In this paper, design and analysis of a compact printed monopole antenna with defected ground plane for\nwideband applications has been done. The proposed antenna has been designed on a FR4-epoxy substrate with dielectric\nconstant 4.4 and height is 1.6mm. In this proposed antenna design, the complimentary split ring resonators (CSRRs) are\netched from both patch as well as ground plane so as to work for wideband applications. The antenna has been fabricated\nwith optimized dimensions and then tested. The proposed antenna is fed by microstrip line feed and has been designed and\nsimulated by High Frequency Structure Simulator (HFSS version 13.0). The proposed antenna operates on S-band (2-4 GHz),\nC-band (4-8 GHz), X-band (8-12 GHz) and KU-band (12-18 GHz) applications. In the simulated results, the antenna design\noperates at four frequencies 2.7 GHz, 4.4 GHz, 6.6 GHz and 10.8 GHz with return losses of -18.39 dB, -13.79 dB, -17.10 dB\nand -22.82 dB. The gains at these four frequencies are 12.5 dB, 5.14 dB, 4.74 dB and 1.83 dB. In the measured results, the\nantenna design operates at four frequencies 2.6 GHz, 4.97 GHz, 6.13 GHz and 10.97 GHz with return losses of -18.10 dB,\n-25.80 dB, -23.10 dB and -17.30 dB.
