“…Another typical ultra‐wideband dual‐polarisation antenna based on tapered slot technique is presented in [10, 11]; however, it has the disadvantages of high profile and low isolation and is not preferred in base station antenna designs. Dual‐polarised printed slot antenna is presented in [12, 13]. Although sufficiently high isolation and very low cross‐polarisation are achieved, the impedance bandwidths of them are still not wide enough.…”

A broadband cross‐dipole with high isolation and low cross‐polarisation for base station applications in mobile wireless communications is presented in this study. By skillfully utilising the strong mutual coupling between the two dipoles, very good impedance match, sufficiently high isolation and low cross‐polarisation can be achieved simultaneously. The measured results show that a more than 54% impedance bandwidth for standing wave ratio (SWR) < 1.5 from 1.695 to 2.95 GHz is achieved, within which the isolation is larger than 35 dB and the cross‐polarisation is less than −34 dB. As a desirable advantage, the input impedance of the antenna can be changed within certain limits by properly adjusting the configuration, thus the antenna can be fed directly by 50‐Ω coaxial cables without the aid of impedance transformers. Particularly, besides the designing and the optimising work, the mechanisms for high isolation and low cross‐polarisation as well as the method to adjust the input impedance are also discussed from a new point of view, which are also appropriate for other cross‐dipole with the similar patterns.

Abstract-A novel coax-fed wideband loop antenna loaded with rectangular patches and U-shaped elements is presented and studied. By inserting a pair of rectangular patches inside the strip loops and employing a pair of U-shaped elements as the parasitic resonators, two additional resonances are excited and a good performance of bandwidth enhancement can be obtained. The measured results indicate that the impedance bandwidth (VSWR≤2) is about 87.1% from 1.58 to 4.02 GHz, which covers the required operating bands of DCS1800
