ABSTRACT:

In this talk, novel reconfigurable antennas and arrays will be discussed. There are three main
possibilities for the reconfiguration: frequency reconfiguration, polarization reconfiguration, and
radiation pattern reconfiguration. Antenna reconfiguration can be realized by implementing RF switches
with the radiating elements in particular arrangements, ground plane reconfiguration and control of
the multiple radiating modes. Different antenna elements leading to frequency and radiation pattern
reconfiguration will be presented such as compact spiral loaded planar dipole antenna, planar loop
antenna with MIMO implementation, spirograph planar monopole antenna, and planar Yagi-Uda
antenna, etc. By controlling amplitude and phase of the radiating modes in a multiple mode antenna
structure, radiation pattern beams can also be reconfigured. Examples of such radiating elements are
multiple modes microstrip patch antennas, multiple mode feedhorns, and combination of different
collocated antenna elements simultaneously generating desired radiating modes, etc.
