mmWave Axial Choke Horn Antenna with Lens

Millimeter wave (mmWave) antennas operate in the band of frequencies where the wavelength is between 10mm and 1mm. The frequency range for mmWave application is thus constrained to be greater than 30 GHz, but less than 300 GHz. Various applications exist in this frequency range, including wide band telecommunication and imaging applications for security screening. This white paper demonstrates how an antenna was designed for communication at 60 GHz.
