Description

Technical Field

[0001] This application relates to the field of satellite antenna locking technology, specifically to a petal-shaped locking mechanism. Background Technology

[0002] The antenna size of mobile terminals used in the current Internet of Things (IoT) industry depends on the frequency band and wavelength. Especially for longer antennas, external antennas are typically used, which presents a series of challenges in practical applications. External antennas result in a larger overall antenna envelope, and their structural stability is weak, making them susceptible to physical damage during use. Fixed antenna size and installation methods limit the application range of the device, making its use inflexible. Space constraints and fixed antenna thickness and length prevent it from flexibly adapting to the needs of special frequency bands such as 240MHz and 320MHz. Utility Model Content

[0003] In view of this, the main objective of this application is to provide a petal-shaped locking mechanism, which helps to solve the problems of large overall envelope, unstable antenna installation structure, and inability to flexibly adapt to different frequency bands caused by the external antenna of existing Internet of Things mobile terminals.

[0004] This application provides a petal-shaped locking mechanism, which includes:

[0005] The petal-shaped base is hollow inside, and a retaining ring is provided around the outer perimeter of the petal-shaped base.

[0006] The petal drive plate is located in the inner cavity of the petal support base;

[0007] The lower chuck is sleeved on the outside of the petal holder base and is supported by a retaining ring. A first annular toothed rack is provided at the upper end of the lower chuck.

[0008] The upper chuck has an antenna mounted around its outer edge, and a second annular rack is provided at the lower end of the upper chuck, which engages with the first annular rack.

[0009] A compression spring is located at the upper end of the upper chuck;

[0010] A pressing flange is located above the compression spring;

[0011] The release button runs through the middle of the pressing flange, the clamping spring, the upper chuck, and the lower chuck, and contacts the bottom end of the petal drive plate.

[0012] As shown above, the antenna wraps around the outer edge of the upper chuck. This built-in antenna design reduces the overall envelope of the petal-shaped locking mechanism. The petal drive plate has an elastic function; when the release button is pressed down, the petal drive plate pushes the upper chuck upward, allowing the upper chuck to rotate as the antenna is pulled outward. After the antenna is pulled out a certain length, the portion of the antenna surrounding the edge of the upper chuck is pulled out in a spiral shape. When the release button is released, the petal drive plate returns to its original shape. Under the action of the compression spring, the pressing flange, and the gravity of the upper chuck itself, the upper chuck descends, and the upper chuck... The second annular rack of the upper chuck makes gap contact with the first annular rack of the lower chuck, causing the upper chuck to be locked in place by the lower chuck and unable to rotate. When the antenna is retracted, pressing the release button will cause the petal drive plate to push the upper chuck upward. After the antenna rebounds and causes the upper chuck to rotate, releasing the release button will lock the upper chuck in place. The change in length and shape of the antenna after it is pulled out allows the petal-shaped locking mechanism to flexibly adapt to antennas of different frequency bands. The clamping spring and the pressing flange press against the upper end of the upper chuck, making the upper chuck more stable when fixed, thus making the antenna installation method more stable.

[0013] Optionally, the petal drive plate includes: a base with a locking hole at its center; and multiple petal-shaped components arranged around the base.

[0014] As shown above, the base can withstand the downward pressure from the release button. After the base withstands the downward pressure, multiple petal-shaped components can extend upward. These multiple petal-shaped components are evenly arranged around the base, so that when the multiple petal-shaped components lift the upper chuck upward, the lifting force on the upper chuck is uniform, and the upper chuck rises smoothly without tilting.

[0015] Optionally, the petal-shaped component is arc-shaped, with its lower end abutting against the bottom end of the petal-shaped base and its upper end abutting against the inner wall of the petal-shaped base.

[0016] As shown above, the petal-shaped component is arc-shaped as a whole. The inner cavity of the petal support base restricts the extension of the petal-shaped component, limiting the outward expansion of the petal-shaped component as a whole, thereby allowing the petal-shaped component to extend upward, thus enabling the petal drive plate to push upward.

[0017] Optionally, the base plate of the petal holder base has a base through hole at its center, and the base through hole and the locking hole are located on the same central axis.

[0018] As shown above, the through hole in the center of the petal-shaped base is used to connect the antenna to the PCB circuit board, thereby enabling the antenna to transmit and receive functions.

