1. A dual band printed antenna comprising:

  • a substrate comprising a first surface and a second surface opposite to each other and at least two electrically conductive holes penetrating therethrough;

    a first driver disposed on the first surface and configured to generate a first radiation pattern of a first frequency band;

    a first reflector disposed on the first surface and apart from the first driver at a first distance;

    a second driver disposed on the second surface and configured to generate a second radiation pattern of a second frequency band, wherein the second driver is electrically coupled to the first driver through the at least two electrically conductive holes;

    a second reflector disposed on the second surface corresponding to the position of the first driver and apart from the second driver by a second distance; and

    a transmission line disposed on the first surface and electrically coupled to a feed point and a ground point of the first driver.
