ANTENNA FOR TRANSMISSION / RECEPTION OF RADIO FREQUENCY / WAVES AND AN AIRCRAFT USING SUCH AN ANTENNA

摘要

This invention relates to an antenna for transmission / reception of radio frequency waves that comprises: - a structural element (8) that is conducting in the operating frequency band of the antenna, with size equal to at least one quarter of the wave length along the polarization direction of the electromagnetic wave for the minimum frequency of this frequency band, and comprises a cutout forming a cavity (9). - a removable exciting element (10) placed in this cavity that acts as an exciter of this cavity (9), - a metallization that is electrically conducting at the operating frequencies of the antenna providing metallization between the said exciting element (10) and the said structural element (8). This invention also relates to an aircraft using such an antenna.
