Wideband characteristics of Modified Elliptical Monopole Antenna Fed with CPW for Wideband Applications
In this paper, modified elliptical antenna is designed on FR - 4 epoxy substrate material having dielectric constant 4.4 and its loss tangent 0.02 is proposed for wideband applications. Conventional elliptical patch antenna with Co-planar waveguide (CPW) feed attains Ultra - wide band (UWB) characteristics ranging from 5.70 - 13.96GHz to cover C - & X - band applications. Elliptical geometry can be modified into rings shape to obtain impedance bandwidth (IBW) 1.32GHz and 1.18GHz at dual resonances 6.44GHz and 9.04GHz. In order to enhance the wideband by employing concentric ring inside the elliptic structure in addition by loading stubs. This proposed design achieves tri-wide band characteristics having impedance bandwidths 460MHz (3.83-4.29GHz), 1.83GHz (4.62-6.45GHz), 9.03GHz (7.45-16.5GHz) respectively at 4.05GHz, 5.96GHz and 14.42GHz. The proposed antenna has unique and omni -directional radiation characteristics with negligible side lobes. The proposed antenna overs C - band (WiMax, WLAN), X - band (Satellite and radar communication) and Ku-band such as weather and ship radars applications.
