This paper presents an anti-symmetric wing transmitter (ASW-Tx) for angular misalignment insensitive WPT to biomedical implants. Symmetrical field distribution on two orthogonal planes of <inline-formula> <tex-math notation="LaTeX">$Oxz$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$Oyz$ </tex-math></inline-formula> are analyzed theoretically to obtain stable power transfer efficiency (PTE) by rotating Rx around the <inline-formula> <tex-math notation="LaTeX">$Oz$ </tex-math></inline-formula> axis. Moreover, toroidal magnetic fluxes are generated by ASW to adapt with different Rx&#x2019;s tilted angles on <inline-formula> <tex-math notation="LaTeX">$Ox$ </tex-math></inline-formula> and <inline-formula> <tex-math notation="LaTeX">$Oy$ </tex-math></inline-formula> axes. An impedance matching network (IMN) is proposed and implemented to match ASW-Tx&#x2019;s impedance to source impedance. An implantable Rx is employed to verify the ASW-Tx&#x2019;s performance. Experimental measurements are carried out with selected Rx&#x2019;s tilted angles (vary from <inline-formula> <tex-math notation="LaTeX">$0^{o}$ </tex-math></inline-formula> to <inline-formula> <tex-math notation="LaTeX">$90^{o}$ </tex-math></inline-formula> around <inline-formula> <tex-math notation="LaTeX">$Ox$ </tex-math></inline-formula>, <inline-formula> <tex-math notation="LaTeX">$Oy$ </tex-math></inline-formula>, and <inline-formula> <tex-math notation="LaTeX">$Oz$ </tex-math></inline-formula> axis) to validate the effectiveness of proposed ASW-Tx&#x2019;s. Verification results show that a stable efficiency variation was achieved with a maximum fluctuation of 4 dB by rotating Rx tilted angles. Moreover, the ASW-Tx can supply power effectively with a transmission efficiency of up to -18.4 dB to an implantation depth of 15 mm.
