Wearable devices are worn directly on man and one of the most important attribute for wearable devices is “user experience” friendly[1]. Wearable device is small in size, it is difficult to carry large capacity battery. the short duration of the battery and charging difficulties and other issues has become a universal response of all users, which seriously affect the user experience. Wireless energy...
Compact voltage tunable phase shifters on yttrium iron garnet/lead magnesium niobate lead titanate heterostructure are presented. A comparison of E-field tunability between 1-layer PMN-PT structure and two-layer PMN-PT structure using bending mode is discussed. The device exhibited a phase shift of 119 under an electric field of 11 kV/cm. The device combining with multiferroics and partially...
A compact magnetically tunable bandpass filter on partially magnetized yttrium iron garnet (YIG) substrate is presented. The bandpass filter led to a large frequency tunability of 7% (from 5.77 to 6.2GHz) under a low bias field of 0 to 100 Oe, while partially magnetized ferrites exhibit a tunable permeability μr range from 0.71 to 0.94. The bandpass filter also exhibited a good impedance match and...
A new type of non-reciprocal C-band magnetic tunable bandpass filter with ultra-wideband isolation is presented. The BPF was designed with a 45° rotated yttrium iron garnet (YIG) slab loaded on an inverted-L shaped microstrip transducer pair. This filter shows an insertion loss of 1.6∼2.3dB and an ultra-wideband isolation of more than 20dB, which was attributed to the magnetostatic surface wave. The...
