Design and Analysis of a Frequency Reconfigurable Microstrip ... the other is designed using PIN diodes to enable switching between two different frequency bands. Silicon made optical switches have been used by some researchers to construct frequency reconfigurable antennas [24]. Some compound reconfigurable antennas using PIN diodes [25] and optical switches [26] have also been reported in the past. Investigations on Reconfigurable Dual Frequency Microstrip ... bothering about the antenna dimensions. Even though the PIN diode controlled reconfigurable antenna scheme described in the earlier section permits this, a n_r9,re_ flexible frequency tuning scheme can beaccomplished by‘ replacing the PIN diodes with Varactor diodes. Here Varactors are integrated with the extended slot ann of the dual frequency 3.1 Introduction - INFLIBNET

Evaluation of Modeling Accuracy of Reconfigurable Patch Antennas Abstract-Evaluation of frequency reconfigurable patch antennas for multi-standard personal communication systems, using PIN diodes as switches. Two different configurations are studied with dual-band behavior: a patch antenna with two switchable slots; and a Draft Version A Reconfigurable Radiation Pattern Annular Slot ... in reconfigurable antenna has emphasized the use of pin diodes. By referring to [19][20][21][22][23][24][25], different types of antenna had employed pin diodes in the antenna structure to attain diversity in radiation pattern.
