摘要

─以微带贴片天线为基础，设计了一种圆柱形共形8×8阵列天线，该天线采用t形功率分配器实现64个馈电通道。仿真结果表明，平面阵列天线的峰值增益可达24.8dB，而圆柱共形天线的峰值增益在φ =0°和φ =90°时分别下降1.2dB和1.7dB。和主声束偏转方向分别为0°和4°。测量结果表明，处理后的目标性能与仿真结果接近。与圆柱共形后，峰值增益为23.5dB，波束偏转为4°，验证了所设计圆柱共形阵列天线的可行性。索引项─阵列天线，共形天线，微带贴片。

Design of Cylindrical Conformal Array Antenna based on Microstrip Patch Unit

─ Based on microstrip patch antenna, a cylindrical conformal 8×8 array antenna is designed, which uses a T-shaped power divider to realize 64 feed channels. The simulation results show that the peak gain of planar array antenna can reach 24.8dB, while the peak gain of cylindrical conformal antenna decreases by 1.2dB and 1.7dB in phi=0° and phi=90° respectively. And the main beam direction deflects by 0° and 4° respectively. The measurement results show that the performance of the processed object is close to the simulation. After conformal with cylinder, the peak gain is 23.5dB, and the beam deflection is 4°, which verifies the feasibility of the designed cylindrical conformal array antenna. Index Terms ─ Array antenna, conformal, microstrip patch.

期刊介绍： The ACES Journal is devoted to the exchange of information in computational electromagnetics, to the advancement of the state of the art, and to the promotion of related technical activities. A primary objective of the information exchange is the elimination of the need to "re-invent the wheel" to solve a previously solved computational problem in electrical engineering, physics, or related fields of study. The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics. All papers are refereed. A unique feature of ACES Journal is the publication of unsuccessful efforts in applied computational electromagnetics. Publication of such material provides a means to discuss problem areas in electromagnetic modeling. Manuscripts representing an unsuccessful application or negative result in computational electromagnetics is considered for publication only if a reasonable expectation of success (and a reasonable effort) are reflected. The technical activities promoted by this publication include code validation, performance analysis, and input/output standardization; code or technique optimization and error minimization; innovations in solution technique or in data input/output; identification of new applications for electromagnetics modeling codes and techniques; integration of computational electromagnetics techniques with new computer architectures; and correlation of computational parameters with physical mechanisms.
