In this paper, the isolation improvement method of mobile terminal antenna is studied. For the symmetrically designed antennas, the isolation is optimal when the impedances of the common mode (CM) and the differential mode (DM) are equal. Based on this analysis method, a method is proposed to improve the isolation by connecting simultaneously inductance and capacitance in series between two adjacent inverted-F antenna ground points in the case of tight coupling. First, the isolation without and with series inductance and capacitance is compared by the xfdtd simulation software. Secondly, the proposed antenna was manufactured then the isolation and return loss were measured. The experimental results show that this method could improve the isolation

The paper proposes an optimization method of the elevation of antenna array based on the analysis of the detection power of radar system from the point of view of radar system design. The method builds the direct relationship between the radar system design and the elevation of the antenna creatively. The elevation is optimized for a typical radar system covering airspace by theoretical derivation and simulation analysis. The elevation obtained by this method can reduce 6.6% of the radar system scale, compared with the vertical array. Meanwhile, the paper simulates the