[0019] Optionally, the bottom of the release button abuts against the locking hole in the center of the base.

[0020] From above, the bottom of the release button abuts against the locking hole in the center of the base, making the base bear the downward pressure of the release button more evenly.

[0021] Optionally, the antenna includes a ring portion, an inwardly fixed portion, and an outwardly extending portion.

[0022] As described above, the antenna is designed with a circular ring, an inward fixing part, and an outward extending part. The connection between the inward fixing part and the circular ring is set at 90°, and the outward extending part is tangent to the circular ring. The circular ring, the inward fixing part, and the outward extending part are integrated, allowing the antenna to be installed in a built-in manner.

[0023] Optionally, an annular groove is provided on the outer edge of the upper chuck, with the annular portion surrounding the annular groove.

[0024] As shown above, the circular part of the antenna surrounds the annular groove of the upper chuck. This installation method can reduce the overall envelope of the petal-shaped locking mechanism and make it easy to use.

[0025] Optionally, a chuck hole is provided in the annular groove, and the inward fixing part is connected to the chuck hole.

[0026] From the above, the chuck's circular hole extends from the outside of the annular groove to the center through hole of the upper chuck and passes through it. The antenna's inner fixing part is fixed at the chuck's circular hole, and the inner fixing part extends into the center through hole of the upper chuck. One end of the inner fixing part is connected to the PCB circuit board through a wiring. The wiring enters the interior of the petal-shaped locking mechanism through the base through hole of the petal support base.

[0027] Optionally, the diameter of the center through hole of the lower chuck is larger than the diameter of the center through hole of the upper chuck.

[0028] From top to bottom, the lower chuck is fitted onto the outside of the petal-shaped base. When the upper chuck contacts the lower chuck, the upper chuck is positioned precisely at the top of the petal-shaped base. The central through-hole of the upper chuck accommodates the release button. Therefore, the diameter of the central through-hole of the upper chuck should be smaller than the diameter of the central through-hole of the lower chuck; this structure is more reasonable. Optionally, an inclined portion is provided around the bottom of the release button, and the inclined portion abuts against the locking hole.

[0029] As shown above, the inclined part around the bottom of the release button is tightly pressed against the inside of the locking hole, making the base bear the force more evenly.

[0030] In summary, the petal-shaped locking mechanism provided in this application features a hollow design inside the petal support base, providing installation space for the petal support drive plate. A retaining ring on the outer side of the petal support base supports the lower chuck and provides physical restraint to prevent the lower chuck from sliding out or shifting. The upper and lower chucks are interlocked by a ring-shaped rack, ensuring a tight connection and improving the overall torsional resistance of the structure through rack meshing, thus enhancing the stability of the upper chuck installation. The antenna is mounted around the outer edge of the upper chuck, facilitating integration and adjustment to reduce the envelope of the petal-shaped locking mechanism and adapt to antennas of various frequency bands. A compression spring and a pressing spring are also included. A constant pressure is applied to the flange to keep the petal drive plate in a proper working state, ensuring a more stable locking structure for the upper chuck, which in turn makes the antenna installation more secure. The inclined part around the bottom of the release button is tightly pressed against the locking hole in the center of the base at the bottom of the petal drive plate. When the release button is pressed down, the petal drive plate springs up, thus lifting the upper chuck to unlock the antenna. When the release button is released, the petal drive plate immediately returns to its original shape. Under the action of the compression spring, the pressing flange, and the gravity of the upper chuck itself, the upper chuck falls down and engages with the lower chuck, thereby locking the antenna.

[0049] The technical solutions of this application and how they solve the aforementioned technical problems will be described in detail below with specific embodiments.

The same or similar ideas or processes described in one embodiment may not be repeated in other embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0050] This application provides a petal-shaped locking mechanism, which includes:

[0051] The petal support base 1 is hollow inside, and a retaining ring 101 is provided around the outer perimeter of the petal support base 1.

[0052] The petal drive plate 2 is located in the inner cavity of the petal support base 1;

[0053] The lower chuck 3 is sleeved on the outside of the petal support base 1, and the lower chuck 3 is supported by the retaining ring 101. The upper end of the lower chuck 3 is provided with a first annular toothed rack 301.

