Definitions
- the disclosure relates to a multi-feeding antenna and an electronic device including the same.
- Electronic devices may support various wireless communication services such as long term evolution (LTE), wireless fidelity (Wi-Fi), near field communication (NFC), and Bluetooth®, and may include at least one antenna device for supporting various frequencies of various wireless communication services.
- LTE long term evolution
- Wi-Fi wireless fidelity
- NFC near field communication
- Bluetooth® Bluetooth®
- the volume and number of antenna radiators mounted therein may be determined according to a frequency, a bandwidth, and a type of each service.
- the antenna device may use a low band ranging from 700 megahertz (MHz) to 1000 MHz, a mid band ranging from 1700 MHz to 2200 MHz, and a high band ranging from 2200 MHz to 2700 MHz as a main communication band.
- various wireless communication services such as Bluetooth® (BT), global positioning system (GPS), and wireless fidelity Wi-Fi may be used.
- an electronic device may adopt a multiple-input multiple-output (MIMO) method using a plurality of antennas having the same frequency band, and thus may realize increased data processing speed and reliability, without additional radio frequency (RF) consumption. Therefore, the MIMO method may solve existing problems of wireless communication, such as signal attenuation, interference increase, and spectrum restriction.
- MIMO method since the MIMO method has to use the plurality of antennas, it may be used in a large electronic device such as a base station, but it may be difficult to apply the MIMO to a slimmer portable electronic device, such as a smart phone.
- isolated mode antenna technology using a plurality of feeding points for a single antenna may be applied, and may provide high electromagnetic (EM) isolation, low correlation, and high radiation efficiency, compared to a related-art system feeding a plurality of antennas.
- EM electromagnetic
- Such an electronic device includes a signal antenna pattern disposed on a structure, such as an antenna carrier, and different regions of the antenna pattern are respectively fed, and thus, operate in the same frequency band such that data transmission and reception efficiency can be enhanced.
- respective feeding regions are electrically connected with one another by an isolation pattern, which corresponds to an electric length by which an electric field is minimized, which ensures high EM isolation between two radiation regions.
- antenna regions formed by respective patterns operate in multiple bands including a first frequency band, such as a 2.4 GHz band, and a second frequency band, such as a 5 GHz band isolation in the first frequency band would be possible, but the second frequency band would cause performance degradation.
- the second frequency band is tuned, performance degradation in the first frequency band is caused, thus requiring the electronic device to frequently perform a trade-off.
- the antenna radiation pattern formed only in the structure accompanying a restriction to a disposal space may incur degraded radiation efficiency due to interference by the display.
- An aspect of the present disclosure is to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a multi-feeding antenna implemented to reduce radiation performance degradation in multiple bands, and an electronic device including the same.

- the processor 120 may determine whether a call is connected over a circuit switched (CS) service network using caller identification information, such as a caller phone number of the second generation (2G) or a 3rd generation (3G) network. For example, the processor 120 receives incoming call information, such as a CS notification message or a paging request message of the CS service network over the LTE network, such as circuit-switched fallback (CSFB), and receives incoming call information, such as a paging request message over the CS service network, such as single radio LTE (SRLTE).

When the caller identification information is not included in the blacklist, the processor 120 may connect the voice call by connecting to the CS service network. When the caller identification information is included in a second reception control list, such as a white list, the processor 120 may connect the voice call by connecting to the CS service network.

For example, when the caller identification information is included in the blacklist, the processor 120 restricts the voice call connection and resumes the LTE network connection. When the caller identification information is not included in the he blacklist, the processor 120 may connect the voice call by connecting to the CS service network. For example, when the caller identification information is included in the white list, the processor 120 connects the voice call by connecting to the CS service network.

Abstract
Disclosed is an electronic device which may provide a multi-feeding antenna operating in multiple frequency bands by reducing performance degradation, and can contribute to slimness by implementing at least a portion of the patterns in a printed circuit board.
Description
The disclosure relates to a multi-feeding antenna and an electronic device including the same.
As functional differentials between electronic devices of various manufacturers have noticeably decreased, slimmer electronic devices are being developed in order to meet consumers' demands. Yet, such electronic devices are increasing in rigidity and improved design aspects.
Electronic devices may support various wireless communication services such as long term evolution (LTE), wireless fidelity (Wi-Fi), near field communication (NFC), and Bluetooth®, and may include at least one antenna device for supporting various frequencies of various wireless communication services.
In an antenna device used in an electronic device, the volume and number of antenna radiators mounted therein may be determined according to a frequency, a bandwidth, and a type of each service. For example, the antenna device may use a low band ranging from 700 megahertz (MHz) to 1000 MHz, a mid band ranging from 1700 MHz to 2200 MHz, and a high band ranging from 2200 MHz to 2700 MHz as a main communication band. In another example, various wireless communication services such as Bluetooth® (BT), global positioning system (GPS), and wireless fidelity Wi-Fi may be used.
In order to provide a wireless communication service on par with wired communication, an electronic device may adopt a multiple-input multiple-output (MIMO) method using a plurality of antennas having the same frequency band, and thus may realize increased data processing speed and reliability, without additional radio frequency (RF) consumption. Therefore, the MIMO method may solve existing problems of wireless communication, such as signal attenuation, interference increase, and spectrum restriction. However, since the MIMO method has to use the plurality of antennas, it may be used in a large electronic device such as a base station, but it may be difficult to apply the MIMO to a slimmer portable electronic device, such as a smart phone.
As a solution to these problems, isolated mode antenna technology (iMATTM) using a plurality of feeding points for a single antenna may be applied, and may provide high electromagnetic (EM) isolation, low correlation, and high radiation efficiency, compared to a related-art system feeding a plurality of antennas.
Such an electronic device includes a signal antenna pattern disposed on a structure, such as an antenna carrier, and different regions of the antenna pattern are respectively fed, and thus, operate in the same frequency band such that data transmission and reception efficiency can be enhanced. In this case, respective feeding regions are electrically connected with one another by an isolation pattern, which corresponds to an electric length by which an electric field is minimized, which ensures high EM isolation between two radiation regions. However, if antenna regions formed by respective patterns operate in multiple bands including a first frequency band, such as a 2.4 GHz band, and a second frequency band, such as a 5 GHz band isolation in the first frequency band would be possible, but the second frequency band would cause performance degradation. In addition, if the second frequency band is tuned, performance degradation in the first frequency band is caused, thus requiring the electronic device to frequently perform a trade-off.
In addition, as a display region of a conductive material is gradually extended on the front surface of the electronic device, the antenna radiation pattern formed only in the structure accompanying a restriction to a disposal space may incur degraded radiation efficiency due to interference by the display.
As such, there is a need in the art for an antenna that obviates such performance degradation in an electronic device.
An aspect of the present disclosure is to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below. Accordingly, an aspect of the present disclosure is to provide a multi-feeding antenna implemented to reduce radiation performance degradation in multiple bands, and an electronic device including the same.

