| Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a directional antenna particularly optimal for receiving radio waves of UHF bands, the directional antenna being configured to transmit and receive radio waves.SOLUTION: A directional antenna has: an H-shaped slit including a fundamental slit and an extension slit obtained by extending a full length of the fundamental slit; and a loop-shaped slit disposed around the H-shaped slit. Further, the fundamental slit and the extension slit are formed on the same conductor member. Accordingly, a structure is provided where the H-shaped slit is formed on the conductor member and the loop-shaped slit is disposed around the H-shaped slit, so that an antenna structure can be simplified. |
