Frequency reconfigurable patch antenna using PIN diode at… A combination of PIN diode and varactor diode is used in [12] where a reconfigurable slot antenna is capable to reconfigure up to nine frequency bands. In this paper an annular slot rectangular patch antenna has been shown at X band by which frequency tunability can be obtained up to ±60. Reconfigurable Antennas | Figure 10. A diagram of a PIN … A reconfigurable antenna modifies the antenna’s pattern, polarization, or frequency/bandwidth in some desirable fash-ion. For instance, a reconfigurable antenna might steer or place a null in an antenna’s pattern, switch from right-hand circularly polarized to left-hand circularly polarized, or move...

frequency bands in the range of 0.54GHz to 0.95GHz. Four PIN diodes are used to tune the length of the slot thus provides four difierent frequency reconflgurations. PIN diodes are used in [22] where the antenna is capable to switch between 2.4GHz and 2.9GHz. By using two PIN diodes, the designed antenna is capable to operate in two modes.
832 Seung-Bok Byun et al. ETRI Journal, Volume 29, Number 6, December 2007 ABSTRACT⎯This letter presents a reconfigurable ground- slotted patch antenna using a PIN diode connection in slots to achieve dual-frequency operation. Slots in the ground plane increase the electrical length and thereby reduce antenna size A Frequency Reconfigurable Rotatable Antenna Design for ... In this design, the rotatable reconfigurable antenna has the advantage that there is no need of bias lines which affects the radiation characteristics of the antenna. RF-MEMS/PIN diode-based reconfigurable antenna systems require the use of bias lines. It also requires the bias lines to lie on the same plane as that of the antenna. Pin diode in reconfigurable antennas - edaboard.com Hello I am working on reconfigurable antennas.I have simulated one design with switching element as pin diode. It is easy to switch the pin diode during designing of antenna. How can we switch the pin diode after fabrication of antenna???Do we need any extra supply for that. If we add some supply to change biasing of pin diode,it will lead to a concept of multiple feeds to antenna. Design of Frequency- and Pattern-Reconfigurable Wideband ... A wideband slot antenna with frequency- and pattern-reconfigurable characteristics for TD-LTE (3.4–3.8 GHz) and C-band (3.7–4.2 GHz) applications is proposed. The antenna consists of two symmetric slots that are fed by a fork-shaped microstrip line. Two PIN diodes are loaded in the slots to produce two different frequency bands.