[0054] The upper chuck 4 has an antenna 8 mounted around its outer edge. The lower end of the upper chuck 4 is provided with a second annular rack 401, which engages with the first annular rack 301.

[0055] A compression spring 5 is installed at the upper end of the upper chuck 4;

[0056] Press flange 6 is positioned above compression spring 5;

[0057] Release button 7 is located in the middle of pressing flange 6, clamping spring 5, upper chuck 4 and lower chuck 3, and contacts the bottom end of petal drive plate 2.

[0058] Specifically, the antenna 8 is wrapped around the outer edge of the upper chuck 4. This built-in antenna 8 reduces the overall envelope of the petal-shaped locking mechanism. The petal drive plate 2 has an elastic function. When the release button 7 is pressed down, the petal drive plate 2 pushes the upper chuck 4 upward, allowing the upper chuck 4 to rotate as the antenna 8 is pulled outward. After the antenna 8 is pulled out a certain length, the portion of the antenna 8 surrounding the edge of the upper chuck 4 is pulled out in a spiral shape. When the release button is released, the petal drive plate 2 returns to its original shape. Under the action of the compression spring 5, the pressing flange 6, and the gravity of the upper chuck 4, the upper chuck 4 descends. The second annular rack 401 makes gap contact with the first annular rack 301 of the lower chuck 3, so that the upper chuck 4 is locked by the lower chuck 3 and cannot rotate. When the antenna 8 is retracted, the release button 7 is pressed, and the petal drive plate 2 will push the upper chuck 4 upward. After the antenna 8 rebounds and drives the upper chuck 4 to rotate, the release button 7 is released to fix the upper chuck 4. The change in length and shape of the antenna 8 after it is pulled out makes the petal-shaped locking mechanism flexibly adaptable to antennas 8 of different frequency bands. The compression spring 5 and the pressing flange 6 press on the upper end of the upper chuck 4, making the upper chuck 4 more stable when fixed, thus making the fixed installation of the antenna 8 more stable.

[0059] Optionally, the diameter of the central through hole of the lower chuck 3 is larger than the diameter of the central through hole of the upper chuck 4.

[0060] Specifically, the lower chuck 3 is sleeved on the outside of the petal holder base 1. When the upper chuck 4 contacts the lower chuck 3, the upper chuck 4 is located at the top of the petal holder base 1. The central through hole of the upper chuck 4 accommodates the release button 7. Therefore, the diameter of the central through hole of the upper chuck 4 should be smaller than the diameter of the central through hole of the lower chuck 3. This structure is more reasonable.

[0061] like Figure 1-2 As shown, the petal support base 1 is hollow inside, and a petal drive plate 2 is installed inside the petal support base 1. A lower chuck 3 is sleeved on the outside of the petal support base 1, and the petal support base 1 holds the lower chuck 3 to prevent it from rotating. A first annular rack 301 is provided at the upper end of the lower chuck 3, and a second annular rack 401 is provided at the lower end of the upper chuck 4. The first annular rack 301 at the upper end of the lower chuck 3 and the second annular rack 401 at the lower end of the upper chuck 4 are in clearance contact, so that the lower chuck 3 can tightly hold the upper chuck 4 to prevent the upper chuck 4 from rotating. An antenna 8 is surrounded around the upper chuck 4, and a compression spring 5 is placed at the upper end of the upper chuck 4 (e.g., an antenna 8). Figure 9As shown), a pressing flange 6 is placed on the upper end of the compression spring 5. The antenna 8 can be fixed via the connection structure between the petal support base 1, lower chuck 3, upper chuck 4, compression spring 5, and pressing flange 6. The bottom end of the release button 7 passes sequentially through the middle through hole of the pressing flange 6, the middle of the compression spring 5, the middle through hole of the upper chuck 4, and the middle through hole of the lower chuck 3, until it abuts against the middle pressing hole of the petal drive plate 2 inside the petal support base 1. (Refer to...) Figure 2 When the release button 7 is pressed down manually, the bottom of the release button 7 presses down on the petal drive plate 2. The petal-shaped component 202 of the petal drive plate 2 will extend upward, thereby lifting the upper chuck 4. This causes the second annular rack 401 at the lower end of the upper chuck 4 to separate from the first annular rack 301 at the upper end of the lower chuck 3. As a result, the antenna 8 surrounding the upper chuck 4 can rotate with the upper chuck 4 to unlock the antenna 8.

