The invention discloses a small-size beam controllable patch antenna based on a reconfigurable parasitic element, and the antenna comprises an E-shaped main radiation patch, a left parasitic patch anda right parasitic patch. Through employing a CSRR structure, the antenna reduces the electrical length of a parasitic patch, and facilitates the miniaturization of the parasitic patch.

The combination of different states ofthe left and right parasitic elements can enable the main lobe direction of a radiation beam of the antenna to be switched among 0 degree, -30 degree, and 30 degrees, thereby achieving the beam controllable performance of the antenna, and effectively enlarging the beam scanning range of the antenna. The antenna employs the coaxial feed E-shaped main radiation patch and introduces an air layer structure between two dielectric substrates, thereby effectively enlarging the work bandwidth of the antenna. The antenna is high in gain, is high in front-to-rear ratio, and is low in profile.
