Abstract
A flexible substrate includes a base substrate that has flexibility, connecting portions on the base substrate and connectible to an antenna substrate and a circuit substrate, and a first line and a second line at the base substrate and connected to the connecting portions. The first line and the second line include a first region in which the first line and the second line extend in parallel or substantially in parallel with each other, and a second region in which the first line and the second line are closer to each other than in the first region and coupled to each other, and the second region defines a directional coupler.
Claims21
A flexible substrate comprising:
- a base substrate that has flexibility;
- a connecting portion on the base substrate and connectible to a mounted circuit;
- and
- a first line and a second line at the base substrate and connected to the connecting portion;
- wherein
- the first line and the second line include:
- a first region in which the first line and the second line extend in parallel or substantially in parallel with each other;
- and
- a second region in which the first line and the second line are closer to each other than in the first region and coupled to each other;
- and
- a length of each of the first line and the second line in the second region is equal or substantially equal to one quarter of a wavelength of a signal that propagates through the first line and the second line.
A flexible substrate comprising:
- a base substrate that has flexibility;
- a connecting portion on the base substrate and connectible to a mounted circuit;
- and
- a first line and a second line at the base substrate and connected to the connecting portion;
- wherein
- the first line and the second line include:
- a first region in which the first line and the second line extend in parallel or substantially in parallel with each other;
- and
- a second region in which the first line and the second line are closer to each other than in the first region and coupled to each other;
- and
- the first region includes an interlayer connection conductor between the first line and the second line.
A flexible substrate comprising:
- a base substrate that is at least partially bent;
- a connecting portion on the base substrate and connectible to a mounted circuit;
- and
- a first line and a second line at the base substrate and connected to the connecting portion;
- wherein
- the first line and the second line include:
- a first region in which the first line and the second line extend in parallel or substantially in parallel with each other;
- and
- a second region in which the first line and the second line extend in parallel or substantially in parallel with each other;
- and
- a maximum distance between the first line and the second line in the second region is smaller than a maximum distance between the first line and the second line in the first region.
