DESIGN OF RECONFIGURABLE ANNULAR SLOT ANTENNA (ASA) FOR WIRELESS COMMUNICATIONS / WLAN APPLICATIONS ... Radiation patterns for the 6.4 GHz frequency design when the short is placed at 225 o. Simulation, measurement with hard-wired short, ... direction using two PIN diodes placed at. 225 o and 315o.The 90 o 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. Pattern and Frequency Reconfigurable Annular Slot ... - CORE As a proof of concept, two pin diodes are placed 45 on both sides of the feeding line along the ASA and the direction of the null is shown to align with the direction defined by the circular slot center and the diode. Consequently, a design that is reconfigurable in both frequency and radiation pattern is accomplished. Design of frequency reconfigurable multiband compact ...

Manos M Tentzeris | Georgia Institute of Technology ... This paper discusses the use of pin diodes to modify the radiation pattern of an annular slot antenna (ASA) keeping constant the frequency of operation. The planar antenna is fabricated on the top side of a Duroid substrate and the microstrip feeding line with the matching network is fabricated on the back side of the board. Planar square multiband frequency reconfigurable microstrip ...
