Frequency Reconfigurable Multiband Antenna with Embedded Biasing Network

What is it about?

This work presents a frequency reconfigurable antenna scheme for wireless communications (WiMAX, m-WiMAX and WLAN), in which a PIN diode is utilized for the discrete tuning and a varactor diode for the subsequent fine-tuning. A microcontroller-controlled embedded biasing network (EBN) is integrated into the antenna to regulate the PIN and varactor diodes for the simultaneous wideband and multiband operations.
