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.
