Hello, nowadays I am working on antenna array and I have 1x2 array. So my aim is changing the length of the input line so that it will effect the phase of E field and with that I will have done beam steering. I read some discussion and saw that people get phase using "polyline" and they draw on where the E field is maximum I think. But is it really the only way that we have ? I mean in the plot section I tried rE_total, rE_phi-theta with and_deg and that did not help. But I did not understand why do we need to draw polyline is there any easier way that exists ? Becaus I do not want to draw polyline in every time. Also I want to ask that for beam steering, I consider the phase of E field but can I also use directivity vs theta ?

Hi,

Thank you for reaching out to the Ansys learning forum.

It is possible to plot the Electric field phase along a polyline defined along the feed using the "Create Field Report" feature of Results in Ansys HFSS. 

Alternatively, you can also use Finite Array Domain Decomposition Method (FADDM) to create finite array using less resources than explicit array without compromising on accuracy. In this appraoch, Finite Array Beam Angle toolkit can be used to edit the exciations for beam steering purpose.

The quantities - rE_total are  rE_phi far field quantities and not the electric field on the antenna. Please go through "Selecting a Far-Field Quantity to Plot" section of the HFSS help document for more information on understanding these quantities.
