Abstract
Disclosed is a multi-band plasma loop antenna that may reduce radio interference and provide multiple bands. First, the multi-band plasma loop antenna includes an antenna element including a plurality of plasma loop patterns; a plasma activation controller configured to activate a specific plasma loop pattern among the plurality of plasma loop patterns based on an input signal; and at least one RF feed configured to apply an RF signal to the antenna element. Accordingly, a selective multi-frequency band antenna may be easily implemented, and interference between loops may be minimized. In addition, antenna radiation efficiency may be increased by taking a stacked structure.
