Abstract

The magnetoelectric (ME) dipole antenna is a type of complementary antenna. The basic antenna geometry includes a planar electric dipole and a vertical shorted quarter-wave patch antenna. Traditionally, a proximity coupled feed is utilized to excite the antenna which performs as a combination of an electric dipole and a magnetic dipole. As a result, the antenna exhibits a wide impedance bandwidth, a stable gain, and a stable radiation pattern with low cross-polarization and back radiation levels over the operating frequencies. After the discourse of the fundamental magnetoelectric dipole design, several studies are devoted to antenna height reduction and alternative feed methods. And then some research works, focusing on designing magnetoelectric dipoles with different polarizations, are presented. The magnetoelectric dipole antenna is also modified for the fulfillments of various applications, such as UWB and 60-GHz wireless communications. Other than the magnetoelectric dipole, several other types of complementary antennas are also introduced.
