Antenna design method and apparatus
First Claim
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.
