yes / This paper presents a compact-size, low-cost smart
antenna with electronically switchable radiation patterns, and
reconfigurable polarizations. This antenna can be dynamically
switched to realize three different polarizations including two
orthogonal linear polarizations and one diagonally linear polarization.
By closely placing several electronically reconfigurable
parasitic elements around the driven antenna, the beam switching
can be achieved in any of the three polarization states. In this
design, a polarization reconfigurable square patch antenna with a
simple feeding network is used as the driven element. The parasitic
element is composed of a printed dipole with a PIN diode. Using
different combinations of PIN diode ON/OFF states, the radiation
pattern can be switched toward different directions to cover an
angle range of 0◦ to 360◦ in the azimuth plane. The concept is
confirmed by a series of measurements. This smart antenna has
the advantages of compact size, low cost, low power consumption,
reconfigurable polarizations, and beams.
