A Small-Size Wideband Magneto-Electric Dipole Antenna With Circular Parasitic Element and Short Pins

A small-size magneto-electric dipole antenna is introduced in this article. The proposed antenna contains a ellipse dipole with two short pins and a split circular parasitic element, which contributes to a miniaturized volume size (0.45 λL×0.45λL×0.21λL, λL is the free-space wavelength of the lowest frequency) and good impedance matching bandwidth covering 2.5-7.5 GHz for VSWR<; 2. In addition, the simulation results indicate that the proposed antenna has achieved a gain within 5.3-9.9 dBi for 3-7.5GHz, 1.43-4.85 dBi for 2-2.5 GHz, and low cross-polarization over the working frequency.
