Abstract
An apparatus having multiple mushroom structures is disclosed. Each of the multiple mushroom structures includes: a ground plate; a first patch provided parallel to the ground plate with a separation of a distance to the ground plate; and a second patch provided parallel to the ground plate with a separation of another distance to the ground plate, which another distance being different from the distance from the first patch to the ground plate, wherein the second patch is a passive element which is capacitatively coupled with at least the first patch.

An apparatus having multiple mushroom structures, each of the multiple mushroom structures including:
- a ground plate;
- a first patch provided parallel to the ground plate with a separation of a distance to the ground plate;
- and
- a second patch provided parallel to the ground plate with a separation of another distance to the ground plate, which another distance being different from the distance from the first patch to the ground plate, wherein
- the second patch is a passive element which is capacitatively coupled with at least the first patch.
An apparatus having multiple mushroom structures of a first group and multiple mushroom structures of a second group, wherein
- each of the multiple mushroom structures of the first group includes:
- a ground plate;
- a first patch provided parallel to the ground plate with a separation of a distance to the ground plate;
- and
- a second patch provided parallel to the ground plate with a separation of another distance to the ground plate, which another distance being different from the distance from the first patch to the ground plate, wherein the second patch is a passive element which is capacitatively coupled with at least the first patch, and wherein each of the multiple mushroom structures of the second group includes:
- a ground plate;
- and
- a patch provided parallel to the ground plate with a separation of a distance to the ground plate, wherein a distance between a ground plate and a patch in a certain mushroom structure belonging to the second group is different from a distance between a ground plate and a patch in a different mushroom structure belonging to the second group.
An apparatus having multiple mushroom structures of a first group and multiple mushroom structures of a second group, wherein
- each of the multiple mushroom structures of the first group includes:
- a ground plate;
- a first patch provided parallel to the ground plate with a separation of a distance to the ground plate;
- and
- a second patch provided parallel to the ground plate with a separation of another distance to the ground plate, which another distance being different from the distance from the first patch to the ground plate;
- and
- the second patch is a passive element which capacitatively couples with at least the first patch, and each of the multiple mushroom structures of the second group includes
- a ground plate;
- and
- a patch provided parallel to the ground plate with a separation of a distance to the ground plate,
- wherein patches of neighboring mushroom structures mutually form a gap within the same plane, while patches of different neighboring mushroom structures are provided on mutually different planes with a positional relationship such that at lease some are laminated in multiple levels.
