The development of 4G and 5G network together with smart phone and its applications in the last 15 years reshaped people’s life today. This seminar would like to review a couple of key challenges and its solutions in cellular antenna design in the last decade particularly from industrial point of view. It discussed the issues due to coupling between radiators in an interleaved placement and working at different bands, and challenges in multi-beam base station antenna design. At the end of the seminar the passive base station antenna’s test solutions are also included with a little touch of 5G OTA measurement.
