Both self-interference (SI), which is caused by imperfect channel estimation, and co-channel interference (CCI) are considered in multiple-input multiple-output systems employing maximal ratio combining under independent and identically distributed Rayleigh fading. Closed-form expressions for probability density function and outage probability of output(More)
—A novel sideband radiation (SR) level suppression method for the time-modulated array (TMA) is proposed. By modulating their front-end RF switches with nonuniform periods, the SR level of the TMA can be remarkably suppressed, compared to using uniform periods. Numeric simulations are brought out to examine the performance of the proposed approach, and the(More)
In this paper, a three-way reconfigurable power divider/combiner is proposed based on novel switch element with matching network (SEMN) and reconfigurable impedance transformer network (RITN). A good matching performance and a high isolation of the SEMN with one p-i-n diode can be obtained by the parasitic inductance and reverse capacitance of the p-i-n(More)
Full-wave de-embedding refers to a network de-embedding technique in which the fixture effects are removed by characterizing any connection interface using a full-wave EM simulation method instead of by measurement alone. This technique is able to achieve consistent definition of equivalent circuit voltage and current when the de-embedded results are used(More)
This paper presents the analytical and experimental works on coping with the popularity in wireless communications, especially in satellite communication. Firstly, the “image element” and “arc-shaped orthogonal feeding network" technologies are introduced for the single-band single-polarization antenna array design, the cross(More)
The design of a 600 MHz non-Foster dipole is presented. The antenna and NIC layout are modeled together using HFSS to include the mutual coupling effects between these two parts. With the formulation developed, the return loss and radiation efficiency of the non-Foster dipole can be calculated and optimized simultaneously in the circuit simulator ADS. The(More)
—Power divider is widely used in the phased antenna array. In this paper, a novel ultra-wideband divider with high isolation is proposed, which bases on the multi-section transmission line theory to extend the bandwidth of the power divider and the multilayer technique to reduce the size of the power divider. The simulated isolation of power divider is(More)
—Two improved circularly polarized microstrip planar antennas operating in 5 GHz–6 GHz are proposed in this paper. The Swastika slot and a circular feeding line are introduced into Ant.2 which exhibits wide impedance bandwidth and AR bandwidth during simulation and measurement than a basic truncated edge CP microstrip antenna. In further studies, a center(More)
