Varactor Diodes, or varicap diodes, are used primarily in electronic tuning circuits. Their unique property is the ability to change their capacitance based on the voltage applied to them. This makes ...

Figure 2: Equivalent circuit to describe the transition capacitance In some applications, the transition capacitance is used and the corresponding device is known as a varicap (or varactor ) diode, ...

It is based on split-ring resonator (SRR) unit cells, tuned by varactor diodes, comprising 1,024 elements arranged ... angular reciprocity reported in the literature, validating its application to ...

2014.]. Trapezoidal geometry was chosen due to the good resonant frequency reconfiguration sensitivity when the varactor diode present between the resonators has its capacitance changed due to the ...

Abstract: This paper presents a beam-steerable dipole antenna using varactor diodes for WiMAX applications. The proposed antenna consists of dipole antenna, two parasitic elements, and varactor diodes ...
