[0039] [First Embodiment]

[0040] See Figure 1 As shown, this embodiment provides a multifunctional antenna structure 100. Figure 1 As shown, the multi-functional antenna structure 100 includes a substrate B, a broadband antenna 1, a first frequency divider 2 electrically coupled to the broadband antenna 1, a second frequency divider 3 electrically coupled to the first frequency divider 2, an integration unit 4, a wireless network module 5 electrically coupled to the integration unit 4, and an LTE module 6 electrically coupled to the second frequency divider 3. The structure of each component of the multi-functional antenna structure 100 will be described below, and the connection relationships between the components of the multi-functional antenna structure 100 will be explained as appropriate.

[0041] In this embodiment, the broadband antenna 1 is disposed on the substrate B, and the broadband antenna 1 can be used to receive an antenna signal S1. The frequency (range) of the antenna signal S1 is between 615MHz and 7125MHz, but the present invention is not limited thereto.

[0042] The first frequency divider 2 is disposed on the substrate B, and the first frequency divider 2 can receive the antenna signal S1 and output a first primary frequency divider signal A1 and a second primary frequency divider signal A2 with different frequency ranges. The first frequency divider 2 generates the first primary frequency divider signal A1 through high-pass filtering, and generates the second primary frequency divider signal A2 through low-pass filtering. Preferably, the maximum frequency of the first primary frequency divider signal A1 is less than the minimum frequency of the second primary frequency divider signal A2 and has a first minimum difference value, and the first minimum difference value is preferably not less than 500MHz, but the present invention is not limited thereto. For example, the first minimum difference value can be adjusted as needed.

[0043] In this embodiment, after receiving the antenna signal S1, the first frequency divider 2 will output the antenna signal S1 as a first primary frequency divider signal A1 of 1805MHz to 4200MHz and a second primary frequency divider signal A2 of 5150MHz to 7125MHz respectively.

[0044] Re-reference Figure 1 As shown, the second frequency divider 3 is disposed on the substrate B, and the second frequency divider 3 can receive the first primary frequency divider signal A1 and output multiple secondary frequency divider signals with different frequency ranges, and any two secondary frequency divider signals with similar ranges have a second minimum difference of not less than 2MHz. Preferably, the second minimum difference can also be between 2MHz and 610MHz.

[0045] In a practical application, the number of the plurality of secondary frequency division signals is limited to four, and they are sequentially arranged according to frequency range as a first-level frequency division signal B1, a second-level frequency division signal B2, a third-level frequency division signal B3, and a fourth-level frequency division signal B4. Preferably, the frequency of the first-level frequency division signal B1 is between 1805MHz and 2400MHz, the frequency of the second-level frequency division signal B2 is between 2402MHz and 2482MHz, the frequency of the third-level frequency division signal B3 is between 2500MHz and 2690MHz, and the frequency of the fourth-level frequency division signal B4 is between 3300MHz and 4200MHz, but the present invention is not limited thereto.

[0046] The integration unit 4 is disposed on the substrate B, and in this embodiment, the integration unit 4 is defined as a third frequency divider, capable of receiving the second-stage frequency divider signal B2 (i.e., a signal with a frequency range of 2402MHz to 2482MHz) and the second primary-stage frequency divider signal A2 (i.e., a signal with a frequency range of 5150MHz to 7125MHz), thereby outputting an integrated output signal S2 to the wireless network module 5. In other words, the wireless network module 5 transmits and receives two signals with different frequency ranges through the integration unit 4, but this invention is not limited thereto.

[0047] For example, in other embodiments of the present invention not shown, the multi-functional antenna structure 100 may omit the integration unit 4, and the second frequency divider 3 may directly output the second primary frequency division signal A2 to the wireless network module 5 for transmission and reception.

[0048] The LTE module 6 can transmit and receive the first-level frequency division signal B1, the third-level frequency division signal B3, and the fourth-level frequency division signal B4 (via the second frequency divider 3). In other words, the LTE module can transmit and receive a portion of the multiple secondary frequency division signals.

