The article delves into the concepts of return loss and Voltage Standing Wave Ratio (VSWR), highlighting their critical roles in antenna performance. It explains that RF energy, akin to sound, can reflect back when transmitted through coax cables or PCB traces, which must be minimized for optimal antenna operation. Return loss quantifies the amount of RF energy reflected back, with higher values indicating superior performance, as they reflect greater energy absorption by the antenna. VSWR pr
