[IEEE 2019 PhotonIcs & Electromagnetics Research Symposium - Spring (PIERS-Spring) - Rome, Italy (2019.6.17-2019.6.20)] 2019 PhotonIcs & Electromagnetics Research Symposium - Spring (PIERS-Spring) - A GaAs Integrated Power Divider Based on Microstrip and LC Structure with Optimized Capacitance
摘要： In this paper, a microstrip LC two-section Wilkinson power divider based on GaAs IPD process is proposed. A method on adjusting circuit parameters is demonstrated, which can compensate the parasitic e?ects of frequency-dependent passive components. One of the sections is a lumped LC network and the other section consists of microstrip lines. This design can reduce the size of the power divider and avoid a high loss. The inductance and capacitance of this power divider are calculated to ensure that the LC network is equivalent to a microstrip line. However, the capacitances and inductances are all sensitive to frequency so there is a signi?cant variation among calculation with ideal components and simulation with practical models. To solve this problem, even-mode input admittance is studied. By plotting a polar diagram of ideal and simulated even-mode input admittances, it is clear that a di?erence exists among simulation and ideal target, which causes the performance degeneration. This polar diagram also indicates a method on optimizing the admittance by increasing capacitance in the LC network. Increased capacitances are utilized in power divider simulation. Simulated results are compared and an optimized capacitance, which guides our ?nal design, is obtained. This power divider is fabricated using GaAs IPD process and measured on wafer. Measurement agrees well with simulation: operation band is 2.850 GHz to 4.832 GHz. A 1.982 GHz bandwidth is achieved. The insertion loss of port 2, 3 is less than 1.30 dB in this frequency range, and the isolation is higher than 18.5 dB.

摘要： This paper presents a design of phased array antenna using a full 360o and programmable continuous phase shifter based on angle of arrival techniques of indoor localization. This antenna system allows to electrically steer main beam direction smoothly, so the number of beams is independent of the number of antenna elements as previous research, and resolution for indoor localization system is improved. Antenna elements are fed through parallel feed network including Wilkinson power dividers and full 360o, continuous phase shifters. Radiation patterns, experimented from -45o to 45o in an anechoic chamber, show that the main beam direction is quite close to the desired direction in simulation, and the side lobe level is less than main beam about 10dB.

FILTERED POWER SPLITTER USING MICROSTRIP SQUARE OPEN LOOP RESONATORS
摘要： A microstrip power splitter with band-pass responses is presented in this paper. The design is based on square open loop resonator topology. This ?ltered power splitter does not require quarter wavelength transformers and will result in a smaller size than a conventional Wilkinson power divider with integrated band-pass ?lter. It is a two-way equal power splitter with ?fth order band-pass ?lter characteristics. The power splitter is designed to have Chebyshev band-pass response function. A theoretical analytical circuit model will be presented. From the theoretical model, a microstrip ?ltered power splitter will be designed and simulated. The proposed ?ltered power splitter is small in size and reduces circuit complexity. The power splitter is simulated and measured, and the results are presented.

[IEEE 2018 48th European Microwave Conference (EuMC) - Madrid, Spain (2018.9.23-2018.9.27)] 2018 48th European Microwave Conference (EuMC) - Compact and Wideband CPW Wilkinson Power Dividers for GaN MMIC Applications
摘要： This paper presents two types of modified CPW Wilkinson power dividers at X-band using GaN MMIC technology on a SiC substrate. Lumped element equivalents of the transmission line arms are used and they are capacitively loaded to achieve a reduced circuit size of λ/14 × λ/8. A symmetrical series RLC circuit in the isolation network is used to compensate for the bandwidth degradation after circuit miniaturization maintaining a fractional bandwidth of 29% for input/output return losses and isolation better than 20 dB with an extra insertion loss less than 0.35 dB.

TWO-WAY MODIFIED WILKINSON POWER DIVIDER FOR UWB APPLICATIONS USING TWO SECTIONS OF UNEQUAL ELECTRICAL LENGTHS
摘要： This paper presents 2-way Power Divider (PD) for Ultra-Wideband (UWB) applications. The proposed power divider is realized using two cascaded sections of Wilkinson Power Divider (WPD) of equal characteristic impedances and unequal electrical lengths with inserted open stub to improve matching, isolation and to broaden the bandwidth. It is proved analytically using the “Even Odd Mode” analysis method and the ABCD matrix to obtain exact closed-form design equations. A detailed design methodology is introduced to facilitate the implementation without needing CAD optimization. To verify the proposed design methodology, a 2-way power divider is designed, fabricated on a Rogers RT/Duroid 5880 substrate and compared to other published 2-way microstrip power dividers. Measured data show good agreement with Electromagnetic (EM)-Circuit Co-Simulation, which proves the design equations and methodology. The proposed planar 2-way PD achieves an isolation ≥ 13.5 dB, input return loss ≥ 10 dB, output return loss ≥ 14.5 dB and exceeded insertion loss ≤ 0.9 dB (over the ?3 dB splitting ratio) through the whole UWB range from 3.1 GHz to 10.6 GHz. Furthermore, it has a compact area of 22 mm × 15 mm, which provides 50% enhancement over similar microstrip PD circuits while achieving better isolation and matching.
