In each design variant, the RF energy is coupled and launched through microstrip antennas. These antennas are highly directive and have high gain value. Impedance matching and mode matching between the MS line and RWG are achieved by multi-step impedance transformer and inset feeding of antenna.
In all four designs a microstrip patch antenna is used for RF energy launcher. Four microstrip-to-rectangular waveguide (MS-to-RWG) transitions for next-generation mm-wave communications are designed for D-band at operating frequency 140 GHz.
The RF energy harvesting performance of the stretchable microstrip antenna was measured by connecting it with a commercial RF energy harvesting evaluation kit (AEM30940 2.45 GHz EVK, e-peas). The same RF module used in wireless communication was explored to transmit the RF energy at a power of 7 dBm.
The 3D microstrip antennas with strain-insensitive resonance, improved stretchability, and enhanced peak gain are highly promising for use in on-body wireless communication and RF energy harvesting.
