A low height, space efficient, dual band monopole antenna is provided. The antenna includes a first conductive post, a second conductive post and a third conductive post extending between a lower oblong shaped PCB and an upper oblong shaped PCB. A signal is applied to a bottom end of a first conductive post and bottom ends of the remaining two posts are coupled to ground. The top of the first post is connected to the tops of the second and third posts by a serpentine trace which in one embodiment is symmetric and in another embodiment is asymmetric. The asymmetric embodiment achieves improved dual band operation without the need for an impedance matching network.
