Abstract
The present invention aims to provide a diversity wireless device that can be downsized without reduction in diversity gains. Provision of at least one ungrounded antenna among a plurality of antennas in the device makes a lower correlation between the antennas, thus giving a high diversity gain.
Claims14
A diversity wireless device for providing diversity using a plurality of antennas comprising:
- an antenna which is grounded (grounded antenna) and an antenna which is not grounded (ungrounded antenna).
A diversity wireless device for providing diversity using a plurality of ungrounded antennas wherein
- a ground is placed in proximity to at least one of said ungrounded antennas and said ungrounded antenna is coupled to said ground via high-frequency waves.
A diversity wireless device for providing diversity using a plurality of antennas wherein
- at least one ungrounded antenna is provided, a ground is placed partly surrounding said ungrounded antenna, and said ungrounded antenna and said ground are coupled to each other via high-frequency waves.
A wireless terminal unit having an antenna element, said antenna element including:
- (a) a substrate;
- (b) a first conductor section substantially in parallel to said substrate;
- and
- (c) a second conductor section successively formed from said first conductor section and angularly arranged relative to said substrate.
