Key result
A flexible meandered loop antenna operating at the MICS band demonstrated a sensitive resonant frequency shift corresponding to changes in heart model size, enabling remote cardiac monitoring.
A newly designed flexible meandered loop antenna operating at the MICS band can detect changes in heart size through resonant frequency shifts, offering potential for in-body cardiac monitoring.
May support remote cardiac monitoring in models; leaves open human validation before any clinical consideration.
In this paper, a meandered loop antenna, useful for medical cardiac monitoring application, more specifically, for heart beating close scrutiny is designed and experimentally tested. The proposed antenna is operating at the MICS band displays a high flexibility which allowing it to be curved easily around the heart's wall. In both, Simulation and measured results the antenna shows a sensitive nature any change introduced in heart's model size and would certainly bring about a noticeable shift in the antenna's resonant frequency. Linking the frequency variations taking place in concord with the heart movement turns out to stand as an effective key that provides extremely valuable information about the heart's activities. A correspondence between the obtained frequency variation linking with the change in size of the heart. In addition to the frequency response evaluation, the antenna characteristically displays an omni-directional radiation pattern, which necessarily fits it for in-body operation.
