In this paper, presents the grounding effect on the performance of UWB Ice Cream Cone Antenna communication. This planar antenna designed on a FR4 substrate with the dielectric thickness, 1.6 mm and the dielectric constant Ær, 4.7. An analysis results for antenna with different parameter for width of feed as a ground has been investigated. The antennas were designed and simulated by using CST Microwave Studio Simulation. The proposed antenna performs from 4 GHz to 11 GHz spectrum band. The return losses, S11 for the suggestion antenna must be below than -10dB and voltage standing wave ratio, VSWR less than 2. The best grounded single ice cream cone antenna performance was obtained at 5.688 GHz with antenna sizes is 12 mm x 14.5 mm. The antenna gives omnidirectional radiation characteristics from UWB spectrum band requirement with reasonable gain values.References
