Rollable antenna mat

A rollable antenna mat for sports timing comprising:

• a plurality of planar ultra-high frequency antenna structures connected to ultra-high frequency coaxial transmission lines configured to convey signals to and/or from the planar ultra-high frequency antenna structures;
• each of the planar ultra-high frequency antenna structures comprising at least one conductive plate positioned above a conductive ground plane, a spacer element positioned between the conductive ground plane and the conductive plate, each planar ultra-high frequency antenna structure being configured to generate a radiation field, the radiation field having a main axis that is substantially perpendicular to the conductive plate;
• and,
• the plurality of planar ultra-high frequency antenna structures and ultra-high frequency coaxial transmission lines being embedded in a flexible elongated sheet structure of one or more elastomeric materials, the flexible elongated sheet structure comprising the plurality of planar ultra-high frequency antenna structures and ultra-high frequency coaxial transmission lines being configured to be rolled up in a roll, an axis of the roll being substantially perpendicular to a longitudinal axis of the flexible elongated sheet structure.
