1. An antenna comprising:
a substrate; and
a first conductor part and a second conductor part formed on the substrate, wherein
the first conductor part has a first sleeve and is connected to a signal wire,
the second conductor part has a second sleeve and is connected to a ground wire, and
the first conductor part and the second conductor part operate as a sleeve dipole antenna,
wherein
the substrate has a first side and a second side opposite to the first side,
the first conductor part has a first portion on the first side of the substrate and a second portion on the second side of the substrate, the first portion of the first conductor part being connected to the second portion of the first conductor part via one or more first connections through the substrate,
the second conductor part has a first portion on the first side of the substrate and a second portion on the second side of the substrate, the first portion of the second conductor part being connected to the second portion of the second conductor part via one or more second connections through the substrate, and
the second portion of the first conductor part has a first predetermined shape and the second portion of the second conductor part has a second predetermined shape, wherein outer portions of the first and second predetermined shapes are mirror images of each other.
