Abstract
A one-wavelength loop antenna element (103) shaped like a rectangle is placed close to a radio base plate (101) and further is bent at both end parts toward a feeding section, whereby a current distribution where the current at the tip of turn up becomes zero is formed. Current is concentrated on the loop antenna element (103), so that the current component flowing onto the top of the radio base plate (101) is decreased, the effect produced when a human being carries a radio containing an antenna including the loop antenna element is suppressed, and the directivity responsive to an arrival wave is formed.
