A non-uniform collinear dipole array for sub-6 band

In the fifth-generation (5G) wireless communications, due to advantages such as wide range and low cost, sub-6 frequency band is widely used. It a challenge develop antennas for base stations which are band, high gain compact. this paper, center-fed collinear antenna array with compact size developed based on turnstile antenna. Non-uniform dipole has been used achieve broadband so that disadvantages of series can be improved. The bandwidth significantly increased compared uniform antennas. Wider directivity 35% provided by non-uniform array. proposed omnidirectional radiation applications. reached 20.7% better than traditional fed
