英文摘要： Conical beam antennas and array are widely adopted in radar, vehicle satellite communication, detection and guidance, wireless personal area network and new generation WLAN. There are still many challenging problems in realization and fast analysis of the conical beam antenna array possessing high-gain conical beam, frequency and phase scanning conical beam and reconfigurable conical beam. In this proposal, high-gain conical beam antenna array with specific flare angle can be realized by using the conical beam antenna as the element of the array and taking advantage of grating lobes, which is a novel solution different from current schemes. In order to achieve the reconfigurable performance, a new concept of grating lobe frequency and phase scanning will be employed. Frequency selectivity and spatial selectivity of the FSS cover will be integrated simultaneously to implement multi-frequency high-gain Fabry-Perot (FP) conical beam antenna. Flare angle of the FP conical beam antenna and array will be controlled by using electronic controlled FSS. According to the characteristics of the conical beam antenna, hybrid higher-order body of revolution method of moment (BoRMoM) and mode matching (MM) will be developed to accelerate the analysis and optimization design of the conical beam antenna loaded with superstrates
