The parametric study of Side Fed Bifilar Helix Antenna (SFBHA) is reported for varying height and varying sized finite metallic ground planes for L-Band communications. The radiation characteristics like 3dB power beamwidth and boresight axial ratio are enhanced when SFBHA is deployed over smaller ground planes. Also, increase in height of the SFBHA above these ground planes plays a supportive role...
An ultra-wideband antenna has been proposed in this paper, which rejects WLAN bands to suppress the interference. Dual notch is achieved at the upper and lower WLAN bands by removing U and inverted-L slot. By varying the parameters of slots desired rejected band and notch position is achieved. The proposed antenna size is 30x30 mm2 is fed by 50 ohm micro strip transmission line. Partial ground plane...
