Abstract—Slotted waveguide antenna (SWA) arrays offer clear ..For example, the predetermined distance can be in the range of 0.5 λ to 0.9λ, and preferably about 0.7 λ where λ is the desired operating wavelength of the antenna. Frequency and Pattern Reconfigurable Slot Antenna - IEEE Xplore A Corner Reflector Antenna on Slot Antenna Driven .. ANTENNA RECONFIGURABLE MICROSTRIP CONTROLLED DUAL-FREQUENCY ... dual-frequency coplanar strip dipole antenna was described in [2]. A pin-diode-controlled dual-frequency reconfigurable square-mi-crostrip antenna with a hexagonal slot has recently been reported 131. In this paper, we present novel designs of a compact single-feed reconfigurable dual-frequency square-microstrip antenna con- A Compact Flexible and Frequency Reconfigurable Antenna for ... 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 ...

reconfigurable circuitry that operates on each of these different frequencies. A Reconfigurable microstrip patch antenna is an antenna which can expand the system capability by adjusting its resonant frequency, radiation pattern and polarization. Reconfigurable antennas are becoming more important in defense and commercial
