Antena pembetulan adalah salah satu komponen terpenting untuk aplikasi penghantaran kuasa tanpa wayar. Dalam kertas kerja kami sebelum ini, beberapa litar penukaran RF-DC dengan kecekapan penukaran tinggi pada kuasa input rendah dicadangkan. Walau bagaimanapun, litar penukaran RF-DC ini mempunyai beberapa bahagian yang saiznya bergantung pada kekerapan operasi, jadi saiz litar menjadi besar pada frekuensi operasi yang rendah. Dan, komposisi litar penukaran RF-DC ini adalah rumit. Oleh itu, dalam kertas ini, litar penukaran RF-DC baharu yang terdiri daripada peranti cip sahaja dicadangkan. Litar ini mempunyai kecekapan penukaran yang lebih tinggi daripada litar yang dicadangkan sebelum ini. Dan, pengurangan saiz litar penukaran RF-DC direalisasikan. Selain itu, komposisi litar adalah mudah, jadi saiz litar tidak bergantung pada kekerapan operasi. Untuk reka bentuk litar penukaran RF-DC, kaedah LE-FDTD digunakan. Keputusan pengukuran bersetuju dengan keputusan analisis kaedah LE-FDTD dengan sangat baik, dan ketersediaan kaedah LE-FDTD ditemui. Ia ditunjukkan bahawa kaedah LE-FDTD adalah cara analitik yang berkuasa yang boleh memberikan reka bentuk litar penukaran RF-DC yang cekap dengan kecekapan penukaran yang tinggi.

Abstract: A rectifying antenna is one of the most important components for wireless power transmission applications. In our previous papers, some RF-DC conversion circuits with high conversion efficiency at low input power are proposed. However, these RF-DC conversion circuits have some parts of which size depends on operating frequency, so the circuit size becomes large at low operating frequency. And, the composition of these RF-DC conversion circuits is complicated. Therefore, in this paper, a new RF-DC conversion circuit composed of only chip devices is proposed. This circuit has higher conversion efficiency than the previously proposed circuits. And, size reduction of the RF-DC conversion circuit is realized. Moreover, the composition of the circuit is simple, so the circuit size does not depend on operating frequency. For design of the RF-DC conversion circuits, LE-FDTD method is used. The measurement results agree with analytical results of the LE-FDTD method very well, and availability of the LE-FDTD method is discovered. It is shown that LE-FDTD method is a powerful analytical way which can give efficient design of RF-DC conversion circuit with high conversion efficiency.
