Abstract

The disclosure relates to a communication technique for merging an IoT technology with a 5th Generation (5G) communication system for supporting a higher data transmission rate than a 4th Generation (4G) system, and a system therefor. The disclosure can be applied to intelligent services (for example, smart homes, smart buildings, smart cities, smart cars or connected cars, healthcare, digital education, retail, security- and safety-related services, and the like) on the basis of 5G communication technologies and IoT-related technologies. An electronic device is provided. The electronic device includes a board, a plurality of antenna arrays arranged on the board, and a plurality of floating radiator arrays arranged on the board to be spaced apart from the plurality of antenna arrays by a predetermined distance. The plurality of floating radiator arrays are electromagnetically coupled to the plurality of antenna arrays.

First claim

What is claimed is:

1. An antenna module comprising:
a board;
an antenna array including a plurality of sub-arrays, wherein each of the plurality of sub-arrays includes antenna elements arranged in a line along a designated direction; and
a plurality of floating radiator arrays arranged to be spaced apart from the plurality of sub-arrays by a first distance on the board,
wherein each of the plurality of floating radiator arrays includes floating radiators arranged in a line along the designated direction,
wherein the plurality of floating radiator arrays are arranged alternatively with the plurality of sub-arrays on the board,
wherein each of the floating radiators is formed in a ring shape, and
wherein the plurality of floating radiator arrays are configured to be electromagnetically coupled to the antenna array.

2. The antenna module of claim 1 ,
wherein the antenna module further comprises:
feeding circuitry configured to supply an electrical signal to the antenna array,

wherein the antenna array is configured to radiate a first electromagnetic wave, based on the electrical signal,
wherein a first floating radiator array of the plurality of floating radiator arrays is disposed on a first side of a first sub-array of the antenna array, and
wherein a second floating radiator array of the plurality of floating radiator arrays is disposed on a second side of the first sub-array.

3. The antenna module of claim 2 , wherein the first floating radiator array among the plurality of floating radiator arrays is disposed to be spaced apart from the first side of the first sub-array of the antenna array by the first distance.

4. The antenna module of claim 3 , wherein the second floating radiator array among the plurality of floating radiator arrays is disposed to be spaced apart from the second side of the first sub-array of the antenna array by the first distance.

5. The antenna module of claim 1 , wherein the ring shape comprises at least one of a rectangular ring shape, a circular ring shape, or a diamond-shaped ring shape.

6. The antenna module of claim 4 ,
wherein the second floating radiator array among the plurality of floating radiator arrays is disposed to be spaced apart from a first side of a second sub-array of the antenna array by the first distance, and
wherein a distance between the first floating radiator array and the second floating radiator array is greater than a distance between the first sub-array and a second sub-array.

7. The antenna module of claim 2 , wherein the first sub-array is connected to the feeding circuitry.

8. The antenna module of claim 1 , wherein each of the floating radiators has a capacitance and at least one inductance.

9. The antenna module of claim 8 ,
wherein the at least one inductance comprises a first inductance to a fourth inductance, and
wherein the capacitance and the first inductance to the fourth inductance are determined according to at least one of a horizontal length and a vertical length of a corresponding floating radiator.

10. The antenna module of claim 9 , wherein a phase of an electromagnetic wave radiated from a corresponding floating radiator is determined based on an imaginary component of the capacitance and the first inductance to the fourth inductance.

11. The antenna module of claim 8 , wherein the capacitance and the at least one inductance are determined according to at least one of a horizontal length, a vertical length, a thickness, and a line width of the corresponding floating radiator.

12. The antenna module of claim 1 , wherein upper surfaces of the antenna elements are spaced apart from an upper surface of the board by a second distance different from the first distance.

13. The antenna module of claim 12 , wherein upper surfaces of the floating radiators are spaced apart from the upper surface of the board by the second distance.

14. The antenna module of claim 13 , wherein the first distance corresponds to the second distance.
