In this research, an active antenna operated at the second harmonic frequency is investigated, and is implemented using microstrip antenna material.The antenna consists of a FET oscillator which plays as a fundamental frequency oscillator and a frequency multiplier, and a patch antenna resonated at the Lamps second harmonic frequency as the radiato
Abstract Foodborne diseases are a major challenge in the global food industry, especially those caused by multidrug-resistant (MDR) bacteria.Bacteria capable of biofilm formation, in addition to MDR strains, reduce the treatment efficacy, posing a significant threat to bacterial control.Bacteriophages, which are viruses that infect and kill bacteri
