Two 90‐degree conical horn antennas prototypes were designed and characterized to achieve wide beamwidth at 60 GHz in order to receive multipath signals in a mobile environment. The antennas consist of a circular waveguide and a flange with one and three annular slots. A simulated half‐power beamwidth of 112 degrees was reached for the antenna with one annular slot and 115 degrees for the antenna with three annular slots. Some tests were realized and the results compared with the simulated ones showing good agreement.© 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 58:2731–2738, 2016
