This paper presents S11 measurements of a flat, slotted, sub-mm sized antenna, integrated with a Schottky diode; the overall structure being termed a ‘multenna’ in description of its action to radiate a signal beam field that is a higher order harmonic of the signal beam field it receives. The multenna is constituted of two square slots; one tuned to receive at the frequency of 100 GHz and the other to radiate at 300 GHz. The S11 readings are acquired using a cascade probe station driven by a Vector Network Analyzer (VNA). The investigated frequency domain of this study is 70–110 GHz (WR-10 waveguide band). Simulation results agree in key features with measurements over the band, thereby verifying the measurement procedure and validating the use of a lumped-element approach to represent the diode impedance.
