Reconfigurable antenna system for e.g. ultra broadband application, has controller controlling connectors to pass from spiral antenna configuration to another configuration in which conductive elements form square spiral antenna array
The system (10) has a central reconfigurable area (20) including discrete conductive elements, and connectors for connecting or disconnecting adjacent conductive elements. A fixed area (30) includes continuous metal strands. A controller controls the connectors to pass from a configuration in which the elements form a spiral antenna to another configuration in which the elements form a square spiral antenna array, which is a part of a surface defined by a spiral antenna square surface, where the dimensions in the center of the square spiral antenna is the same regardless of the configuration. The connectors are selected from microelectromechnical system (MEMS), positive intrinsic negative (PIN) diodes, and field effect transistors. An independent claim is also included for a method for configuring an antenna system.
