Method for producing an antenna, operating in a given frequency band, from a dual-band antenna

摘要

The present invention relates to a method for producing an antenna operating in a given frequency band, from a dual-band antenna. According to the method, the dual-band antenna is a broadband slot antenna that receives and/or transmits electromagnetic signals at a first frequency and at a second higher frequency. The antenna is powered by a single power supply line, and the free end of the power supply line is connected, by a connection means that can be opened or closed, to at least one means for rejecting one of the frequencies. This invention can be used in producing generic electronic boards.

1. Method for implementing an antenna operating in a given band of frequencies using a wideband antenna, the method comprising
providing a slot type wideband antenna for receiving and/or transmitting electromagnetic signals within a wide frequency band, the antenna comprising a power supply line having one free end, a rejection line for rejecting frequencies included in said wide frequency band and a connector inserted between the free end of the power supply line and the rejection line, and switching the connector between a closed state providing a short circuit between the rejection line and the power supply line to enable the antenna to reject the frequencies included in said wide frequency band and an open state in which the rejection line is not connected to the power supply line enabling the antenna to operate as a dual band antenna.
