AbstractThis paper presents the use of pin diodes to recon-figure the impedance match and modify the radiation pattern ofan annular slot antennaIndex TermsAnnular slot antenna (ASA), frequency reconfig-urability, pin diode, reconfigurable antenna, reconfigurable radia-tion pattern, slot antenna . 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...