[0062] Optionally, the petal drive piece 2 includes: a base 201 with a locking hole at its center; and multiple petal-shaped components 202 arranged around the base 201.

[0063] Specifically, the base 201 can withstand the downward pressure from the release button 7. After the base 201 withstands the downward pressure, multiple petal-shaped components 202 can extend upward. The multiple petal-shaped components 202 are evenly arranged around the base 201, so that when the multiple petal-shaped components 202 push the upper chuck 4 upward, the lifting force on the upper chuck 4 is uniform, and the upper chuck 4 rises smoothly without tilting.

[0064] Optionally, the petal-shaped component 202 is arc-shaped, with its lower end abutting against the bottom end of the petal-shaped base 1 and its upper end abutting against the inner wall of the petal-shaped base 1.

[0065] Specifically, the petal-shaped component 202 is arc-shaped in general. The inner cavity of the petal support base 1 restricts the extension of the petal-shaped component 202, which restricts the overall outward expansion of the petal-shaped component 202, thereby allowing the petal-shaped component 202 to extend upward, thus enabling the petal drive plate 2 to push upward.

[0066] Optionally, the base plate of the petal holder 1 has a base through hole at its center, and the base through hole and the locking hole are located on the same central axis.

[0067] Specifically, the base through hole set at the center of the petal support base 1 is used to connect the antenna 8 to the PCB circuit board, thereby enabling the antenna 8 to transmit and receive functions.

[0068] like Figure 3As shown, the petal holder base 1 is hollow inside, and the interior of the hollow petal holder base 1 is referred to as the inner cavity. The inner cavity is cylindrical, and a base through hole is provided in the middle of the bottom end of the inner cavity (see reference). Figure 2 (As shown in the cross-sectional view), the through hole of the base allows the petal holder base 1 to be fixed on other equipment. A retaining ring 101 is provided around the outer wall of the petal holder base 1. The retaining ring 101 is provided to support and hold the lower chuck 3.

[0069] like Figure 4 As shown, the petal-shaped drive plate 2 is generally petal-shaped. The petal-shaped drive plate 2 includes a base 201 and petal-shaped components 202. The base 201 is disc-shaped with a locking hole in the center. Six petal-shaped components 202 are arranged obliquely downwards around the base 201, evenly surrounding the base 201. Each petal-shaped component 202 is arc-shaped, and the side of each component is approximately hook-shaped. 02 extends obliquely downward from the base 201, contacts the bottom of the inner cavity, and then extends upward to abut against the upper end of the inner cavity sidewall. The upper end of the petal-shaped component 202 has an arc-shaped curved structure. When the base 201 is subjected to a downward force, it will press the petal-shaped component 202 to move upward along the inner cavity sidewall. The curved structure at the upper end of the petal-shaped component 202 will lift the upper chuck 4. The curved structure at the upper end of the petal-shaped component 202 is smooth and will not wear the upper chuck 4, and it also facilitates the rotation of the upper chuck 4.

[0070] The number of petal-shaped components 202 can be set not only to six, but also to seven, eight or nine, or even more or fewer. However, the setting of the number of petal-shaped components 202 should ensure that the upper chuck is subjected to uniform force when moving up and down, and that the upper chuck does not tilt during the entire movement.

[0071] It should be noted that the petal-driven piece 2 in this application is made of an elastic alloy, which is a type of precision alloy mainly used to manufacture elastic sensitive elements, energy storage elements, and frequency elements in precision instruments. In addition to having good elastic properties, it also has properties such as non-magnetic, high resistance to micro-plastic deformation, high hardness, low resistivity, small temperature coefficient of elastic modulus, and low internal friction.

[0072] Optionally, the bottom of the release button 7 abuts against the locking hole in the center of the base 201.

[0073] Specifically, the bottom of the release button 7 abuts against the locking hole in the center of the base 201, so that the base 201 bears the downward pressure of the release button 7 more evenly.

[0074] Optionally, the bottom periphery of the release button 7 is provided with an inclined portion, which abuts against the locking hole.

[0075] Specifically, the inclined portion around the bottom of the release button 7 is tightly pressed against the inside of the locking hole, making the base 201 bear the force more evenly.

