In this paper, a novel triple band (f1, f2, f3) antenna for Universal Serial Bus (USB) dongle applications is proposed. The proposed antenna is made up a monopole antenna along with top and bottom parasitic resonators. f1 is obtained by the whole length of the antenna. The monopole antenna acts as the main radiator for f3 and also as the coupling feeding structure for the parasitic resonators in f1, f2. The f2 resonance is obtained by connecting the top and bottom parasitic resonators through a via. The 10dB reflection coefficient bandwidth of the proposed antenna is compatible with the WLAN (2400-2485 & 5150-5850 MHz) and WiMAX (3400-3600 MHz) bands.
