Microstrip arrangement

An antenna arrangement comprising:

• a first ground plane;
• a second ground plane separated from the first ground plane by at least a first and a second dielectric material, the second ground plane being substantially parallel to the first ground plane and having at least one opening;
• a first microstrip conductor substantially parallel to the first and second ground planes and having substantially the same dimensions in the longitudinal and transverse directions as the at least one opening in the second ground plane;
• a second microstrip conductor separated from the first microstrip conductor by at least a portion of the first dielectric material and galvanically coupled to the first microstrip conductor by at least one connector, the second microstrip conductor having substantially the same dimensions in the longitudinal and transverse directions as the first microstrip conductor and being substantially parallel to the first microstrip conductor;
• and
• at least one radiating device, separated from the second ground plane by a third dielectric material;
• wherein the first and second microstrip conductors and the at least one connector form a microstrip arrangement separated from each of the ground planes by the second dielectric material, the first and second microstrip conductors being substantially aligned with the at least one opening of the second ground plane in a direction perpendicular to the conductors, such that energy radiated from the microstrip arrangement is electro-magnetically coupled to the at least one radiating device.
