摘要：A dual-band characteristic of single layer ‘I’ shaped rectangular microstrip slot antenna with differactedground is presented. It is a probe-fed- mechanism based antenna for matching impedance with 50Ω coaxial line. Theantenna geometry is simulated using IE3D software. Antenna works good in the frequency range 3.75 GHz to 4 GHz. Itis a light weight, low cost antenna, which can be used for wireless communication in UWB band. The antenna structureinvolves comparison of same antenna structure with three different heights. Final antenna geometry is designed with ‘I’slot on dielectric plane and diffracted ground plane, shows better improvement in the radiation characteristics. Also theeffects of slot implementation show the change in resonant frequency. MSA is with ‘I’ slot and diffracted ground plane,improves properties like resonance frequency, gain, return loss and bandwidth (substantially), which may affect theantenna performance. This structure uses single layer configuration; ‘I’ shape slot on the dielectric patch and finitediffracted ground plane. The antenna simulation yields -17 dB and -25.79 dB return loss at 4.034 GHz and 4.552 GHzresonant frequency with 7.31% and 9.42% bandwidth with a size of 18.375x39.7x1.5mm3. The proposed antennadesign presents a good choice for compact and low-cost microwave integrated systems.
