“…Moreover, the output ports of the circuits in [6][7][8][9][10][11]13] are rectangular waveguide ports, which is inconvenient to integrate with other planar circuits such as power amplifiers, low noise amplifiers, and so on. Furthermore, the impedance-transformation stages in [7][8][9][10][11] are based on waveguide stepped-impedance transformers, and the isolation cirin [7,8,[10][11][12][13] are exposed outside. These drawbacks create a hurdle to further improve the circuit's integration level and result in a large circuit size.…”

“…It consists of a standard WR-28 waveguide as the input port, two microstrip line output ports, and an insulator. The ridge waveguide, function as an impedance transformer between waveguide and planar transmission line, is hidden in the standard waveguide, so the whole circuit size is more compact than the circuit in [10][11][12] in which the impedance transformation is accomplished by stepped-impedance waveguide. The isolation between two output ports is realized by an insulator which is inserted into the junction from the bottom of the substrate.…”

“…The isolation between two output ports is realized by an insulator which is inserted into the junction from the bottom of the substrate. Two chip resistors connect with the insulator by two microstrip lines which are also hidden in the waveguide, whereas the isolation circuits in [7,8,[10][11][12][13] are exposed outside which results in a large circuit size. The substrate used in this circuit is Rogers RT/Duroid 5880 with a thickness of 0.254 mm, loss tangent of 0.0009, and relative dielectric constant of 2.2.…”

“…Isolation between two output ports was realized by introducing a metallic strip probe into the center of the T-junction, the energy coupled by the probe is absorbed by a matched load. Two power dividers which share this similar design concept were proposed in [11, 12]. In [13], a waveguide power divider was realized by properly arranging the configuration and dimensions of the coupling region to control the propagation constants of TE10 and TE30 modes.…”

A waveguide power divider based on ridge waveguide to microstrip line transition is presented in this paper. To improve the isolation performance, a probe insulator is inserted into the contact face from the center of the waveguide side wall, also two chip resistors are mounted on a planar substrate and connected with the probe to absorb the coupled energy. The impedance transformation is accomplished by ridge waveguide to microstrip line transition, which is hidden in the waveguide. This proposed power divider shows merits of waveguide power dividers and substrate-integrated waveguide power dividers simultaneously, i.e. planar output ports, compact size, and high isolation. For verification, a power divider operating at the Ka-band is simulated, fabricated, and measured. The obtained results show the return loss and isolation are better than 10 and 20 dB, respectively. The measured insertion loss is <1.5 dB, including the insertion loss of waveguide to microstrip line transitions at the output port in the range of 34.6–39 GHz.

Exploring low-frequency (LF) arbitrary power-splitting technologies to address the independent excitation issues of LF/VLF mechanical antennas (MA) with random distributions is challenging due to unidentified device construction and operation mechanism. In light of this, a device construction strategy for three-port magnetoelectric (ME) arbitrary power splitter in composite of ferrite/piezoelectric heterostructure, as well as theoretical model was developed. To validate the feasibility and effectiveness of the strategy, three size-tailored ME samples with length ratio of split PZT segments in 1:1, 2:1, and 3:2 were modeled, fabricated and comparatively characterized. Experimental results show that the achievable maximum power conversion efficiencies (PE) reach 52%, 71%, and 59% for three tailored ME samples, respectively, and as expected the power-splitting ratios are directly proportional to the square ratio of ME voltage coefficient (MEVC) from each port of the tailored ME samples, which are in coincidence with theory under desired operation stability and favorable experiment repeatability evaluated by uncertainties of 0.25854 V/cm Oe and 0.32979 V/cm Oe for each port. Therefore, a prediction of evolutionary tendency for arbitrary power splitter realization was expanded in view of our experimental observations, and a great flexibility for device future design and further optimization was also provided. Therefore, the presented LF power-splitting strategy paves the ways for arbitrary power splitter realization and enriches the multi-functional ME power electronics families, as well as enables potential applications for efficient excitations of MAs in high-permeable military underwater and civilian emergency rescue distribution long-wave communication system for practical scenarios of submarine, underground railways, tunnels and collapsed residential buildings.
