The antenna has an adaptation element formed of a conductor element (204) and a voltage-variable capacitor (205), for adapting input impedance of the antenna, and a metal plate provided with a power supply zone or point (103). The adaptation element is arranged in direct electric contact with a ground plane (101) and with a radiating element (100) e.g. meander or spiral monopole. The adaptation element realizes capacitive impedance adaptation if the antenna is inductive type antenna, or inductive impedance adaptation if the antenna is capacitive type antenna. |
