More Information
Summary:A coplanar waveguide (CPW) fed rectangular loop antenna with dual frequency characteristics applicable Wi-Fi bands is presented. The studies to calculate the dependency of frequencies on the antenna structure is carried out using ANSYS HFSS. From this, the antenna is optimized to have an enhanced gain of ∼ 8 dBi at 2.45 GHz and 3.83 dBi at 5.32 GHz. The radiation characteristics of the antenna are studied and the radiation pattern confirms the monopole characteristics at both the frequencies. The optimized antenna performance is confirmed by measurements using Vector Network Analyser. Since energized using coplanar waveguide the proposed antenna finds applications in Microwave Monolithic Integrated Circuits (MMIC) also.