FIG. 1 illustrates an example network environment including an electronic device, according to an embodiment.
Referring to FIG. 1, the network environment includes an electronic device 101, which includes a bus 110, a processor 120 including processing circuitry, a memory 130, an input/output interface 150 including input/output circuitry, a display 160, and a communication interface 170 including communication circuitry. Alternatively, the electronic device 101 may omit at least one of the illustrated components and/or include additional components.
The bus 110 is a circuit for connecting the components 120 through 170 and delivering communications such as a control message therebetween.
The processor 120 may include various processing circuitry, such as at least one of a dedicated processor, a CPU, an application processor (AP), and/or a communication processor (CP), and processes an operation or data on control of and/or communication with another component of the electronic device 101.

In addition, when a general purpose computer accesses code for implementing the processing shown herein, the execution of the code transforms the general purpose computer into a special purpose computer for executing the processing shown herein.
The processor 120, which can be connected to an LTE network, may determine whether a call is connected over a circuit switched (CS) service network using caller identification information, such as a caller phone number of the second generation (2G) or a 3rd generation (3G) network.

When receiving an incoming CS notification message or a paging request message of the CS service network over the LTE network, the processor 120 may obtain caller identification information from the incoming call information, may display the caller identification information on the display 160, and may determine whether to connect the call based on input information corresponding to the caller identification information displayed on the display 160. For example, when detecting input information corresponding to an incoming call rejection, through the input/output interface 150, the processor 120 may restrict the voice call connection and maintain the LTE network connection. When detecting input information corresponding to an incoming call acceptance, through the input/output interface 150, the processor 120 may connect the voice call by connecting to the CS service network.
When receiving the incoming CS notification message or a paging request message of the CS service network over the LTE network, the processor 120 may obtain caller identification information from the incoming call information and may determine whether to connect the call by comparing the caller identification information with a reception control list. For example, when the caller identification information is included in a first reception control list, such as a blacklist, the processor 120 may restrict the voice call connection and maintain the connection to the LTE network. When the caller identification information is not included in the blacklist, the processor 120 may connect the voice call by connecting to the CS service network. When the caller identification information is included in a second reception control list, such as a white list, the processor 120 may connect the voice call by connecting to the CS service network.
When receiving the incoming call information, such as a paging request message of the CS service network over the LTE network, the processor 120 may send an incoming call response message, such as a paging response message, to the CS service network, may suspend the LTE service and receive the caller identification information, such as a circuit-switched call (CC) setup message, from the CS service network, and may determine whether to connect the call by comparing the caller identification information with the reception control list. For example, when the caller identification information is included in the blacklist, the processor 120 restricts the voice call connection and resumes the LTE network connection. When the caller identification information is not included in the he blacklist, the processor 120 may connect the voice call by connecting to the CS service network. For example, when the caller identification information is included in the white list, the processor 120 connects the voice call by connecting to the CS service network.

Referring to FIG. 7, the multi-feeding antenna 500 may include the first conductive pattern 530 disposed in a first portion A1 of the PCB 520, the second pattern 540 disposed in a second portionA2 of the PCB 520, and the conductive path 550 disposed in the PCB 520 to electrically connect the first conductive pattern 530 and the second conductive pattern 540.

According to embodiments, an end of the first conductive pattern 530 may be connected to the ground plane 521 by a matching circuit 5211.

The second conductive pattern 840 may operate in the second frequency band, and a second metal member 811 used as the side surface member 810 may receive a feeding signal and operate in the first frequency band with the fourth conductive pattern 870.
The conductive path 850 disposed in the PCB region and electrically connecting the first conductive pattern 830 and the second conductive pattern 840 may be used as an isolation pattern between the two antenna regions, and may include elements A 851, B 852 disposed to perform a filtering role to enable only a specific frequency, such as the first frequency, to pass therethrough in order to guarantee smooth isolation between antenna regions and reduce mutual interference by different frequency bands operating in respective antenna regions. The elements A 851, B 852 may include a matching circuit or a low pass filter.

The first antenna region and the second antenna region of the multi-feeding antenna smoothly operate in multiple frequency bands of the first frequency band and the second frequency band.
FIG. 9C is a graph showing an S21 isolation value ISI between a first antenna and a second antenna, and illustrates that an isolation loss which indicates a degree of interference between the two antennas is less than or equal to 10 dB, which is a normal level. Good performance between the two antennas is illustrated in FIG. 9A.
