A dish antenna is provided as an antenna arrangement that reduces overall size, occupies a small amount of space, and shows an effect of high gain. The dish antenna includes a dish portion, a metal plate, a bracket, a carrier, a stand, and a bottom board. The dish portion shows a curved configuration. The metal plate carries at least one antenna element mounted thereto in a rectangular array, or in a left-right symmetric form, or simply set at a central position. The antenna elements are connected to each other with transmission match lines to realize concentration and in-phase superimposition of electromagnetic waves and increase of transmitting/receiving power of antenna. |
