Bandwidth Enhancement of a Broadband Dual-Polarized Antenna for 2G/3G/4G and IMT Base Stations

Bandwidth Enhancement of a Broadband Dual-Polarized Antenna for 2G/3G/4G and IMT Base Stations

The bandwidth (BW) of a broadband dual-polarized antenna is enhanced for 2G/3G/4G systems and international mobile telecommunications services. The broadband dual-polarized element is a four-leaf clover antenna. By introducing a U-shaped slot to each leaf of the four-leaf clover and a parasitic elem...

Zusammenfassung:The bandwidth (BW) of a broadband dual-polarized antenna is enhanced for 2G/3G/4G systems and international mobile telecommunications services. The broadband dual-polarized element is a four-leaf clover antenna. By introducing a U-shaped slot to each leaf of the four-leaf clover and a parasitic element of four disks above the dual-polarized element, the BW enhancement is achieved. It is shown by simulation and experiment that the BW enhanced dual-polarized antenna achieves a BW of 67% (1.39-2.8 GHz) for reflection coefficients
