Abstract

─ A partially reflective metasurface (PRMS) structure is proposed for dual-polarized dipole antenna with a high gain and wide broadband. Stable radiation patterns are realized by using quadrilateral bottom reflector. The phase bandwidth of PRMS structure reflection presented in this paper matches well with the antenna operating bandwidth. The gain of the dualpolarized antenna is improved to 10.2dBi at 1.8GHz by adjusting the size and height of PRMS structure. Meanwhile, the bandwidth is expanded (61.2%). Measured result demonstrates that the antenna has a stable beamwidth which is desirable in base station applications. Furthermore, the designed antenna can be used for communication in complex environment because of its excellent performance. Index Terms ─ Dual-polarize, high gain, partially reflective metasurface (PRMS), quadrilateral bottom reflector.

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 The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics.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.
