It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
It is to be noted that, unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Fig. 1 is a schematic diagram illustrating a structure of a conventional smart partition antenna, which is shown in a dotted structural part in fig. 1. The input room division signal and the signal output by the intelligent hardware are combined in the combining circuit to form a corresponding combined signal output. The combined signal is output to the intelligent indoor branch antenna through the power divider, and indoor signal coverage is carried out by the intelligent indoor branch antenna. In practical applications, the inventor finds that, in the process of fusing the intelligent hardware with the passive distributed system, the introduction of the intelligent hardware can deteriorate the passive intermodulation performance of the antenna in the passive distributed system. The passive intermodulation of the antenna is a key index, and can affect the signal receiving performance of other communication equipment in the passive distributed system. Therefore, in engineering application, when an intelligent indoor distribution system is built, it is very important to ensure the passive intermodulation index of the antenna. To the relatively poor problem of passive intermodulation performance that traditional wisdom room branch system exists, the embodiment of the utility model provides a following technical scheme:
referring to fig. 2, in one embodiment, a smart-room antenna apparatus 100 is provided, which includes smart hardware 12, a combining circuit 14, an antenna 16, and a filtering circuit 18. One input port of the combining circuit 14 is electrically connected to the intelligent hardware 12 through the filter circuit 18. The other input port of combining circuit 14 is for receiving a chamber division signal. An output port of the combining circuit 14 is connected to an antenna 16. The filter circuit 18 is used to filter out intermodulation products generated by the intelligent hardware 12 and reject out-of-band signals of the intelligent hardware 12.
It is understood that the intelligent hardware 12 is various types of intelligent hardware 12 conventional in the art, and the specific type may be determined according to the intelligent hardware 12 used in the smart room subsystem in practical applications. The intelligent hardware 12 is a unit for generating and processing signals, and mainly includes a transceiver chip, a power supply unit, and other external component circuit units, etc., and the number and structure of the external component circuit units are different from each other in different intelligent hardware 12 applied in different intelligent room subsystems, and are determined by the kind of functions provided by the specific intelligent hardware 12.
The combining circuit 14 is a circuit unit providing a signal combining function, and is configured to combine the room division signal input by the signal source with the signal output by the intelligent hardware 12, and output the combined signal to the antenna 16. The combining circuit 14 may be a two-input one-output three-port combining circuit 14, or may be a multi-input one-output or multi-input multi-output multi-port combining circuit 14, which may be determined according to the needs of practical applications. The filter circuit 18 may be a filter as is conventional in the art, or may be a module of the filter circuit 18 composed of filters, and the pass band of the filter circuit 18 may be determined by the frequency of the signal output by the intelligent hardware 12, the frequency of the intermodulation product to be filtered, the frequency of the out-of-band signal to be suppressed, and so on. The intelligent hardware 12 in different smart room subsystems will output signals at different frequencies, resulting in intermodulation products and out-of-band signals to be suppressed, and therefore the passband of the filter circuit 18 will also be different, as long as the desired filtering and suppression functions are provided. The out-of-band signals are interference signals that interfere with normal reception of signals by the intelligent hardware 12, that is, various signals whose signal frequencies are outside the bandwidth of useful signals that the intelligent hardware 12 needs to receive.
Specifically, the signal output by the intelligent hardware 12 is first filtered by the filter circuit 18, and then output from the filter circuit 18 to one input port of the combining circuit 14, while the room division signal input from the signal source is input to the combining circuit 14 from the other input port of the combining circuit 14. In the combining circuit 14, the filtered signal output by the intelligent hardware 12 and the room division signal input by the signal source are combined into one path and output to the antenna 16. The signal source may be a 2G, 3G, 4G or 5G indoor branch signal source in the art, and the link connection between the combining circuit 14 and the antenna 16 may be a direct connection or an indirect connection through an intermediate auxiliary element, which is specifically determined by the architecture of different intelligent indoor branch systems and the type of the combining circuit 14 in practical applications. The signal output by the intelligent hardware 12 is filtered through the filter circuit 18, the generated intermodulation product is filtered, and in the process that the intelligent hardware 12 receives the signal, the input signal entering the intelligent hardware 12 also passes through the filter circuit 18, so that the filter circuit 18 can effectively inhibit out-of-band signals influencing the normal signal receiving of the intelligent hardware 12, the intelligent hardware 12 is fused with a passive distributed system, and the passive intermodulation index of the indoor distribution system is obviously improved.