[0076] like Figure 5 As shown, the overall cross-section of the release button 7 is T-shaped. The diameter of the upper cylinder of the release button 7 is larger than the diameter of the lower cylinder, and the height of the upper cylinder of the release button 7 is much smaller than the height of the lower cylinder. The top of the upper cylinder of the release button 7 is provided with a raised circular structure, which can provide the staff with a more comfortable pressing experience. The bottom of the release button 7 is provided with an inclined part, or it can be said that the lower end of the release button 7 uses a chamfering process, and the inclined part is tightly abutted against the locking hole in the middle of the petal drive plate 2.

[0077] Optionally, the antenna 8 includes a ring portion 801, an inwardly fixed portion 802, and an outwardly extending portion 803.

[0078] Specifically, the antenna 8 is designed as a circular ring 801, an inward fixing part 802, and an outward protruding part 803. The connection between the inward fixing part 802 and the circular ring 801 is set at 90°. The outward protruding part 803 is tangent to the circular ring 801. The circular ring 801, the inward fixing part 802, and the outward protruding part 803 are integrated, so that the antenna 8 can be installed in a built-in manner.

[0079] In this embodiment, the material of the metal wire used in antenna 8 can be changed according to the actual antenna performance requirements. Antenna 8 has a resilient property and can be made of an elastic alloy metal. In this embodiment, the elasticity of antenna 8 is within its tolerable elastic deformation range to prevent antenna 8 from exceeding its elastic deformation range when stretched, thus causing antenna 8 to lose its resilience. The overall length of antenna 8 remains unchanged, and its overall length includes the length of the annular portion 801, the length of the inward fixing portion 802, and the length of the outward protruding portion 803.

[0080] Optionally, an annular groove is provided on the outer edge of the upper chuck 4, and the annular portion 801 surrounds the annular groove.

[0081] Specifically, the annular portion 801 of the antenna 8 surrounds the annular groove of the upper chuck 4. This installation method makes the overall envelope of the petal-shaped locking mechanism smaller and easier to use.

[0082] Optionally, a chuck hole 402 is provided in the annular groove, and the inward fixing part 802 is connected to the chuck hole 402.

[0083] Specifically, the chuck circular hole 402 extends from the outside of the annular groove to the center through hole of the upper chuck 4 and passes through it. The inner fixing part 802 of the antenna 8 is fixed at the chuck circular hole 402, and the inner fixing part 802 extends into the center through hole of the upper chuck 4 and is connected to the PCB circuit board through a wire. The wire enters the interior of the petal-shaped locking mechanism through the base through hole of the petal support base 1.

[0084] like Figure 6-7 As shown, a first annular rack 301 is arranged around the central through hole of the lower chuck 3, and four evenly distributed through holes are arranged on the outer side of the first annular rack 301; the pressing flange 6 has a disc-shaped structure, a flange through hole is arranged in the middle of the pressing flange 6, and four through holes are evenly arranged around the flange through hole; the release button 7 is set downward through the flange through hole of the pressing flange 6 and the central through hole of the lower chuck 3; the four through holes on the lower chuck 3 are used to fix it to other components, and the four through holes on the pressing flange 6 are also used to fix it to different components.

[0085] like Figure 8 As shown, a second annular toothed rack 401 is provided around the edge of the upper chuck 4, an annular groove is provided on the outer side of the edge of the upper chuck 4, and a chuck circular hole 402 is provided on the annular groove on the outer side of the edge of the upper chuck 4. The chuck circular hole 402 penetrates the radius of the upper chuck 4 until it reaches the central through hole of the upper chuck 4.

[0086] It should be noted that the toothed plates of the first annular rack 301 and the second annular rack 401 should be seamlessly connected when there is a clearance fit. Figure 1 This is only a schematic diagram of the petal-shaped locking mechanism. The inclined structure of the teeth on the two annular racks is to make it easier to position them when they are engaged.