[0049] In practical use, the broadband antenna 1, the first frequency divider 2, the second frequency divider 3, and the integration unit 4 are integrated onto the same independent substrate B, thereby enabling coaxial connection to another circuit board carrying the wireless network module 5 and the LTE module 6. Accordingly, the multi-functional antenna structure 100, through the above configuration design, enables the multi-functional antenna structure 100 to achieve multiple functions with a single antenna (i.e., the broadband antenna 1). Furthermore, since the multi-functional antenna structure 100 uses a single antenna, it can effectively reduce size and avoid signal interference between different antennas. Additionally, the multi-functional antenna structure 100, using two frequency dividers (i.e., the first frequency divider 2 and the second frequency divider 3), can effectively reduce noise interference compared to a multi-functional antenna structure using a single frequency divider. Of course, in other embodiments not shown, the multi-functional antenna structure 100 may also have multiple frequency dividers.

[0050] [Second Embodiment]

[0051] like Figure 2As shown, the multi-functional antenna structure 100' of the second embodiment is similar to the multi-functional antenna structure 100' of the first embodiment described above. The similarities between the two embodiments will not be repeated. The main difference between this embodiment and the multi-functional antenna structure 100' of the first embodiment is that the multi-functional antenna structure 100' also includes a shunt 7 disposed on the substrate B, and the integration unit 4 includes a third frequency divider 41 and an integrator 42 electrically coupled to the third frequency divider 41.

[0052] Specifically, in this embodiment, after receiving the antenna signal S1, the first frequency divider 2 will output the antenna signal S1 as a first primary frequency divider signal A1 of 617MHz to 2690MHz and a second primary frequency divider signal A2 of 3300MHz to 7125MHz respectively.

[0053] Secondly, the second frequency divider 3 can receive the first primary frequency divider signal A1 and output the first primary frequency divider signal B1 of 617MHz to 2400MHz, the second primary frequency divider signal B2 of 2402MHz to 2482MHz, the third primary frequency divider signal B3 of 2500MHz to 2690MHz, and the fourth secondary frequency divider signal B4 of 3300MHz to 4200MHz.

[0054] The splitter 7 receives the first-level frequency division signal B1, the third-level frequency division signal B3, and the fourth-level frequency division signal B4 and forwards them to the LTE module 6. The splitter 7 further splits the fourth-level frequency division signal B4 (i.e., a signal with a frequency range of 3300MHz to 4200MHz) to the third frequency divider 41 of the integration unit 4.

[0055] Additionally, the third frequency divider 41 receives the second primary frequency divider signal A2 and the fourth secondary frequency divider signal B4 and outputs a temporary integrated signal K (i.e., a signal with a frequency range of 5150MHz to 4200MHz) to the integrator 42. In other words, the third frequency divider 41 divides the signal with a frequency range of 3300MHz to 7125MHz and the signal with a frequency range of 3300MHz to 4200MHz to output a signal with a frequency range of 5150MHz to 4200MHz.

[0056] The integrator 42 integrates the second-stage frequency division signal B2 and the temporary integration signal K to output the output integrated signal S2 with a frequency range of 2402MHz to 2482MHz and 5150MHz to 7125MHz to the wireless network module 5.

[0057] It is worth noting that the multifunctional antenna structure 100' also includes a DC blocker 8, and the broadband antenna 1 is electrically coupled to the first frequency divider 2 through the DC blocker 8, thereby isolating DC voltage to avoid signal interference. Furthermore, the multifunctional antenna structure 100' further includes an inductor 9 (e.g., an RF Choke), which is electrically coupled between the DC blocker 8 and the broadband antenna 1 to output a DC signal L (e.g., a 500kHz DC signal) to a sensor 200 (e.g., a proximity sensor), but the invention is not limited thereto.
