Abstract
In the paper, an influence of antennas transmitting the electromagnetic wave to the sample cell of a millimeter-wave molecular spectrometer on the properties of the whole device is discussed. A conventional rectangular horn antenna is considered as the reference antenna, and a double ridge horn antenna is designed, modeled and optimized in order to improve parameters of the spectrometer potentially. A detailed comparison of the reference antenna and the double ridge horn shows that a wider frequency band can be covered by the designed antenna, but the gain achieved is lower.
