Abstract In the current years, the interest in the growth of advanced wireless transfer systems for biomedical applications is rising significantly. Microstrip Patch Antennas (MPAs), as critical components, enable seamless data transfer within internal medical devices and external monitoring systems. However, MPAs used in biomedical applications often face limitations such as limited multi-band operability and inefficient power transfer, which hinders their performance in complex biomedical environments. This research work presents the suggested MPA, meticulously engineered to resonate efficiently across 0. 403, 0.915, 1.4 and 2.45 GHz. The design process involves iterative optimization to achieve low return loss, stable radiation patterns, voltage standing wave ratio, and high gain. It also achieves a Avg specific absorption rate of 1.9590, 1.9970, 1.8236, and 1.6954 W/kg for all he four operational frequencies of the presented QBMPA in 10 g tissues. Complementing the antenna is the presented rectifier, achieving minimal power reflection and maximum energy conversion efficiency. The rectifier reaches up to approximately 60 % for 10 dBm power. Together, the multiband antenna and rectifier form a efficient and robust system for Wireless Power Transfer (WPT), enhancing the functionality and reliability of implantable medical devices.
