A dual-frequency and dual-polarization antenna design for long term evolution applications

摘要: A dual-frequency and dual-polarization antenna design is proposed for long term evolution (LTE) applications. The achieves an impedance bandwidth of 45% (658–1070 MHz) at the low-frequency band 52% (1.643–2.8 GHz) high-frequency with more than 6 dBi gain covering most LTE bands. Mutually orthogonal polarizations are also achieved through proper placement radiators making it possible multi-input-multi-output (MIMO) mode operation. has a physical size 0.698λ o × 0.233 λ being wavelength 698 MHz.
