Abstract
A reflection unit of this disclosure is a reflection unit installed in a wireless transmission path between a first wireless device configured to at least transmit a wireless communication signal and a second wireless device configured to at least receive the wireless communication signal, in order to change a direction of the wireless transmission path. The reflection unit includes a plurality of reflectors configured to reflect the wireless communication signal. The plurality of reflectors include at least one reflectarray reflector.
Claims27
A reflection unit installed in a wireless transmission path between a first wireless device comprising a first antenna and being configured to at least transmit a wireless communication signal and a second wireless device comprising a second antenna and being configured to at least receive the wireless communication signal, in order to change a direction of the wireless transmission path,
- the reflection unit comprising
- a plurality of reflectors configured to reflect the wireless communication signal, wherein
- the plurality of reflectors includes a plurality of reflectarray reflectors,
- the plurality of reflectarray reflectors includes a first reflectarray reflector and a second reflectarray reflector,
- the first reflectarray reflector is configured to reflect a second reflected wave, caused by the second reflectarray reflector, of a second wireless communication signal transmitted from the second wireless device,
- the second reflectarray reflector is configured to reflect a first reflected wave, caused by the first reflectarray reflector, of a first wireless communication signal transmitted from the first wireless device,
- the first reflectarray reflector includes
- a first concentration reflection part configured such that the first reflected wave is concentrated at a focal point, and
- a first non-concentration reflection part configured such that the first reflected wave is not concentrated, and
- the second reflectarray reflector includes
- a second concentration reflection part configured such that the second reflected wave is concentrated at a focal point, and
- a second non-concentration reflection part configured such that the second reflected wave is not concentrated.
A reflection unit installed in a wireless transmission path between a first wireless device comprising a first antenna and being configured to at least transmit a wireless communication signal and a second wireless device comprising a second antenna and being configured to at least receive the wireless communication signal,
- the reflection unit comprising
- at least one concentration-type reflectarray reflector configured such that a reflected wave of the wireless communication signal is concentrated at a focal point, wherein the at least one concentration-type reflectarray reflector includes a first reflectarray reflector and a second reflectarray reflector,
- the first reflectarray reflector is configured to reflect a second reflected wave, caused by the second reflectarray reflector, of a second wireless communication signal transmitted from the second wireless device,
- the second reflectarray reflector is configured to reflect a first reflected wave, caused by the first reflectarray reflector, of a first wireless communication signal transmitted from the first wireless device,
- the first reflectarray reflector includes
- a first concentration reflection part configured such that the first reflected wave is concentrated at a focal point, and
- a first non-concentration reflection part configured such that the first reflected wave is not concentrated, and
- the second reflectarray reflector includes
- a second concentration reflection part configured such that the second reflected wave is concentrated at a focal point, and
- a second non-concentration reflection part configured such that the second reflected wave is not concentrated.
