The future is likely to see millimeter-wave systems used in urban street canyons for high data rate communications. Space limitations in urban areas will necessitate using small size antennas for building millimeter-wave systems in mobile front-haul application. Such antennas have broad beamwidth and consequently the systems in street canyons will incur multi-path interference. This letter addresses the issue of such multi-path interference. We conducted experiments in 72 GHz bands to ascertain
