Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the following detailed description of the embodiments of the present invention will be described with reference to the accompanying drawings. Examples of these preferred embodiments are illustrated in the accompanying drawings. The embodiments of the invention shown in the drawings and described in accordance with the same are merely exemplary and the invention is not limited to these embodiments.
It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and/or processing steps closely related to the solution according to the present invention are shown in the drawings, and other details not so relevant to the present invention are omitted.
To the prior art in the background art, the utility model provides a following detailed description.
As shown in fig. 1, the coplanar antenna provided in this embodiment includes a radiation wall 1 and a balun structure 2 supporting the radiation wall 1. The balun structure 2 includes a chassis 21 and a balun 22 disposed on the chassis 21. The radiation wall 1 is arranged on the end of the balun 22 remote from the chassis 21. A plurality of radiation units 11 are arranged at intervals on the radiation wall 1, and two adjacent radiation units 11 are connected with each other through an inductance element 12. The balun structure 2 is provided with a feed circuit board 3 for supplying electric energy to the plurality of radiating elements 11.
In the coplanar antenna of the present embodiment, two adjacent radiation units 11 are connected to each other via an inductance element 12. The inductance element 12 can filter out electromagnetic waves between two adjacent radiation units 11 above a predetermined value. For example: the electromagnetic wave frequency band of one radiation unit is 700MHz, and the electromagnetic wave frequency band of the other radiation unit is 1GHz. When one radiating unit and the other radiating unit work simultaneously, the inductance element can filter out 1GHz electromagnetic waves, so that the interference of a relatively high-frequency radiating unit on a relatively low-frequency radiating unit is avoided, and the mutual coupling phenomenon among the radiating units is avoided.
Since the inductance element 12 between two adjacent radiation units 11 is a small-sized element, in the coplanar antenna of the present embodiment, the distance between two radiation units 11 is reduced to a distance corresponding to the size of one inductance element 12, which is beneficial to the miniaturization of the coplanar antenna.
Specifically, as shown in fig. 1, the radiation wall 1 of the present embodiment includes a first horizontal dielectric plate 1a perpendicular to the balun structure 2. The plurality of radiation units 11 are arranged on the first horizontal dielectric slab 1a at intervals along the length direction of the first horizontal dielectric slab 1a. A through hole is formed in a region of the first horizontal dielectric plate 1a located between two adjacent radiation units 11, and a coil of the inductance element 12 is inserted into the through hole, so that a distance between two adjacent radiation units 11 can be further shortened.
Further, the radiation wall 1 further includes a second horizontal dielectric plate 1b intersecting the first horizontal dielectric plate 1a. The second horizontal dielectric plate 1b is perpendicular to the balun structure 2. The radiating elements 11 are arranged on the second horizontal dielectric plate 1b at intervals along the length direction of the second horizontal dielectric plate 1b, and two adjacent radiating elements 11 are connected with each other through the inductance element 12. A through hole is formed in a region, located between two adjacent radiating units 11, of the second horizontal dielectric plate 1b, and a coil of the inductance element 12 is inserted into the through hole.
Preferably, the via in this embodiment is a metalized via.
Alternatively, the plurality of radiation elements in the present embodiment may be arranged in a transverse direction, a longitudinal direction, or an array.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrases "comprising a," "8230," "8230," or "comprising" does not exclude the presence of additional like elements in a process, method, article, or apparatus that comprises the element.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