[0087] like Figure 10As shown, the overall length of the antenna 8 in this embodiment is set to 200mm. The antenna 8 consists of three parts: a circular ring 801, an inward fixing part 802, and an outward extending part 803. The circular ring 801 is an open ring. The inward fixing part 802 is provided at one end of the ring opening, and the outward extending part 803 is provided at one end of the ring opening. The circular ring 801 surrounds the outer edge of the upper chuck 4, that is, the circular ring 801 is fitted into the annular groove. The inward fixing part 802 is inserted into the chuck hole 402 of the upper chuck 4 and fixed in place. Part 802 can be soldered to the chuck's circular hole 402 via a solder pad. The inner fixing part 802 extends into the center through hole of the upper chuck 4 and is connected to the PCB circuit board via a trace. The outer extension part 803 is used to transmit or receive signals. The outer extension part 803 can be stretched outward to adapt to different frequency bands. When the outer extension part 803 is pulled outward, the annular part 801 of the antenna 8 surrounding the annular groove of the upper chuck 4 extends outward with the rotation of the upper chuck 4, thereby making the length of the outer extension part 803 longer and the length of the annular part 801 shorter.

[0088] The petal-shaped locking mechanism is housed in the housing, which is made of engineering plastic to ensure stability while isolating signal interference. The housing includes a top and a bottom that interlock with each other. Four through holes evenly arranged around the central flange through hole on the pressing flange 6 are fixed to the top of the housing by bolts or screws. Four through holes arranged around the outer side of the first annular rack 301 on the lower chuck are fixed to the bottom of the housing or the circuit board built into the bottom of the housing by bolts or screws. The release button 7 protrudes from the top of the housing, and the outward extension 803 of the antenna 8 protrudes from the housing through the outlet on the side of the housing.

[0089] When the release button 7 is pressed, the petal drive plate 2 will immediately spring upward to lift the upper chuck 4, causing the second annular rack 401 of the upper chuck 4 to disengage from the first annular rack 301 of the lower chuck 3. At this time, the outward extension part 803 is manually pulled outward, and the upper chuck 4 rotates as the antenna 8 extends. After receiving the outward pulling force, the outward extension part 803 pulls the ring part 801 to extend out of the outer shell. After being stretched, the ring part 801 forms a spiral shape that spirals upward. Depending on the degree to which the antenna 8 is pulled out, the deformation and curvature of the ring part 801 are also different. The difference in the length and shape of the extended part of the ring part 801 and the length of the outward extension part 803 allows it to adapt to different frequency bands.

[0090] When it is necessary to lock the extension length of the antenna 8, release the release button 7, and the petal drive plate 2 will immediately return to its original state. Under the action of its own weight, the compression spring 5, and the pressing flange 6, the upper chuck 4 falls down, and the second annular rack 401 of the upper chuck 4 engages with the first annular rack 301 of the lower chuck 3, locking the upper chuck 4, thereby locking the extension length of the antenna 8.

[0091] When it is necessary to reduce the extension length of antenna 8, press the release button 7, and the petal drive plate 2 will immediately push the upper chuck 4 upward. The rebound force of antenna 8 will drive the upper chuck 4 to rotate, and antenna 8 will return to its original state when it is surrounded by the annular groove of the upper chuck 4.

[0092] In summary, the petal-shaped locking mechanism provided in this application features a hollow design inside the petal support base 1, providing installation space for the petal support drive plate. A retaining ring 101 on the outer side of the petal support base 1 supports the lower chuck 3 and provides physical restraint to prevent the lower chuck 3 from sliding out or shifting. The upper chuck 4 and lower chuck 3 are interlocked by an annular rack, ensuring a tight connection and improving the torsional resistance of the entire structure through rack meshing, thus enhancing the stability of the upper chuck 4 installation. The antenna 8 is mounted around the outer edge of the upper chuck 4, facilitating integration and adjustment to reduce the envelope of the petal-shaped locking mechanism and adapt to various frequency bands. The compression spring 5 and pressing flange 6 apply a constant pressure. The pressure keeps the petal drive piece 2 in a proper working state, ensuring that the locking structure of the upper chuck 4 is more stable, thereby making the installation of the antenna 8 more stable. The inclined part around the bottom of the release button 7 tightly abuts against the locking hole in the center of the base 201 at the bottom of the petal drive piece 2, so that the petal drive piece 2 can effectively spring up when pressed by the release button 7, thereby enabling the petal drive piece 2 to lift the upper chuck 4 to unlock the antenna. When the release button 7 is released, the petal drive piece 2 immediately returns to its original state. Under the action of the compression spring 5, the pressing flange 6 and the gravity of the upper chuck 4, the upper chuck 4 falls down and engages with the lower chuck 3, thereby locking the antenna 8.
