Abstract :
This paper presents the design of a low profile dual-band (on- / off-body modes) planar antenna in meandered shape with microstrip line feed for biomedical applications. The antenna is designed to operate in the ZigBee dual band 868-928 MHz and 2.4-2.5 GHz respectively. While the proposed antenna is simulated on direct surface of human skin model, it shows a good performance with the broad bandwidth for |S11| less than -10 dB. The antenna is designed with 50 Ω input port and on LTCC substrate (εr = 7.1, tanδ = 0.005) with miniaturized volume of 16.5 mm × 17 mm × 0.8 mm.
