Abstract
Around the world, wireless or distant communication has become fundamental and indispensable.Every day, billions of users access calls, the internet, and social media. Many electricalequipment, including the antenna, are used in the sophisticated networks and systems that supportthat massive information interchange. An electrical device known as an antenna sends or receivesinformation across space. The antenna is a key component in many systems, including radio andtelevision transmission, communications receivers, radar, cellular phones, Bluetooth-enabledgadgets, and satellite communications. The rapid expansion of wireless technology and personalcommunication has increased the demand for multiband antennas, which can operate at severalfrequencies and are suited for a variety of applications. Dual-band coplanar waveguide (CPW)fed rectangular microstrip patch antenna for 5G, WiMAX band, ISM Band, and WLAN applicationsis presented in this paper. The proposed antenna is robust, cheap, light weight, and easy tofabricate, resonating at 2.4 GHz in -12.182379 s11 with 205.7 MHz BW and 3.42 GHzin -37.344879 s11 with 464.9 MHz BW whereas gain is 3.85 and 3.41 respectively. Patch elementsare placed on isolation FR408 (loss-free) substrate of relative permittivity 3.75 kept at a substrateheight of 1.6 mm. Results of simulation are presented using CST STUDIO SUITE 2019.
