EM Insights Series - Single and Multiple Band Microstrip Planar Array Antenna
The major bottleneck in a planar microstrip patch antenna design is the capacity and speed issue of the field solver to handle a large size array antenna. The situation becomes more complicated when the antenna is used for multiple bands. In the past, the antenna problem was usually broken down into small sizes that were integrated (linearly added) later without carrying out an EM simulation at the full structure level. In this way, the coupling at the large structure level was not taken into account. This episode demonstrates how the new improvements to Momentum aids designers of large array of microstrip patch antennas.
