Performance Analysis of Slotted Microstrip Antenna with Variant Substrates

In this paper, a simple double-side slot rectangular microstrip patch (DSS-RP) antenna is presented. The antenna is used for multi-band purposes and the operating frequency ranges from 2 to 4GHz. In this design, five different substrates (BAKELITE, RT DUROID, FR-4, TACONIC, and RO4003) have been analysed for the proposed antenna design. The comparison performance is analysed based on the Reflection coefficient, VSWR, Axial ratio and appropriate gain characteristics within the frequency range. This slotted antenna design structure improves the dual-band responses for wireless communication. The slot insertion on the radiating element will provide the appropriate gain characteristics (>1.5dBi) and promote the enlargement of the bandwidth.
