Abstract	A new method for pattern reconfigurable antenna (PRA) design is introduced on the basis of a two-element dipole array model in this communication. Firstly, a two-element dipole array loaded with varactor diodes is analyzed in detail. The two dipoles of the array are folded to form a square and the reconfigurable pattern characteristics of the array can be still explained by the phased array theory. And then, based on the two-element dipole array model, a patch top-loaded monopole antenna is proposed to design the PRA (denoted as PTMPRA). Applying the field equivalence principle, the antenna radiation can be analyzed with two couples of magnetic dipoles. The phase of the magnetic dipoles may be adjusted by the loaded varactor diodes, and the antenna can reconfigure the patterns in two orthogonal planes. The antenna is fabricated and measured. The studies validate that the new method for designing pattern reconfigurable patch antenna is simple and efficient.
