As shown in Fig. 2, the antenna is printed on FR4 substrate and fed with a 50 Ω coplanar feed line. The simulation results show that embedding the slot and the slits in the triangular resonator increase the upper frequency bound resulting in a total bandwidth of 8.3 GHz.The overall bandwidth increased by almost 1.1 GHz and the return loss (S 1,1) has decreased substantially compared to the ... Bandwidth enhancement and size reduction of an implantable ... By means of embedding hook‐shaped slots at the edges of the radiating patches for a stacked planar inverted‐F antenna (PIFA), functions of bandwidth enhancement and size reduction can be achieved for suitable use in implantable biotelemetry devices. Bandwidth Enhancement and Size Reduction of Microstrip ...
