Abstract
A communications device includes: an antenna radiating a first radio wave having a first polarization direction and a second radio wave having a second polarization direction, the first and second polarization directions being different; a casing provided with an opening through which the first radio wave and the second radio wave pass; and a cover provided to the opening and including a plurality of bars made of metal. The antenna is disposed so that neither the first polarization direction of the first radio wave nor the second polarization direction of the second wave orthogonally intersects with an extending direction of the bars.

A communications device, comprising:
- an antenna configured to radiate a first radio wave having a first polarization direction and a second radio wave having a second polarization direction, the first and second polarization directions being different;
- a casing provided with an opening through which the first radio wave and the second radio wave pass;
- and
- a cover provided to the opening and including a plurality of bars made of metal,
- the antenna being disposed so that neither the first polarization direction of the first radio wave nor the second polarization direction of the second wave orthogonally intersects with an extending direction of the bars.
A communications device, comprising:
- an antenna configured to radiate a first radio wave having a first polarization direction and a second radio wave having a second polarization direction, the first and second polarization directions being different;
- a casing provided with an opening through which the first radio wave and the second radio wave pass;
- and
- a cover provided to the opening and including a space shaped into an X-shape, the space being formed in a region corresponding to (i) the radiating element, and (ii) each of:
- a region extending, in the first polarization direction, forward and backward from the radiating element over a predetermined range;
- and a region extending, in the second polarization direction, forward and backward from the radiating element over a predetermined range.
