Summary:
Helmet antennas have been widely developed as wearable antennas for military and disaster prevention uses. To reduce the operational frequency band and overcome the gain reduction in proximity to human head, this paper presents the inverted-F antenna on the hemispherical metal ground plane. The arrangement of the antenna element and the feeding directions are examined in detail through electromagnetic simulation. As a result, the gain of ?3.0 dBi is achieved in proximity to the human head.
