Kenji Irie, Nobuhiro Kuga, Keizo Cho
2011 IEICE Electronics Express  
In 2 GHz-band experiment, we shows that the size reduction of the diode-mounted hole has an equivalent effect of the diode-rotation in the previous work, and contributes to the linearity improvement in  ...  A new method for the dynamic range enhancement of the PIM-producing patch antenna with diode is proposed, and its effectiveness is verified by experiment.  ...  In 2 GHz-band experiment, the size reduction of the diode-mounted hole contributed to the linearity improvement in the high power excitation, which was caused by the PIM reduction.  ...
