Design Of Wideband U Slot Microstrip Antenna
In this paper, the authors design a wideband rectangular micro strip antenna for covering wireless mobile applications. The proposed antenna geometry describes a coaxial fed rectangular patch printed over a FR4 substrate of thickness 1.6mm and permittivity 4.4.The design parameters for the antenna are length and width of the patch and slot. Broadening the antenna bandwidth is achieved by U-slot technique. The antenna analysis is carried out with full wave simulation Ansoft HFSS by using the parameters return loss (dB), bandwidth, VSWR, radiation pattern and gain. The antenna operating frequency range is 1.85GHz - 2.49GHz with VSWR less than 2.
