The proposal is for a compact and novel shaped frequency-reconfigurable Monopole antenna with a large tuning band. Depending on the switching states, the recommended antenna works in single band modes. In the modelling context, lumped components are utilised to offer variable capacitance, which is responsible for frequency settings. The built antenna’s tuning capacity has been discovered to be between 2.1 and 5.2 GHz. For all resonant bands, the proposed antenna has a VSWR of 1.3. The High Frequency Structure Simulator is used to test the proposed antenna’s far field and scattering characteristics (HFSS). The developed antenna may be readily integrated into modern communication devices such as smart phones, laptops, and other portable electronic equipment due to its small size and inexpensive cost. To verify the simulation findings, a model of the proposed antenna is created and monitored using PIN diode switches. The measured and anticipated results for the recommended reconfigurable antenna are satisfactory.
