Design and Simulation of a Compact Planar Micro-strip Crossover for Beam forming Networks using HFWorks for SOLIDWORKS

In this article, a compact planar crossover is designed using the CAD SOLIDWORKS and simulated using the full wave 3D simulator HFWorks. An S Parameter analysis is conducted to investigate the electromagnetic behavior of this structure.

The compact planar crossover example is formed of a square micro-strip patch excited by four perpendicular micro-strip lines. The square patch comprises two perpendicular rectangular slots and four arc-shaped slots. The resonance frequency of this structure is 2.4 GHz.

HFWorks results are generated and compared to measurements. they are showing a good agreement. The return loss is greater than 10 dB for 2.3 - 2.54 GHz while the insertion loss is less than 1 dB. The isolation is more than 13 dB.

The distribution of the electric field at the resonance frequency 2.4 GHz is computed using HFWorks under 1W as power excitation. More Details
