摘要：
In this paper, several multi- uniform circular array (M-UCA) antennas are designed at 3GHz. Their transmission characteristics especially in phase and amplitude distribution of electric field component are discussed. The UCA antenna carrying orbital angular momentum (OAM) consists of 12 dipole elements and a circular ground with 1/4 wavelength behind the array. By placing two UCA with different angles at a certain distance some special phenomena are observed. The vortex electromagnetic waves produced by the UCA influence each other seriously and the interaction between the UCA antennas cannot be neglected. The spiral phase characteristics are damaged. The influence factors such as angle between the UCAs are analyzed.
