Collinear Super Turnstile Antennas for 5G Sub-6 Base Station

In the fifth-generation (5G) wireless communications, due to the advantages such as wide range and low cost, sub-6 frequency band is widely used. It is a challenge to develop the antennas for sub-6 base stations which are wide band, high gain and compact. In this paper, a center-fed collinear antenna array with a compact size is developed based on the super turnstile antenna. The antenna array works at 4.7 GHz, omni radiation pattern is obtained with the average gain of 8 dBi at a wide bandwidth of about 13%.
