Ref. | Frequency (GHz) | Rectenna turn-ON power density | Rectenna angular coverage (°) | Flexible |
|---|---|---|---|---|
24 | 5 dBm cm−2 at \(R_L = {739}\,{\Omega }\) | 40 | YES | |
24 | − 3 dBm cm−2 at \(R_L = {160}\,{\Omega }\) | 40 | NO | |
20.2 | − 3 dBm cm−2 at \(R_L = {300}\,{\Omega }\) | 40 | NO | |
28 | − 6 dBm cm−2 at \(R_L\) = 1 \(\hbox {k}\Omega\) | 85 | NO | |
This work | 28 | − 6 dBm cm−2 at \(R_L\) = 1 \(\hbox {k}\Omega\) | 110 | YES |
