Description

Antenna and electronic device having same

Various embodiments of the present disclosure relate to an antenna and an electronic device 100 having the same.

Recently, with the development of information and communication technology and semiconductor technology, the spread and use of electronic devices are rapidly increasing. These electronic devices provide various functions. For example, the electronic device includes a TV watching function (eg, mobile broadcasting such as Digital Multimedia Broadcasting (DMB) or Digital Video Broadcasting (DVB)), a music playback function (eg, in addition to a general mobile communication function such as voice call or message transmission and reception) , MP3 (MPEG Audio Layer-3), photo taking function, data communication function, Internet access function and/or location information providing function, etc. are provided.

Recently, electronic devices provide a plurality of wireless communication methods, and various frequency bands corresponding to the wireless communication methods are used. Recently, in order to meet the increasing demand for wireless data traffic after commercialization of the 4G (4th-Generation) communication system, a 5G communication system or a pre-5G communication system is being discussed, and in the 5G communication system or the pre-5G communication system, high frequency A method of using bands (eg, 28 gigabytes (28 GHz), 39 gigabytes (39 GHz), 60 gigabytes (60 GHz) bands) is being considered.

Meanwhile, the electronic device includes an antenna capable of receiving or transmitting (or radiating) radio waves used in a wireless communication method. Antenna is a conversion device for transmitting or receiving electromagnetic waves in a specific area.

The electronic device may include a plurality of antennas in order to transmit and receive signals of various frequency bands. However, it may be difficult to include a large number of antennas due to the lack of an antenna mounting space due to the reduction in weight and size of electronic devices.

When one antenna handles multiple frequency bands, filtering may be performed to separate radio signals received through the antenna for each frequency band. As the frequency band covered by one antenna increases, more filtering is performed, which not only complicates the design of the communication circuit, but also increases the loss generated in the filtering process. When one antenna covers many frequency bands, the corresponding antenna performance may be deteriorated.
