A pad includes a first mating section and a second mating section. The first mating section includes a first horizontal plane and a first inclined plane. The second mating section includes a second horizontal plane and a second inclined plane. The first mating section is a copper foil capable of being connected to a wire. The second mating section is made of insulating material. The first inclined plane and the second inclined plane are bonded together.
1. A pad, comprising: a first mating section connecting to a wire and including a first horizontal plane and a first inclined plane inclined inwardly relative to the first horizontal plane wherein the first horizontal plane is a first proiected plane of the first inclined plane and wherein the first mating section is a copper foil; and a second mating section including a second horizontal plane and a second inclined plane inclined relative to the second horizontal plane, wherein the second mating section is made of insulating material, the first inclined plane is opposite to the second inclined plane.
2. The pad of claim 1 , wherein an included angle between the first horizontal plane and the first inclined plane is substantially 45 degrees.
3. The pad of claim 1 , wherein the first inclined plane is substantially parallel to the second inclined plane.
4. The pad of claim 3 , wherein the first inclined plane and the second inclined plane are flat surfaces opposite to each other.
5. The pad of claim 1 , wherein the first inclined plane and the second inclined plane are bonded together.
6. The pad of claim 1 , wherein the first horizontal plane is substantially parallel to the second horizontal plane.
7. The pad of claim 1 , wherein the first mating section and the second mating section jointly form a pillar.
8. The pad of claim 7 , wherein the pillar is a cylinder.
9. The pad of claim 1 , wherein the first mating section is laterally connected to the wire.
10. The pad of claim 1 , wherein the first inclined plane inclined relative to the first horizontal plane reflects a signal received from the first mating section, and an incident direction and a reflective direction of the signal are on separate lines.
11. The pad of claim 1 , wherein the first mating section is a half of a cylinder, and the second mating section is the other half of the cylinder.
