Configurable dual mode antenna system
A method for suppressing feedline interference in array applications uses a frequency selective surface (FSS). A Fabry-Perot Cavity (FPC) antenna with an integrated fluidic channel alters the FSS structure of the antenna and minimizes radiation from feedlines in antenna arrays and three dimensional (3D) packaging designs. The technology results either in beam-splitting or beam-focusing (with respect to near- and far-field performance of the antenna system), and the fluidic channel may be filled with air or deionized (DI) water. When the channel is filled with deionized water, the antenna system operates in beam-splitting mode, and when the channel is filled with air, it operates in beam-focusing mode. The configurable antenna system can switch from one mode to the other.

Solves feedline interference and coupling
Demand for ubiquitous access to multiple radio terminals in wireless communication has been growing. As a result, reconfigurable radio platforms are being developed and advanced to address this need. Fabry-Perot Cavity (FPC) antenna systems offer the ability to beam form a source signal, but the energy focusing of weak feedline radiation through the FSS can lead to FPC system radiation pattern degradation. This feedline interference and coupling can degrade array and 3D high density packaging performance. This new method, by simply locally augmenting a frequency selective surface (FSS), reduces the feedline’s impact on the overall antenna performance in general and solves feedline interference and coupling in array and 3D high density packaging.
