Antenna design method and apparatus

摘要

An antenna design method executed by a computer includes creating an antenna model including an antenna which includes a plurality of antenna elements and matching circuits which are respectively connected to the plurality of antenna elements and which comprise a matching element including a parasitic reactance and a loss resistance; obtaining a characteristic of the antenna and a characteristic of the matching element; calculating a characteristic of the created antenna model using the obtained characteristic of the antenna and the characteristic of the matching element; judging whether or not the calculated characteristic of the antenna model satisfies a standard value; and displaying result of the judgment.

1. An antenna design method executed by a computer, the antenna design method comprising:
creating an antenna model including an antenna which includes a plurality of antenna elements and matching circuits which are respectively connected to the plurality of antenna elements and which includes a matching element including a parasitic reactance and a loss resistance; obtaining a characteristic of the antenna and a characteristic of the matching element; calculating a total efficiency of the antenna model using the obtained characteristic of the antenna and the obtained characteristic of the matching element, the total efficiency of the antenna model being a ratio of a total input power from a wave source to a radiation power from the antenna; judging whether or not the calculated total efficiency of the antenna model satisfies a desired total efficiency of the antenna; and displaying result of the judgment.
