Wireless device and method for improving antenna characteristic of the wireless device |
摘要 |
A wireless device includes a housing having a shielding case and a dielectric case. The housing receives a printed circuit board and an antenna element. The printed circuit board has a feeding pad, a first ground pad and a second ground pad. The antenna has a feeding portion electronically coupled with the feeding pad of the printed circuit board and a ground portion electronically coupled with the shielding case for increasing ground dimension to improve antenna characteristic. The first and second ground pads of the printed circuit board electronically coupled with the shielding case for reducing coupling effect to improve antenna characteristic.
