“…Compared to traditional antenna [2,3], microstrip antennas [8][9][10] have advantages of low profile and light weight, and allow easy integration with surface mount devices, which are more promising and flexible for COCO antenna design,. Based on the COCO antenna theory and mature processing technology of microstrip antenna [11][12][13][14], a novel kind of COCO antenna is proposed in S band in this paper. The shape of the elements is simplified.…”

In this paper, a kind of omnidirectional microstrip coaxial collinear (COCO) antenna array is designed, fabricated, and tested. The antenna is fabricated by standard printed circuit board technology (PCB), with overall dimension of 300×30×0.8mm³. The measured bandwidth of the antenna is about 4% with VSWR less than 1.4. The antenna has stably omnidirectional H-plane radiation patterns in the whole effective bandwidth, while the measured maximum gain reaches 4.85dBi at the highest frequency. Good agreement between the simulations and measurements is observed.

“…Researchers proposed a series of special-shaped antennas [1][2][3], which can achieve broad bandwidth but will lead to pattern split and poor omnidirectivity. Although coaxial collinear antennas can achieve high gain and omnidirectivity, their bandwidth is narrow [4,5], too, because their terminals are short circuited and thus have a resonant configuration. The antennas in [6][7][8][9] all have narrow bandwidth and low gain per wavelength, which is not conducive to antenna miniaturisation.…”

A novel coplanar waveguide planar antenna, which is broadband, high‐gain and omnidirectional, is proposed and analysed. The antenna radiation efficiency is improved by introducing a kind of monopole radiator as a non‐consumption radiated terminal load. The out‐of‐roundness of the antenna's H‐plane (x–z plane) is decreased by introducing horizontal stubs as non‐effective radiated loads. The simulated and experimental results indicate that the operating band of the proposed antenna is 4.65–5.61 GHz with a reflection coefficient less than − 10 dB (relative bandwidth 18.7%), the out‐of‐roundness of the radiation pattern in the horizontal plane (H‐plane or x–z plane) is less than 1.5 dB and the maximum gain achievable in the elevation plane (E‐plane or x–y plane) is more than 5.0 dB in the operating band. The pattern bandwidth well matches the impedance bandwidth. Moreover, the gain per wavelength of the novel antenna exceeds 3.0 dB, which is beneficial for antenna miniaturisation.
