Abstract

An isotropic antenna system includes a first antenna for transmitting/receiving electric waves when a cover member installed to be capable of being open or closed with respect to a main body is open, a second antenna for transmitting/receiving electric waves when the cover member is closed, and a switching portion for selectively switching at least one of the first and second antennas to a predetermined RF circuit module according to the opening or closing of the cover member.

Claims

1. An isotropic antenna system comprising:

a computer having a cover member with a computer display, a main body, a first antenna, a second antenna, an RF circuit module, and a switch;

said first antenna being mounted on said cover member;

said second antenna being mounted on said computer at one of said cover member and said main body; and

said switch selectively switching at least one of the first and second antennas to operably connect to the RF circuit module based on an opening state of said cover member of said computer with respect to said main body.

2. The system as claimed in claim 1, wherein:

the first antenna is a dipole antenna, and

said cover member is adapted so that said first antenna is movable from a position with a tip of said first antenna protruding above said cover member to a position with the tip not protruding above said cover member.

3. The system as claimed in claim 1, wherein the second antenna is a strip line antenna installed in the main body.

4. An isotropic antenna system comprising:

a computer having a cover member with a computer display a main body, a first antenna, a second antenna, an RF circuit module, and a switch;

said first antenna being mounted on said cover member;

said second antenna being mounted on said computer at one of said cover member and said main body;

said switch selectively switching at least one of the first and second antennas to operably connect to the RF circuit module based on an opening state of said cover member of said computer with respect to said main body; and

a switch button capable of elastically protruding or retreating as the cover member is open or closed so that the first antenna or the second antenna is connected to the switch.

5. A notebook computer comprising:

a computer main body;

a cover member with a display for displaying an image, the cover member is closeably installed at the computer main body;

a first antenna, installed at the cover member,

a second antenna, installed at one of the computer main body and the cover member; and

a switch selectively switching at least one of the first and second antennas to a predetermined RF circuit module according to an opening state of the cover member,

wherein electric waves are communicated by at least one of said first antenna and said second antenna in any opening state of the cover member.
