Abstract
The designs of conformal antenna and its array usually need to combine with different carrier structures. As for cone or cylindrical carrier, through using of invasive weed optimization (IWO), the conformal array should be the optimized design as the antenna installation space requirements of cylindrical carrier; through adopting the antenna unit miniaturization method, it designs out a conformal antenna and makes it easier to be installed and the omnidirectional circular polarized beam is also realized. As for unmanned aircraft carrier, it designs out the low profile of conformal vertical polarization antenna unit; through using the electric field integral equation (EFIE) and electric/magnetic current combined-field integral equation (JMCFIE) and multilevel fast multipole algorithm (MLFMA), it analyzes the two different characteristics of unmanned aircraft carrier on the influence of antenna performance. The results obtained through experiments and JMCFIE analysis are in good agreement; according to unmanned aircraft carrier, it also designed out the antenna in X/K-band spectrum; through IWO, the antenna array is optimized; the test results show that the array scanning angle can reach the corresponding beam direction.
Highlights
The military requirements of conformal antennas can be summarized as follows
The other usually adopts glass fiber reinforced plastic, which can be seen as media carriers. It carried out the research based on two different features of unmanned aircraft carrier effects on the performance of the vertical polarization antenna unit; UAV carrier with carbon fiber material is studied in the paper
As for cone or cylinder carrier, it first adopts the AEP and invasive weed optimization (IWO) to make optimization design on the traditional square patch antenna array; the related processing and testing on the designed antenna are performed, which illustrates the AEP combined with the comprehensive application of conformal array IWO and their excellent performance
Summary
The missile conformal antenna is designed for the guided missile based on a GPS-guided system. It can be seen that, for different application requirements, the antenna in the vehicle platform will be different, so in the paper, it focuses on research and analysis of conformal antennas based on cylindrical carrier and the unmanned aircraft carrier. Through elliptic cylinder FDTD algorithm, Mohammad et al analyzed conformal patch antenna, and its results are coincided well with the results obtained through fullwave simulation software HFSS [6,7,8]; Heckler et al adopted discrete mode matching methods to analyze the conformal microstrip antenna. Software HFSS to analyze irregular medium on the surface of the conformal antenna array [14]; the method of thin dielectric for conformal antenna is analyzed in Hou Luping’s master’s thesis based on the medium carrier [15]. As for conformal arrays, because the complexity of the carrier and the location of the antenna unit are different, the irregularity of the array and the direction of each antenna unit in the array are different, so it is difficult to use the matrix theory and some conventional analytic methods to synthesize it
