An antenna structure according to various embodiments is provided and may include a printed circuit board (PCB), a radio frequency integrated circuit (RFIC) disposed at a first surface of the PCB and a first antenna disposed at a second surface of the PCB, parallel to the first surface, and including a plurality of conductive patches. The antenna structure includes a dielectric layer adjacent to the second surface and arranged parallel to the second surface and a conductive layer disposed in the dielectric layer and including a plurality of openings formed in areas corresponding to the plurality of conductive patches, wherein the RFIC transmits/receives a signal having a specified frequency through the first antenna and the conductive layer.

Antenna structure having a conductive layer, and an electronic device including same

To control antenna characteristics in an electronic device, a method for operating the electronic device may include identifying communication states related to a first radio access technology (RAT) and a second RAT, determining a mode of a tuner which controls characteristics of an antenna for the second RAT, based on the communication states, and controlling the tuner according to the mode.

Method for controlling antenna characteristics and an electronic device thereof

Disclosed herein is an electronic device. The electronic device may include an electronic device may comprising a housing, a first PCB disposed inside the housing, a first wireless communication circuit disposed on the first PCB to transmit and receive signals of a first frequency band, a second PCB disposed inside the housing, wherein the second PCB includes a signal line, an antenna array disposed on the second PCB, a second wireless communication circuit disposed on the second PCB to transmit and receive a signal of a second frequency band using the antenna array, and a conductive member electrically connected to the first wireless communication circuit by the signal line of the second PCB via a feed point for the conductive member.

Electronic device including antenna module

A pen input device having malfunction prevention function and method of preventing malfunction thereof are disclosed. The pen input device includes: a housing having a bar form and having one end relatively narrowly opened to form a housing space; a resonant circuit housed within the housing; a tip that protrudes from an open end of the housing to the outside, the tip comprising a dielectric material and being configured to be movable within a predetermined range in a direction of a longitudinal axis of the housing, the tip being further configured to be self-centering; and a ground shielding portion formed in a portion of the housing in which electromagnetic induction occurs, the ground shielding portion not including the tip.
