A mobile communication device is provided and includes a plastic frame body, a metal outer frame, a metal inner frame and a first conductive spring. The plastic frame body has an opening, a first locking groove, a first inserting groove and a first protrusive portion formed between the first locking groove and the first inserting groove. The metal outer frame is locked to the first locking groove and fixed on the outside of the plastic frame body. The metal inner frame is inserted into the first inserting groove and fixed in the surroundings of the opening of the plastic frame body. Besides, the metal inner frame is electrically connected to a system ground plane. The first conductive spring clasps the first protrusive portion. The first conductive spring extends into the first locking groove and the first inserting groove so as to electrically connect the metal outer and inner frames.

Mobile communication device

A handheld device is disclosed, which includes an appearance part, a system ground plane and a detachable element. The detachable element includes a carrier and a planar antenna. The system ground plane is disposed in the appearance part and has a feed point. The planar antenna is disposed on the carrier and has a connection point. The carrier is detachably connected to the appearance part. When the carrier is connected to the appearance part, the above-mentioned connection point is electrically connected to the feed point. In this way, the radiation performance of the antenna can be improved and the frequency band of the antenna of the handheld device can be changed by replacing the detachable element.

Handheld device

A PIFA/monopole hybrid antenna includes a high-frequency radiator, a low-frequency radiator, a connecting part, a feed part, and a ground part. The high-frequency radiator includes a first radiating part and a second radiating part extended substantially perpendicular to the first radiating part. The low-frequency radiator includes a third radiating part extended substantially parallel to the first radiating part, and a fourth radiating part extended substantially perpendicular to the third radiating part. The connecting part is connected between the high-frequency radiator, the low-frequency radiator, the connecting part, the feed part, and the ground part.

PIFA/monopole hybrid antenna and mobile communications device having the same

A PIFA for a thin communication apparatus is provided. The PIFA includes a main body, a ground area and two ground segments, wherein the ground segments are adjacent with each other and extending out from a same side of the ground area. The SAR value and a required height for setting the antenna can be reduced through the design of two grounding paths on the antenna.

Antenna for thin communication apparatus

A mobile apparatus is provided. The mobile apparatus includes an antenna and a ground plane. The antenna is used to receive or transmit a radio frequency signal and includes a grounding part having a first ground terminal and a second ground terminal. Wherein, a distance between the first ground terminal and the second ground terminal is associated with a wavelength of the radio frequency signal. The ground plane is electrically connected to the grounding part of the antenna through the first ground terminal and the second ground terminal. The present invention effectively reduces a specific absorption ratio and a required height for setting the antenna such that a bandwidth of the antenna is increased.

Mobile apparatus

An antenna device including a ground plane, a circuit board, an antenna, and a conductive wire is provided. The circuit board includes a signal feed point, and the antenna includes a radiation portion and a feed portion extending externally from the radiation portion. The feed portion is electrically connected to the signal feed point, and the conductive wire is disposed on the circuit board and electrically connected to the ground plane and the signal feed point. The conductive wire is, for example, a printed trace formed on the circuit board.

Antenna device

A mobile communications device includes a circuit board and a monopole antenna. The monopole antenna includes a feed part electrically connected to the circuit board and directed away from the circuit board at an acute angle, a connecting part extending from the feed part in a direction substantially perpendicular to the circuit board, a first radiating part extending from the connecting part, and a second radiating part also extending from the connecting part.
