmitting a signal, the signal supplied to the antenna has the correct characteristics (e.g., frequency, modulation, power, etc.), and when receiving a signal, the signal received from the antenna is reliably and accurately amplified, filtered, and / or interpreted.
[0016] For example, adapting RF signal generation to suit a set of waveguide slot antennas involves utilizing at least one of the RF frequencies, power, antenna element spacing, and modulation inherent to the set of waveguide slot antennas. Different sets of waveguide slot antennas in a waveguide slot antenna assembly can be used for different purposes, such that different characteristics may be desirable for each set of antennas. Thus, each set of waveguide slot antennas can be defined by specific characteristics, such as RF transmission and reception wavelengths, so that it may be advantageous for supplying RF signals of a particular frequency range to the antennas. The advantage of such a design may be that a single waveguide slot antenna assembly can be used for different scenarios where different RF frequencies, power, and modulation are desirable for each scenario. In one example, assemblies of many configurations can be mounted in different locations within a vehicle, and a single set of waveguide slot antennas in an antenna assembly can be used in medium-to-long-range radar functions, including, but not limited to, front and corner radar for adaptive driving control. Sets of waveguide slot antennas with different configurations of antenna assemblies can be used in short-range applications, including, but are not limited to, blind spot detection, curb detection in parking assist, obstacle detection in door open warnings, and detection of pedestrians and cyclists. In these examples, different frequencies, powers, and modulation characteristics of RF signals can be advantageous, and it may be necessary to use a specific waveguide slot antenna for each of the particularly characterized signals. The RF receiving chain can be adapted accordingly. In another example, different or identical waveforms can be used for different sets of waveguide slot antennas, and the spacing between antenna elements may differ when comparing different sets of waveguide slot antennas. This allows for different sensor performance characteristics.
[0017] In one example, each set of waveguide slot antennas includes 1 to 8 waveguide slot antennas for receiving radio frequency signals and 1 to 8 waveguide slot antennas for transmitting radio frequency signals, preferably 3 to 5 waveguide slot antennas for receiving radio frequency signals and 3 to 5 waveguide slot antennas for transmitting radio frequency signals, most preferably 3 to 4 waveguide slot antennas for receiving radio frequency signals and 3 to 4 waveguide slot antennas for transmitting radio frequency signals. In one example, the set of waveguide slot antennas may include 4 transmitter (Tx) and 4 receiver (Rx) elements. In another minimal configuration, there may be one transmit / receive channel (TRx) with one transmit / receive antenna, and the antenna element can perform the functions of both a transmit and receive antenna.
[0018] Preferably, the waveguide slot antenna set further includes fixing means for securing the waveguide antenna assembly to a circuit device, the fixing means configured to exclusively allow fixing in a number of different orientations. The fixing means may include, but are not limited to, opposing couplings or joints, including clamping, welding, riveting, soldering, and / or screwing. At least one fixing point may be present on the waveguide slot antenna assembly, and at least one opposing fixing point may be present on the PCB and / or RFIC and / or SOC, each of which includes a circuit device.
[0019] In one example, the slots in a set of multiple waveguide slot antennas are contained within a common radiating surface. The advantage of this solution is that it can result in a compact form factor, as it may only require a single radiating surface. The antenna assembly may also be flatter and easier to integrate into the equipment.
[0020] Preferably, the radiating surface is a continuous surface. This allows for further reduction of manufacturing costs and increased manufacturing speed because only one piece of material needs to be machined to manufacture one waveguide slot antenna assembly, and a waveguide slot antenna assembly may contain a set of multiple waveguide slot antennas. In one example, the material can be metal, metallized plastic, or any kind of conductive material. In another example, instead of milling the slots, the waveguide slot antenna assembly can be manufactured with multiple layers to form the slots and holes. In yet another example, the common radiating surface can be 3D printed. Preferably, there may be an RF connection between the antenna feeding element and the circuit connection element, a layer of resonant cavities / coupled apertures which may be sandwiched transition layers, and a feeding network layer which may connect to a circuit device, RFIC, or SOC via a radiating layer where slots may exist.
[0021] In another embodiment, a method for mounting a set of radio frequency transceivers and receivers is described, the method comprising: providing a waveguide slot antenna assembly, the waveguide slot antenna assembly comprising a set of a plurality of waveguide slot antennas, each set of waveguide antennas comprising an antenna feeding element that forms a set of a plurality of antenna feeding elements; providing a circuit device for transmitting and receiving radio frequency (RF) signals, the circuit device further comprising one or more circuit connection elements configured to form an RF feeding connection with the antenna feeding elements of a plurality of antenna feeding elements; and mounting the waveguide slot antenna assembly to the circuit device in one of a plurality of different orientations, wherein a particular of the antenna feeding elements forms an RF feeding connection with each of the circuit connection elements in each orientation.
[0022] It is understood that one or more of the aforementioned examples can be combined, provided that they are not mutually exclusive.
