摘要

提出了一种u槽双频可重构贴片天线。加载变容二极管前的天线谐振频率分别为1.3 GHz和2.4 GHz。可调性是通过p-n变容和铁电可调电容器实现的。发现两个频段的单独调谐是可能的，这取决于电容器的位置。第一个频段实现的最大调谐范围为600 MHz，第二个频段实现的最大调谐范围为422 MHz。较低频段的最小和最大增益值分别为4.25 dBi和4.95 dBi。同样，对于上波段，这些值分别为6.77 dBi和7 dBi。

U-Slot Dual-band Frequency Reconfigurable Patch Antenna Tuned With Commercial Ferroelectric BST capacitors.

A U-slot dual-band frequency reconfigurable patch antenna is presented in this paper. The resonant frequencies of the antenna before loading with varactors are 1.3 GHz and 2.4 GHz. The tunability is achieved using p-n varactors and ferroelectric tunable capacitors. It is found that individual tuning for both frequency bands is possible depending on the capacitor position. The maximum tuning range achieved for the first band is 600 MHz and the same for the second band is 422 MHz. The minimum and maximum gain values for the lower band are found to be 4.25 dBi and 4.95 dBi, respectively. Similarly, for the upper band, those values are obtained as 6.77 dBi and 7 dBi, respectively.
