In this paper, a dual circular polarized (CP) spherical conformal antenna array is designed based on a 3D printing framework. The 3D printing technology is employed to simplify the manufacturing process and reduce the cost. There are 23 elements arranged on the hemispherical surface with an optimized distribution. It also has the ability to scan a beam within the hemispherical coverage.
In this paper, an S-band dual circular polarized (CP) spherical conformal phased array antenna (SPAA) is designed. It has the ability to scan a beam within the hemisphere coverage. There are 23 elements uniformly arranged on the hemispherical dome. The design process of the SPAA is presented in detail. Three different kinds of antenna elements are compared. The gain of the SPAA is more than 13 dBi...
The orbital angular momentum (OAM) of the electromagnetic wave is a potential solution to increase the communication capacity. A new OAM antenna structure, which is based on the folded reflectarray antenna, is proposed in this paper. Such an antenna structure overcomes these disadvantages of a traditional OAM antenna, such as large longitudinal size, mismatching between the wave and the dielectric,...
With the development of the integrated phased array, antennas and feeding networks are expected to be integrated together. In this case, the multilayer stacked technique has the advantages of reducing the circuit size and easy to fabricate by Print Circuit Board (PCB) process. In this paper, a complex microstrip feeding network, including a divider, a combiner and a monitoring structure, is employed...
