Japanese Patent JP2001523414
Kind Code:
A
Abstract:
The disclosure relates to an antenna. To improve transmission and reception in a mobile telephone, it has what is termed a diversity antenna. The invention relates to an antenna suitable as a diversity antenna. The antenna has a plate of insulating material with a foil coating on both sides. In the foil there are provided two slots, one on each side. The slots have meander formations or windings in order that their electric length exceed their physical length. The one slot is 1-3 % longer than the other. At one closed end of the one slot, there are connections for a supply line. The foil coatings are in contact with one another through a plate which is soldered fast on the side of the carrier at right angles thereto. Laterally in relation to the longitudinal direction of the slots, there is an earth plane. The foil coatings extend out on this, and both sides are in galvanic communication with one another. In order to increase the electric length of the earth plane, slots are provided in the foil coatings.
