complicates antenna design and construction. We propose a different approach - a reconfigurable antenna with switches that are powered by the antenna itself. Control signals for switches are part of the antenna transmission, preceding the main data. This concept opens many possibilities for antennas with reconfigurable properties such as patterns, Design Of Reconfigurable CPW-Fed Slot Antenna With Frequency ...

Multiband Reconfigurable Microstrip Patch Antenna Reconfigurable Antenna is an alternative to multi-band Antenna. Different techniques are used to achieve multi-band and wideband operation of antenna. Reconfigurable antenna has a potential to add some functionality to mobile communication. A reconfigurable antenna is another solution to achieve multiple bands by switching ON Slot antenna - Wikipedia

Reconfigurable Wide Bandwidth Using Novel Extraction ... The entire approach is folded into four different designs. The first design proposes a monopole antenna where asymmetric flower type corners and mushroom shape encloses by T-slot is cut on the patch. This new shaped antenna covers wide impedance bandwidth of about 14.5 GHz within range from 21.5 to 36 GHz. Reconfigurable C and Ku band antenna Using Duelpatch an UWB antenna for multiband applications could effect unwanted emissions in the transmission mode. In this project, a single-feed reconfigurable multiband antenna with two patch elements on a planar structure is proposed. Two C-Slots are employed on the patch elements for excitation of the multi-band mode. RECONFIGURABLE SLOT ANTENNAS WITH CIRCU- LAR POLARIZATION C ... Abstract|A new design for circularly-polarized (CP) slot antennas is flrst described. The antenna is a combination of a shorted square-ring slot and an L-shaped linear slot, and its CP operation frequency can be easily tuned under the condition that the slot area is unchanged. Based on the CP design, two reconflgurable slot antennas are then ... DESIGN AND ANALYSIS OF FREQUENCY RECONFIGURABLE ANTENNA FOR ...
