ANTENNA DEVICE

Disclosed is an antenna device, comprising a fixing rod, fixing the antenna device into a destination by means of one end of the fixing rod; a transmitting antenna, provided on the other end of the fixing rod and configured to transmit a signal; and a plurality of supporting arms, one end of each supporting arm being fixed into the fixing rod so that the plurality of supporting arms is provided around the fixing rod as the center, and the other end of each supporting arm being configured to receive an antenna. The plurality of supporting arm is unfolded or folded with respect to the fixing rod, so that the receiving coverage of a receiving antenna is expanded, and gain of imbalance between the signal transmitted by the transmitting antenna and the signal received by the receiving antenna in a wireless communication system is realized. L'invention concerne un dispositif d'antenne, comprenant une tige de fixation, fixant le dispositif d'antenne dans une destination au moyen d'une extrémité de la tige de fixatio
