Application42 Planar Array Antenna

The array antenna is needed for the 5G communications. It has a set of multiple antenna elements and capable of beamforming. In this application, dipole pattern antennas are arrayed in 3 by 3 on a dielectric substrate, and directivity is simulated.

An analysis model is shown in Fig. 1. A dipole pattern is laid on a dielectric substrate with a feeding portion. Fig. 2 shows the results of 3D directivity. The main beam is concentrated over the center of the the substrate. It is confirmed that the model works as an array antenna. Femtet can set input power and phase for each port.
