Patent ID: 8872707

Claim:
A planar multi-band antenna for tablet computers comprising: a direct-fed plurality of interconnected conductive monopole paths including: a first path receiving a feed signal, the first path having a bent part formed at a first end thereof and a chip inductor disposed at a middle portion of the first path; a second path whose two ends are extended to form a bent part and an extension part respectively while the bent part is connected to a second end of the first path; a third path in which a first bent part is formed at a first end thereof and a second bent part is formed at a second end thereof while a middle part thereof is connected to the extension part of the second path; a fourth path having a first end thereof connected to the second path; and, a coupled monopole portion being coupled to the direct-fed plurality of interconnected monopole paths, the coupled monopole portion having a plurality of interconnected conductive monopole paths including: a fifth path that is coupled to a second end of the fourth path and having two substantially symmetric ends thereof extended to form a first extension part and a second extension part respectively while the first extension part and the second extension part are corresponding and parallel to each other; a sixth path having a first bent part and a second bent part on two ends thereof respectively while the first bent part of the sixth path is connected to the first extension part of the fifth path; a seventh path that is connected to the second bent part of the sixth path; an eighth path that includes a first bent part and a second bent part formed on two ends thereof respectively; the first bent part of the eighth path is connected to the second extension part of the fifth path; and a grounding portion connected to the second bent part of the third path and the second bent part of the eighth path.
