Abstract (en)

A slot antenna with a filter network is provided. The slot antenna is connectable to an antenna feed, and configured to resonate at a first frequency when surface current from the antenna feed flows around the slot antenna, the slot antenna comprising a first side and a second side separated by a width. A filter network bridges the first side and the second side, across the width, at a given position from a surface-current-originating end of slot antenna, the filter network configured to: electrically isolate the first side from the second side at the first frequency so that a length of the slot antenna defines a resonant length of the slot antenna at the first frequency; and, electrically connect the first side to the second side at a second frequency higher than the first frequency, so that the surface current flows across the filter network at the given position.
