Description
Technical Field
The invention belongs to the field of antennas, and particularly relates to a coupled fence antenna.
Background
As portable electronic devices (such as wireless headsets and wearable devices) are designed toward smaller volume, the components of the portable electronic devices are compressed in a smaller space, wherein the antenna applied to the portable electronic devices needs to be adapted to a specific operating frequency and maintain good receiving and transmitting efficiency, so the selection and design of the antenna pattern often affects the efficiency of the antenna, which is a goal of the efforts of various manufacturers at present.
Disclosure of Invention
The invention aims to provide a coupling type fence antenna which can be manufactured into a small-size antenna and has directivity.
To achieve the above object, the coupled fence antenna of the present invention comprises a substrate, a monopole antenna assembly and a coupling fence unit; the substrate is provided with a top surface and a bottom surface; the monopole antenna component is formed on the top surface of the substrate and used for transmitting a first current, and is provided with a feed point, a radiator and a fence conductor which respectively extend from the feed point; the coupling fence monomer is formed on the bottom surface of the substrate and opposite to the monopole antenna component for transmitting a second current. The first current transmission direction on the radiator and the fence conductor is opposite to the second current transmission direction on the coupling fence monomer.
Thus, the coupled fence antenna of the present invention can be applied in a limited space, and the current directions of the monopole antenna component and the coupled fence unit are opposite to each other by using the design of the monopole antenna component and the coupled fence unit, so that the electric fields of the far fields are mutually cancelled, and the current is radiated by the radiator of the monopole antenna component.
In addition, the coupling fence antenna can also achieve antenna frequency reduction by means of the fence conductors of the monopole antenna components and the coupling capacitors generated between the coupling fence monomers opposite to the fence conductors.
Preferably, the coupling fence unit has a plurality of slots, so that the flow direction of the second current and the radiation direction of the antenna are changed by the slots.

Detailed Description
The following describes the components and the achieved effect of the coupled fence antenna according to the present invention by referring to the drawings and the corresponding preferred embodiments. The components, dimensions and appearance of the coupled fence antenna in the drawings are only used for illustrating the technical features of the present invention, and do not limit the present invention.
As shown in fig. 1, the coupled fence antenna 10 of the present invention includes a substrate 11, a monopole antenna element 13 and a coupling fence unit 15.
The substrate 11 has a top surface 111 and a bottom surface 113. The substrate 11 may be a Flame Retardant 4 (FR-4) or other insulating board. In this embodiment, the substrate 11 has a dimension of about 7 by 7 millimeters (mm).
The monopole element 13 is formed on the top surface 111 of the substrate 11, as shown in fig. 2, the monopole element 13 is configured to transmit a first current and has a feeding point 131 and a radiator 132 and a fence conductor 133 respectively extending from the feeding point 131. The coupling fence unit 15 is formed on the bottom surface 113 of the substrate 11 and is used for transmitting a second current, which is a coupling current, opposite to the monopole antenna assembly 13. The first current transmission direction of the radiator 132 and the fence conductor 133 is opposite to the second current transmission direction of the coupling fence unit 15, and the length of the coupling fence antenna 10 is greater than the width of the coupling fence antenna 10, so that the electric fields in far fields (far-field) cancel each other. The coupled fence antenna 10 of the present invention transmits and receives rf signals only through the radiator 132 of the monopole antenna element 13.
Furthermore, the monopole element 13 is opposite to the coupling fence unit 15, so that the frequency reduction can be achieved by the coupling capacitance between the fence conductor 133 and the coupling fence unit 15.
As shown in fig. 2, the radiator 132 of the monopole element 13 has a transverse radiating section 134 and a longitudinal radiating section 135. The fence conductor 133 has a transverse connecting section 136, a longitudinal connecting section 137 and a plurality of transversely extending sections 138, which are separated by dashed lines for clarity of definition of the sections and components, but in practice the monopole element 13 is integrally formed so that no dashed lines are present. The feed point 131 is one end of the connecting transverse radiating section 134. The longitudinal radiating section 135 is bent back and forth from the other end of the transverse radiating section 134 toward the longitudinal direction. Longitudinal connecting segment 137 extends from transverse radiating segment 134 to transverse connecting segment 136. The transverse extending segments 138 respectively extend from the longitudinal connecting segment 137 to the longitudinal radiating segment 135, and are spaced side by side and located between the transverse radiating segment 134 and the transverse connecting segment 136. The monopole element 13 further has a short-circuit conductor 139, and the short-circuit conductor 139 extends from the transverse radiating section 134 to a transverse extending section 138 adjacent to the transverse radiating section 134, so that the frequency of the coupled fence antenna of the present invention can be changed by the position of the short-circuit conductor 139. In fig. 2, the short-circuit conductor 139 is separated by a broken line for clarity, but in practice, the monopole antenna element 13 is integrally formed, so that the broken line does not exist.
In this embodiment, the antenna frequency may be adjusted in a range between about 800MHz and 1 GHz. A higher antenna frequency is obtained the closer the short-circuit conductor 139 is to the longitudinal radiating section 135, and conversely a lower antenna frequency is obtained the further the short-circuit conductor 139 is from the longitudinal radiating section 135.
As shown in fig. 3, the coupling fence unit 15 has a plurality of slots 151, and since the coupling fence unit 15 is provided with the slots 151, the second current flowing from the coupling fence unit 15 changes its flowing direction due to the slots 151, in other words, the coupling fence antenna of the present invention can change its current direction by adjusting the number, shape and size of the slots 151 of the coupling fence unit 15, thereby controlling the directivity of the antenna.
As shown in fig. 4, the substrate is omitted and the coupling fence unit 15 is shown by a dotted line. The projected position of the slot 151 of the coupling fence unit 15 overlaps the transverse connection section 136 of the fence conductor 133, a part of the transverse extension section 138 and a part of the longitudinal radiation section 135 of the radiator 132, so that the coupled fence antenna 10 of the present invention is suitable for bluetooth applications, i.e. the operation frequency can be operated at 2.4 GHz. Although the projected position of the slot 151 overlaps the transverse connecting segment 136, the transverse extending segment 138 and the longitudinal radiating segment 135 in this embodiment, in practice, the projected position of the slot 151 may only overlap the transverse connecting segment 136 and a part of the longitudinal radiating segment 135, so the embodiment is not limited to the embodiment shown in fig. 4.
As shown in fig. 5, which is a return loss (return loss) diagram of the coupled fence antenna of the present invention. In this embodiment, the coupled fence antenna of the present invention can be applied to a bluetooth antenna, i.e. the antenna has a frequency of 2.4GHz and an operating band of about 2.4-2.483 GHz. As can be seen from fig. 4, the monopole elements and the coupling fence monomers of the coupled fence antenna of the present invention can be formed in the net-shaped area of a small space (i.e., 7 × 7mm substrate size), and can be applied to bluetooth antennas.
In summary, since the coupled fence antenna of the present invention is directly formed on the substrate by the printed circuit board, the coupled fence antenna of the present invention is easy to manufacture, and has the advantages of low manufacturing cost and planarization.
Finally, it is emphasized that the components disclosed in the foregoing embodiments are merely examples, which are not intended to limit the scope of the present disclosure, and that other equivalents and modifications may be made thereto.