Brief Description of the Drawings
[0023] Hereinafter, examples will be described in more detail with reference to the drawings. [Figure 1] It is a schematic view of a side view of a set of radio frequency transceiver assemblies. [Figure 2] It is a schematic front view of a waveguide slot antenna assembly. [Figure 3] It is a schematic back view of a waveguide slot antenna assembly. [Figure 4] It is a schematic view of a side view of a set of radio frequency transceiver assemblies. [Figure 5] It is a schematic view of a side view of a set of radio frequency transceiver assemblies. [Figure 6] It is a schematic view of a side view of a set of radio frequency transceiver assemblies.
Modes for Carrying Out the Invention
[0024] Hereinafter, similar elements are denoted by the same reference numerals.
[0025] FIG. 1 shows a schematic side view of a set of radio frequency transceiver assemblies, the set of assemblies including a waveguide slot antenna assembly 100 having a set of waveguide slot antennas each including a set of waveguide antennas. Each set includes a number of antennas formed, for example, by one or more slots 102, 104 respectively. The waveguide slot antenna assembly 100 includes a number of antenna feeding elements 106 and is attached to a PCB 108. One of the antenna feeding elements 106 is coupled to a circuit connection element 110 which is part of the PCB 108. The PCB 108 further includes circuitry 112 on the opposite side of the PCB 108, opposite to the waveguide slot antenna assembly. [[ID=*37]]
[0026] In this example, it is assumed that the waveguide slot antenna assembly includes a set of two waveguide slot antennas, each having slots 102 and 104. Here, the waveguide slot antenna assembly 100 can be mounted on PCB 108 in two exclusive orientations. For example, the exclusive orientations can be selected by rotating the waveguide slot antenna assembly 100 by 90° in the horizontal plane of Figure 1. In this example, the horizontal plane is defined as follows: the circuit device 112 is mounted on the bottom surface of PCB 108, and the waveguide slot antenna assembly 100 is mounted on the top surface of PCB 108. The plane is defined by PCB 108, and rotating the waveguide slot antenna assembly 100 by 90° in the horizontal plane means that the axis of rotation is perpendicular to the plane defined by the PCB.
[0027] Depending on which exclusive orientation is selected when mounting the waveguide slot antenna assembly 100 to the PCB 108, one of the two antenna feeding elements 106 can be connected to the circuit device 112 by forming an RF connection with the circuit connection element 110. Each antenna feeding element and circuit connection element can have multiple RF channels for transmitting RF signals between the waveguide antenna and the circuit device 112. In the example shown in Figure 1, the antenna feeding element 106 is coupled to a set of waveguide antennas including a slot 102. For example, by mounting the waveguide slot antenna assembly 100 to the PCB in one of several exclusive orientations, the other of the two antenna feeding elements having a slot 104 forms an RF feeding connection with the circuit connection element 110. Therefore, one set of assemblies can be used with multiple sets of waveguide antennas, and depending on the orientation in which the waveguide antenna assembly 100 is mounted to the PCB 108, a specific set of waveguide antennas having slots 102 or 104 can be used.
[0028] Figure 2 shows a schematic diagram of a waveguide slot antenna assembly 100. In this example, the waveguide slot antenna assembly 100 includes two sets of waveguide slot antennas, each set containing, for example, a number of antennas, each antenna being formed by, for example, one or more slots. Slots 102 and 104 correspond to the different sets of the two waveguide antennas, respectively. Furthermore, Figure 2 shows eight slots for one set of waveguide slot antennas, four of the eight slots functioning as receiving (RX) antenna channels and the other four of the eight slots functioning as transmitting (TX) antenna channels. In this example, each of the four receiving channels and four transmitting channels for one set of waveguide slot antennas is paired, forming an array of four slots for each receive / transmit pair. The slots in each channel can have different widths and lengths, which determines the various characteristics of each set of antennas (i.e., specific RF frequencies, power, and modulation for each waveguide slot antenna).
[0029] The waveguide slot antenna assembly 100 in Figure 2 further includes two antenna feeding elements 106 and 202, which are located, for example, on the back side of the waveguide slot antenna assembly. Therefore, the antenna feeding elements are not on the front side of the waveguide slot antenna assembly presented in Figure 2, and are shown for illustrative purposes only. In the example in Figure 2, antenna feeding element 106 is currently in use and therefore an active antenna feeding element, and is assumed to form an RF feeding connection with a circuit connection element not visible in the figure. In this example, the other antenna feeding element 202 is not currently forming an RF feeding connection with a circuit connection element and is not operating. Antenna feeding element 106 supplies and receives RF signals to and from a set of waveguide slot antennas having, for example, waveguide antenna slot 102. Antenna feeding element 202, when active, supplies and receives RF signals to and from a set of waveguide slot antennas having waveguide antenna slot 104. In this example, the waveguide antenna slot 102 of each set of waveguide slot antennas, as well as its four transmit channels and four receive channels, are currently active.
