Embodiment Construction

[0018] An antenna system 10 including an embodiment of the present invention is shown in FIG. 1. The antenna system 10 includes at least an antenna structure 14, which can be attached to a supporting unit 12, and the supporting unit 12 is made of a thin and bendable material. Physical support of structure 14. Preferably, the antenna structure 14 is made of a low-resistance conductor and attached to the supporting unit 12. In this state, the antenna system 10 may be a laminate of the antenna structure 14 and the supporting unit 12.

[0019] The laminated structure shown in FIG. 1 increases the structural integrity of the antenna system 10. The supporting unit 12 does not perform a working function, and the antenna structure 14 is completely working without the supporting unit 12. When the antenna structure 14 is to be placed in another structural unit and manufactured as another unit at the same time, the antenna structure can be directly mounted on the other structural unit, so th...

Abstract

An antenna system for a portable communication device comprises an antenna structure for transmitting and receiving signals. The antenna structure includes multiple feeding ports and multiple antennas of different types having a common structure fully coupling the multiple antennas together. This antenna structure is made of a conductor that can be surface mounted over a nonplanar surface. When the conductor is mounted on a nonplanar surface, the antenna structure may extend in three dimensional space around the portable communications device.

Description

Technical field [0001] The present invention relates to an antenna capable of receiving and transmitting signals from radio frequency (RF) communication equipment, especially an antenna for portable handheld communication equipment. Background technique [0002] The antenna is a conversion element that converts circuit current into electromagnetic energy. Conversely, it can also convert level energy into circuit current. The frequency of the antenna response is based on the physical characteristics of the antenna, such as width and length. Changes in the width and length of the antenna affect the impedance of the antenna and the current density distribution along the length of the antenna. The antenna field is affected by nearby targets, such as other antennas, which will distort the antenna performance. [0003] In order to make communication devices work at different frequencies, previous designs included multiple separate antennas, each for the frequency to be operated. Due to...
