still increases, and vice versa. Meanwhile, thanks to the L d , although the gain changes with the different V C , but makes the gain flatness.With above design, the gain can be continuously controlled by the gate bias of MN 3 , and the desired value of gain can be achieved by selecting a right gate bias of the MN 3 .
EXPERIMENTAL RESULTSABSTRACT: A compact dual-band monopolar patch antenna (DBMPA) using the TM 01 and TM 41 modes is proposed. The DBMPA consists of:(1) coupled-fed fan-shaped patches with four shorting pins each to Figure 7 The die photo of the UWB continuously variable gain LNA.
