发明名称 Concentric set of microwave antennas
摘要 <p>Each ring is arranged in a location 25,26 of conductive material, with the quarter wave trap 28 fitted between the two locations. the quarter wave trap is limited on the one hand by the external wall of the location 25 of the closest antenna to the centre 14 and on the other hand by an internal wall 262 of the location 26 of the most distant antenna. these two walls are joined on a first side by a base and form an opening 29 issuing on the path of a leak current from the closest antenna to the centre. the external walls 25 of the location of the closest antenna to the centre 14 and those internal 262 of the location of the most distant antenna have an essentially cylindrical shape centred on the axis 12 of the assembly.</p>
