For antennas used in a mobile electronic device or mobile terminal, the volume and number of antennas to be mounted may be determined according to a frequency, a bandwidth, and/or a type for each service. For example, a low band of about 700 MHz to 900 MHz, a mid band of about 1700 MHz to 2100 MHz, a high band of about 2300 MHz to 2700 MHz, or a high-frequency band of about 3 GHz to 300 GHz (eg 5G(NR)) It can be used as the main communication band. As another example, various wireless communication services such as bluetooth (BT), global positioning system (GPS), or wireless fidelity (WIFI) may be used. In order to support the above-described communication bands, a plurality of antennas must be included in the electronic device, whereas the electronic device that is required to be gradually slimmed may have a limited antenna volume space. In order to overcome this, a service band having a similar frequency band may be bundled and separated into multiple antennas to be designed.

For example, the antenna can be used in 2G bands (eg GSM850, EGSM, DCS, PCS), WCDMA (eg B1, B2, B5, B8), LTE bands (eg B1, B2, B3, B4, B5, B7). , B8, B12, B17, B18, B19, B20, B26, B38, B39, B40, B41) and/or Sub-6 band (e.g. n77, n78, n79). there is. When such an antenna is individually implemented to operate in all frequency bands supported by the electronic device, it may be difficult to overcome operator specification satisfaction, specific absorption rate (SAR) criterion satisfaction, and/or minimization of human impact.

According to various embodiments, an antenna capable of helping to improve radiation characteristics in a 5G (NR) band (eg, a sub-6 band) and an electronic device including the same may be provided.
