Definitions
- the present invention relates to an antenna structure.
- an antenna structure as described in Patent Document 1 has been adopted for transmitting and receiving electric signals.
- Such an antenna structure has, for example, a structure in which an electric filter substrate is laminated on the upper surface of a control board (RF control board) and an antenna substrate is laminated on the upper surface of the electric filter substrate.
- the antenna substrate and the control substrate are connected via an electric filter substrate. Therefore, the wiring becomes long and the transmission loss becomes large. Further, since such an antenna structure has a laminated structure, the antenna substrate, the electric filter substrate, and the control substrate cannot be reused when a connection failure occurs. As a result, the yield is low. In order to avoid such defects, relatively expensive low-dielectric materials and low-loss materials are used, which leads to an increase in cost.
- the antenna substrate, the electric filter substrate, and the control substrate have substantially the same size. Since such an antenna structure has a laminated structure, it is not possible to apply each member in an arbitrary size according to the arrangement location. As a result, it is difficult to reduce the size of the antenna structure.
- the antenna structure according to the present disclosure includes an antenna substrate having a first surface and a second surface located opposite to the first surface, a transmissive filter located on the first surface, and a control board located on the second surface.
- the first annular pattern is located on the surface facing the first surface
- the second annular pattern is located on the opposite surface to the facing surface
- the first annular pattern and the second annular pattern are viewed through a plane. It is located on top of each other.

- the conventional antenna structure has a structure in which an electric filter substrate is laminated on the upper surface of a control board (RF control board) and an antenna substrate is laminated on the upper surface of the electric filter board. Therefore, as described above, the yield may be low, the cost may be increased, or each member may not be applied in an arbitrary size according to the placement location.
