Abstract:small-signal gain, for a given millimetre-wave output frequency, was essentially independent of the LO frequency whether the output was in the lower or upper sideband of the LO, as determined by the relationship between the LO and IF frequencies. The smallsignal gain of the transmitter is therefore shown in Figure 4 as a function of output frequency only. It can be seen that the smallsignal up-conversion gain falls approximately monotonically from 0 dB, for output at 176 GHz, to Ϫ15 dB, for output at 190 GHz.T… Show more
“…Like other Yagi antennas and arrays [1][2][3][4][5][6][7][8][9][10], all the presented Yagi antenna and arrays in our work have the tilted beam. Usually, an effective method to adjust the beam steering angle is to change the number of director element according to the principle of field superposition.…”

“…Based on these antennas, many microstrip Yagi arrays have been developed to extend the performance. By duplicating the microstrip Yagi antenna perpendicular to the projective direction of the tilted beam, linear arrays would be obtained [5][6][7]. This method of array arrangement is mainly used to achieve a high gain greater than 10 dBi.…”

“…This method of array arrangement is mainly used to achieve a high gain greater than 10 dBi. In addition, electronic scanning could be achieved by feeding each element with calibrated phase shifters [6]. Another array arrangement is the crossed Yagi array [8][9][10][11], which usually shares a common element at the center.…”
