an antenna element and a patch on the same side of the substrate. One pin diode is employed in the T-shaped an-tenna for WLAN and WiMAX applications. However, its gain is comparatively low and its fabrication is expensive [19]. In this paper, a novel compact, flexible and frequency reconfigurable antenna is proposed. Both features; flexibil- Pattern and Frequency Reconfigurable Annular Slot Antenna ... Return loss and radiation pattern measurements and simulations are presented, which are in very good agreement. Index Terms—Annular slot antenna (ASA), frequency reconfigurability, pin diode, reconfigurable antenna, reconfigurable radiation pattern, slot antenna. I. Frequency and Pattern Reconfigurable Slot Antenna - IEEE ... Slot antenna produces a bidirectional radiation pattern, thus a reflector is positioned behind of the antenna to generate a directional radiation pattern. Two switches are placed in the slot to produce three reconfigurable frequency bands: at 1.82 GHz, 1.93 GHz and 2.10 GHz. The introduction of four slits at the edge of the ground plane offers ... 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.
