Filter including a microstrip antenna and a frequency selective surface

A filter, comprising:

• an enclosure;
• a dielectric material, within said enclosure;
• at least two microstrip antennas, within said enclosure;
• and
• at least one frequency selective surface, including a metallic pattern, within said enclosure and encapsulated by said dielectric material;
• wherein said at least one frequency selective surface is embedded in said dielectric material;
• wherein said enclosure encapsulates said at least one frequency selective surface;
• wherein said at least one frequency selective surface filters an electromagnetic signal propagated within said enclosure,
• wherein the electromagnetic signal is a microwave or millimeter wave signal,
• wherein each of said at least two microstrip antennas and each of said at least one frequency selective surfaces are arranged in substantially parallel planes.

A filter, comprising:

• an enclosure;
• a dielectric material, within said enclosure;
• at least two microstrip antennas, within said enclosure;
• and
• at least one frequency selective surface, including a metallic pattern, within said enclosure and encapsulated by said dielectric material;
• wherein said at least one frequency selective surface is embedded in said dielectric material;
• wherein said enclosure encapsulates said at least one frequency selective surface;
• wherein said at least one frequency selective surface filters an electromagnetic signal propagated within said enclosure,
• wherein the metallic pattern on each of said at least one frequency selective surfaces reflects at least one frequency,
• wherein said at least two microstrip antennas includes two microstrip antennas, separated by a divider, one acting as a transmitter of several frequencies along a signal path and the other acting as a receiver of a specific frequency band;
• wherein said at least one frequency selective surface includes two frequency selective surfaces, arranged at an acute angle to the signal path, one of the frequency selective surfaces receiving the several frequencies from the transmitter and reflecting the specific frequency band, along with the second frequency selective surface, to the receiver.
