Reconfigurable antenna - Wikipedia

D. Radiation and Frequency Reconfigurable Antenna In general, most antennas are capable of either frequency or pattern reconfigurability. However, they can be made a combination of both frequencies and pattern reconfigurable simultaneously. Frequency and Pattern reconfigurable microstrip antenna are done by using FREQUENCY AND PATTERN RECONFIGURABLE YAGI ANTENNA: Journal of ... A novel frequency and pattern reconfigurable Yagi antenna is proposed. The antenna is formed by a driver, a reflector and two directors. The introduction of switches using a PIN diode at the arms of the driver element produces three switchable frequencies at 1.25 GHz, 1.85 GHz and 2.45 GHz. By ... DESIGN AND IMPLEMENTATION OF RECONFIGURABLE PATCH ANTENNAS ... and validated at the expected frequency bands. For the new reconfigurable antenna array, the beam pattern selectivity can be obtained by utilizing a switchable feeding network and the structure of the truncated corners. Opposite corners have been slotted on each patch, and a diode on each slot is used for switchable patterns. Survey on Different types of reconfigurable Patch Antenna for ...

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. Frequency and Pattern Reconfigurable Slot Antenna A frequency and pattern reconfigurable slot antenna was presented in [18] with reflector size of 304 × 130 mm 2 and overall size of around 304 × 130 × 160 mm 3. It covered 1.82 GHz, 1.93 GHz Pattern and frequency reconfigurable annular slot antenna
