- 論文の詳細を見る
The advantages of the use of directional antennas for portable telephones are demonstrated. They contribute to (1) reduction of power absorption into a head, (2) reduction of multi-path interference, and (3) power saving and increase of a battery life time. This paper compares directional and omni-directional antennas existing near the head of operator, in terms of radiation patterns with a head and the power absorbed into a head. It is pointed out that radiation patterns with a head are more or less directive for both types of antennas, while the power absorbed into a head is much smaller for directional antennas.
