Dr. Shiban Koul of Indian Institute of Technology Delhi

Future millimeter wave 5G commercial devices would have transceivers operating in the 28GHz band. These devices would need antennas to establish a reliable link between the mobile device and the nearest base station. The primary issue with the design of reliable communication links in the 28GHz band is the high propagation loss, in addition to this attenuation encountered in various common building materials
would reduce the signal. The only feasible solution for achieving these specifications would be to integrate the mobile device with high-gain antennas. High-gain antennas would conventionally occupy a larger electrical and physical footprint, which would hinder the utility of these antennas. Hence, anel mountable antennas with high gain and low physical footprint would be necessary to future-proof wireless devices.
The antenna to be designed must deliver high gain for minimal electrical dimensions, in addition to compatibility with the panel height of modern smartphones. The antenna system must also be able to switch beams for landscape and portrait modes. In this lecture, a wideband microstrip-fed antenna is realized on a low-cost substrate. The same antenna is investigated for the orthogonal pattern diversity topology.
