【 摘 要 】

A hybrid dual-band antenna, consisting of an L-shaped radiating slot and a cylindrical dielectric resonator antenna (CDRA) is proposed, simulated and experimentally validated in this paper. The microstrip transmission line excites the fundamental mode (TM₁₀) of the slot that generates the lower frequency resonant band (2.4 GHz) and slot below the CDRA excites HEM₁₁ mode of the CDRA to generate higher frequency band (5.8 GHz). The slot and CDRA modes are quasi-independent of each other and the resonant frequency of both modes can be adjusted quasi-independently. An equivalent circuit model of the independent modes and hybrid system is extracted to show the real behaviour of the modes and overall system. The on-body analysis of the antenna shows that the antenna is suitable for use in wearable biomedical devices.
