WebFor proper horn operation, it is preferred that the third horn 245 be transparent to the operating frequency bands of both the first horn 235 and the second horn 240. For example, the FSS of the third horn 245 can include FSS elements 255 which are reflective in the operational frequency band at which the third horn 245 operates, but pass ... Webof the horn antenna without the FSS and the filtenna system. Adding the FSS to the horn gives lower directivity at the passband by a figure of 3.6dB and that is due to the filtenna's wider beamwidth response. band.

WebAn integrated module with filtering and radiation performance realized by covering substrate integrated waveguide (SIW) cavity frequency selective surface (FSS) at aperture of horn antenna has been investigated in this paper. The module has functions of bandpass filter and horn antenna, so it is called a "filtering antenna" (filtenna). Web3D FSS is proposed based on square coaxial waveguides [9]. Nevertheless, it has a lot of building blocks, and its assembly is complex. In this Letter, a dual-band 3D FSS with high selectivity and small band ratio is proposed for dual polarisations.
