Abstract :
A ±45° polarized wideband slot array antenna is proposed for active antenna system (AAS). The proposed array has a planar structure that integrates all the elements on a single substrate. Metal columns are used to reduce the coupling between adjacent elements. A prototype of a 2 × 2 array antenna is fabricated and measured. The measured results show that the proposed array covers the bands LTE2300 (2300-2400 MHz) and LTE2500 (2500-2690 MHz), and the polarization isolation is higher than 30 dB while the coupling between elements is less than -22 dB.
