Abstract
An antenna device comprising a hollow dielectric plastic holder (17) with a pair of opposite ends. A first helical electrode plate (18) is attached to one of the pair of opposite ends and has a first terminal device (25). A second flat electrode plate (19) is attached to the other of the pair of opposite ends and has a second terminal device (28).
Claims9
An antenna device comprising:
- a hollow dielectric plastic holder with a pair of opposite ends with the hollow inside of the holder open to the air through the pair of ends:
- a first helical electrode plate attached to one of the pair of opposite ends, the first electrode plate having a first terminal device;
- and
- a second flat electrode plate attached to the other of the pair of opposite ends so as to be opposite the first electrode plate, the second electrode having a second terminal device.

An antenna device comprising:
- a dielectric plastic holder with an upper and a lower surface;
- a first electrode plate with a first terminal device attached to the upper surface of the holder;
- and
- a second electrode plate with a second terminal device attached to the lower surface of the holder so as to be opposite the first electrode plate;
- the first and second terminal devices being disposed side by side at a side of the holder and having end portions connected to a circuit board.
2 more elements
A method of making an antenna device comprising the steps of:
- forming a first helical electrode plate with a first terminal device;
- disposing the first electrode plate with the first terminal device at a predetermined position in a mold;
- injecting a dielectric resin into the mold, thereby forming a hollow holder integral with the first electrode;
- taking out the hollow holder integral with the first electrode from the mold;
- and
- fixing a second electrode plate with a second terminal device to the taken out holder so as to be opposite to the first electrode plate.
