In this paper, a two element antipodal Vivaldi antenna array in combination with an ultra-wideband (UWB) Wilkinson power divider feeding network is presented. The antennas are placed in a stacked configuration to provide more gain and to limit cross talk between transmit and receive antennas in radar applications. Each part can be realized with standard planar technology. For a single antenna element, a comparison in performance is done between standard FR4 and a Rogers ® RO3003 substrate. The antenna spacing is obtained using the parametric optimizer of CST MWS ® . The performance of the power divider and the antenna array is analyzed by means of simulations and measurements.

“…A few approaches have been discussed in the open literature on how to improve the bandwidth of the Wilkinson power divider. One of the notable examples in [4] shows the bandwidth of the power divider is increased using one added stepped-impedance open-circuited radial stub. However, the bandwidth of the Wilkinson power divider can be simply increased by using multi-section approach [5][6].…”

This paper investigates the performance of two Wilkinson power dividers over a wide band frequencies range from 1 to 13 GHz. The first power divider is designed and developed using single section method while the second power divider is designed using double section method. The main purpose of this study is to determine how much bandwidth improvement can be achieved using double section compared to single section approach. Both designs are investigated using CST Microwave Studio simulation tool. The designs are fabricated on microstrip printed circuit board and measured using vector network analyzer. The simulated and experimental results of both developed dividers are compared and analyzed.

“…When the power divider circuit is needed in planar microstrip configurations, two particular configurations are often used; radially oriented lines [1–4] and fan‐out Wilkinson‐type power divider [5–7]. The radially oriented lines type power divider includes sectorial, triangular and sinusoidal shapes configuration.…”

In this letter, the numerical and experimental investigation of triangular‐shaped microstrip power divider is designed for C‐band applications using defected ground structure (DGS).Numerical simulations are carried out using different computer‐aided design tools based on different numerical techniques, i.e., Ansoft HFSS and CST Microwave Studio. Good agreement is found between the calculated results using both HFSS and CST. A parametric study is carried out to address the effect of DGS parameters on the performance of the proposed triangular‐shaped microstrip power divider. A power divider prototype is fabricated and tested experimentally. Measured results agree well with numerically calculated results. © 2012 Wiley Periodicals, Inc.
