“…The two power divider architectures are T-junction and the Wilkinson power divider. Wilkinson power divider has the advantage of isolation between and matched at all ports [9][10][11][12][13][14]. However, using lumped elements to isolate between the output ports makes it bulky.…”

In this paper, a high power, air suspended stripline (SSL) T junction power divider at L band microwave frequencies is introduced. The power divider operating frequency is centered at 1.3 GHz. In this new configuration, the only dielectric used is air to have maximum power handling capability. An excitation transition from coaxial cable to the SSL transmission line is explained. The SSL was fabricated using aluminum sheets to gain the advantage of low cost. The power divider design was validated using circuit and 3D full wave simulations and confirmed using experimental measurements with all agreements. It has been proved that the power divider attenuation has sharp rejection characteristic at the designed frequency (−20 dB at 1.3 GHz). The power divider can be used as a feeder for devices used in high power applications.

“…Moreover, some of the transmission lines used in the T-junction can be very narrow and this could lead to problems in power handling. An example of a T-junction in a stripline technology is presented in [3]. The Wilkinson power divider has the advantage of a simultaneous match on all ports and an isolation between the output ports [4].…”

In this paper the authors present a novel power divider architecture intended to be used with the Suspended Strip Line (SSL) transmission line. The new antenna array systems, that are designed to work in the millimetre wave ranges, are suffering from the losses in their beam forming networks. In order to mitigate the losses one can use special types of transmission lines. One of them is the so-called Suspended Strip Line (SSL). In this paper the authors present a novel RF power divider intended to be used with the SSL. It uses the properties of the suspended stripline geometry in order to give the designer an increased number of degrees of freedom to achieve the desired power division ratio and a good input match. The advantages of the proposed geometry are compactness, good power handling, no need of any soldering or introducing lumped elements and the sole use of standard 50Ω lines.

“…Provided that the misalignment between the fine and coarse models is not significant, space-mapping-based algorithms typically provide satisfactory results after only a few evaluations of the fine model. Space mapping is mostly used in microwave engineering (e.g., [1][2][3][4][5], [7][8][9][10][11][12][13][14][15][16]) but is increasingly popular in other areas [17][18][19][20][21][22][23]. In the microwave area, fine models are often based on fullwave electromagnetic simulations, whereas coarse models may be physically-based circuit models.…”

Space mapping algorithm with improved convergence properties for microwave design optimization

Space mapping is one of the most efficient techniques for microwave design optimization. Still, it is well known that space mapping algorithms may suffer from convergence issues, which are consequences of certain fundamental features. In many cases, the space mapping algorithm quickly finds an acceptable solution, but then falls into oscillations with respect to the design variables and/or the objective function value; as a consequence, there are no clear criteria for terminating the optimization process. In this article, we investigate some techniques for improving the convergence properties of the space mapping algorithm, which are based on the general convergence results for such algorithms. Our approach is verified using several microwave design optimization problems.
