A meandered rectangular monopole antenna for quad-band applications

This paper presents the design of a quad-band meandered monopole antenna for wireless applications. The design reports a compact antenna with dimension 25*16 mm2 having microstrip feed. The quad-band resonance is obtained by proper meandering of the patch and ground plane. The impedance bandwidth of the designed antenna is 70 MHz for 2.1 GHz CDMA, 40 MHz for 3.53 GHz WiMAX IEEE 802.16, 40 MHz for 4.3 GHz wireless avionics intra-communication, and 6600 MHz for the upper UWB range from 5 GHz to 11.6 GHz. The simulation results match well with the measurements and hence validate the proposed design technique.
