<P>PROBLEM TO BE SOLVED: To provide a wireless LAN antenna, control method for the wireless LAN antenna, antenna for a wireless LAN base station, antenna for wireless LAN mobile station terminal, wireless LAN card for a terminal and wireless LAN system in which a communicable area of a wireless LAN mobile station is not restricted and further a plurality of network groups can be spatially formed. <P>SOLUTION: The wireless LAN antenna to be used for the wireless LAN system for mutually transmitting a high frequency radio wave for the wireless LAN system between the wireless LAN base station and the wireless LAN mobile station is composed of a high frequency line including a high frequency microstrip line structure 1a resulting from successively stacking a dielectric layer 2 and a signal line 4 on a ground layer 3, and a plurality of circular polarizing antenna elements 6a, 6b which are disposed on the high frequency line and have different turning directions. The plurality of circular polarizing antenna elements 6a, 6b having different turning directions are disposed on the high frequency line 1a by leaving a space from each other. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
