In this paper, card antennas with simple structure are focused and the bandwidth characteristics to clarify the limitation of downsizing are examined. Effects of an aspect ratio of antenna shape, a location of feeding point and characteristic impedance on the bandwidth characteristics are discussed. Furthermore, limitation of downsizing is examined in the view point of lower frequency of the frequency band.