According to the intelligent indoor antenna device 100, through link optimization design of the intelligent hardware 12, the combining circuit 14, the antenna 16 and the filter circuit 18, when the combining circuit 14 combines the indoor signal with the output signal of the intelligent hardware 12 and outputs the combined signal to the antenna 16, the filter circuit 18 is connected to filter intermodulation products generated by the intelligent hardware 12 and suppress out-of-band signals affecting normal signal receiving of the intelligent hardware 12. Therefore, the intelligent hardware 12 is connected to the combining circuit 14 through the filter circuit 18, so that adverse effects of the intelligent hardware 12 on intermodulation of the connected passive distributed system when the intelligent hardware 12 is combined with the antenna 16 can be effectively improved, and the passive intermodulation performance is greatly improved.
In one embodiment, the filter circuit 18 is a low intermodulation filter or a microstrip filter circuit 18. It will be appreciated that in the present embodiment, the filter circuit 18 may employ a low intermodulation filter that is common or dedicated in the art, or may also employ a microstrip filter circuit 18 that is common or dedicated in the art. The particular type and electrical characteristics of the low intermodulation filter or microstrip filter circuit 18, etc., may be determined based on the intermodulation products generated by the smart hardware 12 and the out-of-band signals that are desired to be suppressed. The number of the low intermodulation filter devices or the microstrip filter circuits 18 provided in the smart room antenna apparatus 100 may be one or more. For example, when there are a plurality of intelligent hardware 12, a plurality of low intermodulation filter devices or microstrip filter circuits 18 may be respectively disposed, and each low intermodulation filter device or microstrip filter circuit 18 is correspondingly connected to one intelligent hardware 12, so as to respectively implement filtering of intermodulation products and suppression of out-of-band signals of different intelligent hardware 12. Or for example, a multiple-input multiple-output low intermodulation filter or microstrip filter circuit 18 is connected to a plurality of intelligent hardware 12, so as to filter intermodulation products and suppress out-of-band signals of the plurality of intelligent hardware 12.
By applying the low intermodulation filter or the microstrip filter circuit 18, the fusion of the indoor subsystem and the intelligent hardware 12 can be effectively realized, the passive intermodulation index of the intelligent indoor subsystem can be improved, and the effects of simple design, low cost, small occupied equipment space and wide application to various indoor antennae 16 can be realized.
In one embodiment, combining circuit 14 is a microstrip coupler, a low intermodulation combiner, or a low intermodulation bridge. It is understood that microstrip couplers, low intermodulation combiners, or low intermodulation bridges commonly used or dedicated in the art may be employed in this embodiment to achieve the combination of the room division signal with the signal output by the intelligent hardware 12 through the filter circuit 18.

The specific type and electrical characteristics of the single-polarized antenna, the dual-polarized antenna or the spot lamp antenna can be selected according to the signal coverage requirement. The intelligent indoor subsystems in different application scenarios are different, and the required signal coverage functions are different, so that different types of antennas 16 can be selected according to the actual application scenarios, as long as the indoor signals in the applied intelligent indoor subsystems and the signal coverage functions of the intelligent hardware 12 can be effectively realized. In the above-mentioned types of antennas 16, the number of any one of the antennas 16 may be plural, and the specific number may be determined by the range size and the coverage strength of the signal coverage. By applying a single polarized antenna, a dual polarized antenna, or a spot lamp antenna without additionally designing a new antenna 16, the manufacturing and application costs of the smart partition antenna device 100 can be reduced better.
