Abstract

A wireless device includes a first antenna element resonating with a first frequency, a first feeding point coupled to the first antenna element and disposed on a ground plane in the wireless device, a first matching circuit of which first end is coupled to the first feeding point, a second antenna element resonating a second frequency higher than the first frequency, a second feeding point coupled to the second antenna element and disposed on the ground plane, a second matching circuit of which one end is coupled to the second feeding point, and a radio circuit coupled via a transmission line to a common connection point (18) shared by respective second ends of the first and second matching circuits.

Description

technical field [0001] The present invention relates to a wireless device equipped with an antenna. In particular, it relates to wireless devices used for mobile communications such as mobile phones. Background technique [0002] In recent years, in mobile communication including mobile phones, data communication services for voice calls, text, and video are diversified, and high-performance wireless devices are required. In particular, the performance of an antenna serving as a portal for transmitting and receiving radio waves is one of the important factors affecting the performance of a wireless device, and therefore a wireless device equipped with a high-performance antenna is eagerly desired. [0003] use image 3 Such a conventional wireless device will be described. image 3 It is a diagram schematically showing a conventional wireless device equipped with an antenna. [0004] exist image 3 In , the antenna 103 and the bottom plate 108 are arranged side by side. T...
