Abstract :

In this paper, the aim is to cover LTE, band by presenting a new design of multi-input / multi-output radiators an acceptable radiation pattern and gain. The design process in this research is a bipolar radiator with a physical size of 1.6 × 40 × 40 mm3, when the port number one is excited, the frequency bands are 0.78-1.07, 2.01-2.67, 3.74-4.7.0.77-7.14, 9.38-10.10 GHz forsecond port. Based on the results, the structure has a good isolation between the two ports. By applying a spiral slit in the span of one and one inverted slit and creating a diagonal state in the corners of the element in the second span of circular polarization in the bands of 0.59-1.01, GHz in the first port in the left direction and 0.58-1.45 GHz is obtained in the second port in a right-handed. This scheme with its charaterestics is good candidate for mobile applications & IOT.
