| 摘要 |
The present invention relates to a device (30) for transmitting and/or receiving radio frequency signals comprising at least one antenna (31) and/or at least one filter (32a, 32b) realized in a printed technology on a dielectric substrate. According to the invention, this device is equipped with a means for compensating the permittivity dispersion of the substrate. For said purpose, the device comprises a circuit (10) for measuring the dielectric permittivity of the substrate which is able to deliver a measured permittivity value and adjustment means (20, 36) which are able to adjust the impedance of the antenna and/or the frequency response of said filter according to said measured permittivity value. |
