An antenna array for a portable electronic device includes at least two antennas 1, which may be leaky wave devices, each antenna having at least two radiating elements 3. Multiple control networks 2 comprising RF switches 13, 18 connect each antenna to a respective single RF port by way of...
Once the mesh is created, HFSS can be used to assess and optimize the antenna’s gain, return loss, side lobe and beam steering with more accuracy than in step 2. STEP 4: Calculate the Beam Angle of the Finite Antenna Array An antenna is of little use if engineers can’t control wher...
With the help of Ansys HFSS, these engineers can create 5G antenna array designs in 8 steps. HFSS can also help engineers optimize the antenna’s properties, like: A 3D polar plot of an antenna created using HFSS Gain— the direction in which the signal is strongest. Beam steering — the...
