Abstract
A broadband omnidirectional low-profile antenna with dual polarization for 4G MIMO indoor applications is presented. The dual polarized antenna is a combination of a low-profile monocone antenna for vertical polarization (VP) and a broadband dipoles array for horizontal polarization (HP). The low-profile monocone antenna achieves an impedance bandwidth of 103% from 0.87 GHz to 2.75 GHz, covering the GSM900/1800/1900/UMTS and LTE2300/2500 bands. The broadband dipole array provides an impedance bandwidth of 57% from 1.59 GHz to 2.87 GHz, including PCS, UMTS/LTE, Bluetooth, ISM, and WLAN bands. The isolation between the two antennas is greater than 38 dB in the whole bands. The profile of the proposed antenna is 78.6mm.
