Horn antenna i.e. double bridge horn antenna, for high frequency sensor and signal transfer applications in e.g. environment, has side walls comprising periodic conductor strip structure, and connected together by connecting lead

摘要

The antenna has side walls comprising a periodic conductor strip structure, and connected together by a connecting lead. Parts of the side walls are completely removed from lighting strips, and the periodic conductor strip structure comprises recesses, where the recesses are bridged suitable high frequency. The conductor strips lie one below the other, and are connected together with suitable high frequency capacitors. Sections of a conductor surface are covered with the capacitors. Electrical conducting parts of the antenna consist of thin metallization. The thin metallization is attached on non-conducting plastic molding parts.
