Investigation of the Asymptotic Properties of Active Impedance in Large Finite Array Antennas
Harald Hultin, Lucas Åkerstedt, B. L. G. Jonsson
This paper presents an improved full-wave solver for finite array antennas, and uses this solver to examine asymptotic properties of active impedance for large regular arrays. The…

Solver Performance of Accelerated MoM for Connected Arrays
Harald Hultin, Lucas Åkerstedt, B. L. G. Jonsson
Simulating and developing large rectangularly shaped arrays with equidistant interspacing is challenging as the computational complexity grows quickly with array size. However, the…

An Array Decomposition Method for Finite Arrays with Electrically Connected Elements for fast Toeplitz Solvers
Lucas Åkerstedt, Harald Hultin, B. L. G. Jonsson
A large part of the geometry of array antennas is often partially defined by finite translational symmetries. Applying the method of moments (MoM) with the RWG-like element on an a…
