Abstract:
An antenna apparatus for a portable terminal having a main board is provided. The antenna apparatus includes a main antenna that electrically connects to a feed line of the main board. A metal frame is constructed as part of a case frame forming an exterior of the portable terminal. The metal frame is divided into first and second parts that are separated. The first part electrically connects to the main antenna or to the main board feed line, and is designed to radiate. The second part electrically connects to a ground surface of the main board. The metal frame enhances overall antenna performance rather than causing degradation through interference.
Abstract:
An example antenna device may includes a base member, an antenna that is attached to the base member, and a cover member that is attached to surround at least a part of the base member and at least a part of the antenna. A first part of the base member that is attached to the cover member has a melting temperature equal to or lower than that of the cover member. A second part of the base member to which the antenna is attached has a higher melting temperature than the cover member.
Abstract:
An antenna apparatus for an electronic device is provided. The antenna apparatus includes a broadcasting antenna apparatus for receiving broadcasting, and a communicating antenna radiator arranged near the broadcasting antenna apparatus and fed simultaneously from a feed part of the broadcasting antenna apparatus. The communicating antenna radiator is able to maintain the same performance irrespective of an operation of the broadcasting antenna apparatus, thereby improving a reliability and usability of the device and making a contribution to the minimizing of a size of the device.
Abstract:
A portable terminal is provided. The portable terminal includes a main housing, a sub housing, a mainboard, and an electric connector. The main housing has a first antenna radiator. The sub housing is separable from the main housing and has a second antenna radiator. The mainboard is disposed in the main housing and processes a radio signal. The electric connector is disposed in the main housing. When the sub housing and the main housing are separated from each other, the electric connector electrically connects the mainboard with the first antenna radiator of the main housing. When the sub housing and the main housing are coupled, the electric connector electrically connects the mainboard with the second antenna radiator of the sub housing.

An electronic device is provided. The electronic device includes a front cover forming a front surface, a rear cover forming a rear surface, a sidewall at least partially enclosing a space formed between the front cover and the rear cover and at least partially formed of a conductive member, a display disposed in the space and including a screen region exposed through the front cover, a non-conductive structure disposed in adjacent to the sidewall or in contact with the sidewall in the space and including a first surface facing the front cover and a second surface facing the rear cover, a first antenna pattern overlapping the non-conductive structure and fed with electricity, a second antenna pattern overlapping the non-conductive structure and disposed adjacent to the first antenna pattern to form electromagnetic-field coupling with the first antenna pattern, and an integrated circuit chip feeding electricity to the first antenna pattern
Abstract:
An apparatus interworking with a metal member used both as an antenna and a sensor element in a portable terminal is disclosed. The apparatus includes the metal member, responsive to a sensed body, and for transmitting and receiving a signal in at least one or more communication service bands, and a main board having a communication module for processing a signal transmitted and received by the metal member and a sensor module for obtaining information in response to the approach of a sensed body.
Abstract:
A built-in antenna apparatus for a electronic device is provided. The antenna apparatus comprises a PCB with conductive and non-conductive areas. An antenna radiator is disposed at the non-conductive area of the PCB; the antenna radiator has a feeding portion and at least a first radiating portion configured in a first pattern branched from the feeding portion and has an end portion electrically connected to the conductive area. At least one capacitor is electrically connected in series within the first radiating portion. A resonant frequency of the first radiating portion is a function of a capacitance value of the at least one capacitor. The antenna can be provided in a smaller size for a given frequency band due to the capacitance. A second antenna radiator branched from the feeding portion can also be provided for operation at a different frequency band.
