Abstract (en)

[origin: EP3012910A1] A broadband dual-polarization four-leaf clover planar antenna which is applied to the 2G/3G/LTE (4G) systems is described; the antenna includes an antenna radiating unit, a reflecting plate and two feeders. The antenna radiating unit is fixed directly above the reflecting plate via an insulated support structure, and includes a +45° polarized four-leaf clover oscillator and a -45° polarized four-leaf clover oscillator; the four-leaf clover oscillator includes a radiating arm and a microstrip line; the radiating arm being in a four-leaf clover shape is etched on a dielectric substrate, and the microstrip line being used for feeding the radiating arm is also etched on the dielectric substrate. The two feeders are respectively connected with the microstrip lines of the +45°/-45° polarized four-leaf clover oscillators.
