In this study, a unique design in frequency reconfigurable antenna approach is proposed .The shown design in this paper can be used for Ku band downlink especially in satellites. A special em ployment includes a rectangular slot with four PIN diodes where the frequency reconfigurability is obtained. (PDF) Pattern and Frequency Reconfigurable Annular Slot ... The reconfigurable ASA proposed in this paper operates at three frequencies with a central frequency at 5.8 GHz, and it also Index Terms—Annular slot antenna (ASA), frequency reconfig- has a reconfigurable radiation pattern that can position a null urability, pin diode, reconfigurable antenna, reconfigurable radia- tion pattern, slot antenna. Frequency and pattern reconfigurable Yagi patch antenna ... Thus, a design that is reconfigurable in both frequency and radiation pattern is accomplished. As a proof of concept, five models are fabricated and tested. Three of them operate at the higher frequency and two of them at the lower one. The main beams of these models point to different directions in the E‐plane.

By changing the states of the slots etched on different parasitic element patches, directions of the radiation pattern can be changed. Thus, a design that is reconfigurable in both frequency and radiation pattern is accomplished. As a proof of concept, five models are fabricated and tested. Frequency Reconflgurable Microstrip Patch-Slot Antenna with ... switches are placed in the slot. The antenna is capable to reconflgure up to six difierent frequency bands from 1.7GHz to 3.5GHz. The microstrip patch antenna produces three difierent frequency bands with directional radiation pattern while the microstrip slot antenna produces another three frequency bands with bidirectional radiation pattern.
