Title:
ELECTROMAGNETIC ENERGY FOCUSING DEVICE, PLANE WAVE GENERATOR, AND WIRELESS CHARGING TRANSMITTER
Document Type and Number:
WIPO Patent Application WO/2023/050087
Kind Code:
A1
Abstract:
An electromagnetic energy focusing device (50), a plane wave generator (40) and a wireless charging transmitter (10), relating to the technical field of wireless charging, and capable of solving the problem of a wireless charging transmitter (10) only being able transmit a focused beam to a specific position. The electromagnetic energy focusing device (50) comprises multiple radiating elements (60), a radiating element (60) comprising a first antenna (601), a second antenna (602), a phase delay line (606), a first diode (D1), a second diode (D2), a third diode (D3), and a fourth diode (D4); the first antenna (601) comprises a first antenna body (6011) and a first branch (6012); and the second antenna (602) comprises a second antenna body (6021), a second branch (6022), and a third branch (6023). The phase delay line (606) is separately electrically connected to the third branch (6023) and the second antenna body (6021); the first diode (D1) is separately electrically connected to the first antenna body (6011) and the first branch (6012); the second diode (D2) is electrically connected to the first branch (6012) and the first antenna body (6011); the third diode (D3) is separately electrically connected to the second antenna body (6021) and the second branch (6022); and the fourth diode (D4) is separately electrically connected to the second branch (6022) and the third branch (6023).