[0030] The waveguide slot antenna assembly 100 in Figure 2 further includes two sets of holes, 204, 206, for fixing means, for example, using screws. In this example, one set of holes 204 corresponds to one of two possible exclusive orientations, and the other set of holes 206 corresponds to the other possible exclusive orientation, which can be selected by rotating the waveguide slot antenna assembly 100 by 90° in the plane of Figure 2.
[0031] In this example in Figure 2, waveguide antenna slot 102 is the set of active waveguide slot antennas, 106 is the antenna feeding element currently in use, and hole 204 is used to secure the waveguide slot antenna assembly to the PCB, RFIC, or SOC, and allows mounting in one of two possible exclusive orientations of the waveguide slot antenna assembly. The waveguide slot antenna assembly can be mounted (and secured via hole 206) rotated 90° to the right, so that the antenna feeding element 202 establishes an RF connection with the circuit connection element. In this case, hole 206 is aligned with the corresponding hole in the PCB, RFIC, or SOC, allowing the waveguide slot antenna assembly to be secured in the other exclusive orientation of the two possible orientations. As a result, waveguide antenna slot 104 of the other set of two waveguide slot antennas becomes active to transmit and receive radio frequencies.
[0032] In the waveguide slot antenna assembly 100 shown in Figure 2, the waveguide antenna slot 104 is larger and longer, while the waveguide antenna slot 102 is shorter and more compact overall. Antenna elements with larger waveguide antenna slots 104 have a more directional radiation pattern and can radiate more power in the desired direction. Therefore, a set of waveguide slot antennas with waveguide antenna slots 104 can be used in vehicles as forward and corner radar for medium-to-long-range radar functions, for example, for adaptive cruise control (ACC) or parking assist purposes. A set of waveguide slot antennas with waveguide antenna slots 102 can be used for short-range applications, such as blind spot detection, curb detection in parking assist, obstacle detection in door open warnings, pedestrian detection, and detection of cyclists.
[0033] Figure 3 shows a schematic view of the back of a waveguide slot antenna assembly 100, for example, the one described above in Figure 2. In this example, the antenna feeding elements 106 and 202 are located on the back of the device shown in the figure. The back also includes, for example, holes 204 and 206, which allow the waveguide slot antenna assembly to be mounted to a circuit device in one of two possible mutually exclusive orientations.
[0034] Figure 4 shows another schematic side view of the waveguide slot antenna assembly 100 mounted on PCB 108. In this example, the features of this schematic are similar to those in Figure 1, except that in this example the circuit device 112 is on the same side of PCB 108 as the waveguide slot antenna assembly 100 and is adjacent to the RF feed connection formed by the antenna feed element 106 and the circuit connection element 110.
[0035] Figure 5 shows another schematic side view of the waveguide slot antenna assembly 100 mounted on PCB 108. In this example, the circuit assembly 112 is on the opposite side of PCB 108 compared to Figure 1. However, in this example, the circuit connection element 110 is directly contained within the circuit assembly 112, and the antenna feeding element 106 penetrates and traverses PCB 108 to form an RF feeding connection.
[0036] Figure 6 shows another schematic side view of the waveguide slot antenna assembly 100 mounted on PCB 108. In this example, the waveguide slot antenna assembly 100 is directly mounted on circuitry 112, which is further mounted on PCB 108. In addition, circuitry 112 includes two circuit connection elements 106, 202, and the waveguide slot antenna assembly 100 includes two antenna feeding elements 106, 202. Figure 6 further includes a contact 604, where the current state (e.g., open, closed) indicates, for example, that the waveguide slot antenna assembly 100 is mounted in the first exclusive orientation of two possible exclusive orientations when the contact 604 is open, and that the waveguide slot antenna assembly 100 is mounted in the second exclusive orientation of two possible exclusive orientations when the contact 604 is closed.
[0037] In the first exclusive orientation, the antenna feeding element 106 is coupled to the circuit connection element 110, and in the second exclusive orientation, the antenna feeding element 202 is coupled to the circuit connection element 602.
[0038] For example, in Figure 6, the contact is open, which indicates that the waveguide slot antenna assembly 100 is mounted in a first exclusive orientation, and thus the antenna feeding element 106 and each of the circuit connection elements 110 are determined to be active elements forming an RF feeding connection. In this example, there is currently no active RF feeding connection between the antenna feeding element 202 and the circuit connection element 602. For example, if the waveguide slot antenna assembly 100 is mounted in a second exclusive orientation, the contact 604 will be closed, and an RF feeding connection will exist between the antenna feeding element 202 and the circuit connection element 602. In this example, when the contact 604 is closed, there is no RF feeding connection between the antenna feeding element 106 and the circuit connection element 110.
[0039] Contact 604 can also be used in conjunction with the examples in Figures 1 to 5, in which case only one circuit connection element 602 is used. In this case, the state of contact 604 can indicate the currently used orientation of assembly 100, that is, it can indicate which antenna feeding element, and by extension, which set of waveguide antennas, is in use and coupled to the circuit device 112.
