Design of an Ultra- Wideband Antenna for Ambient Radio Frequency Energy Harvesting in 10.88-33.66 GHz

This paper aims at exploiting the expected massive deployment of RF signals by proposing a low-cost ultrawideband (UWB) planar antenna with a bandwidth of approximately 23 GHz ranging from 10.9 to more than 33.66 GHz. Using different slots on the patch and ground planes and through feedline transitions the UWB requirements are achieved. Simulation results show that a proposed antenna with optimized dimensions can enhance the impedance matching and increase the bandwidth with minor effects on the antenna performance. The antenna is fabricated, and the simulated results are validated by the experimental measurements.
