| 摘要 |
The invention relates to a method for the electromagnetic decoupling of a substantially vertical support pole (1) made of en electrically conductive material and an antenna (2) which emits, in a frequency band centred on a central frequency, waves having an at least partially vertical polarisation, and which is supported by said supporting pole (1), characterised in that said antenna (2) is mounted on said pole (1) by a connection arm (4) and in that at least two electromagnetic decoupling devices (3) are arranged on the supporting pole (1) between the antenna (2) and the pole (1), including at least one decoupling element (17) conducting electromagnetic waves having a wavelength that is one fifth to one third of the wavelength of the waves emitted by the antenna (2) at the central frequency, at least a first device (3) being arranged on the pole (1) above said connection arm (4) and at least a second device (3) being arranged on the pole (1) below said connection arm (4), so as to neutralise the currents induced in the pole (1) by the waves emitted by said antenna (2). |
