Abstract

─ In this communication, a compact design of a reconfigurable antenna array operating in the band IEEE 802.11a is presented. The proposed antenna array contains four radiating elements excited by a hybrid parallel-series-feed network. The hybrid feed technique is used to avoid the main beam squint due to frequency changes compared to series and parallel array feed topologies. Each of the four radiating elements consists of straight narrow strip inductor in parallel with an interdigital capacitor. The antenna resonant frequency is electronically controlled by placing PIN diodes switches at the resonant element's inputs. The antenna permits reconfigurable switching frequency bands between 5.25 and 5.82 GHz. The results of the return loss and pattern radiation are shown. The size of the whole antenna structure is about 64 × 18 mm and can potentially be used in wireless systems. Index Terms ─ Antenna array, hybrid feed, reconfigurable, miniaturized.

用于WLAN应用的紧凑型可重构天线阵列设计

在本通讯中，提出了一种在IEEE 802.11a频段工作的可重构天线阵列的紧凑设计。所提出的天线阵列包含四个由并联-串联-馈电混合网络激励的辐射单元。与串联和并联阵列馈电拓扑结构相比，混合馈电技术可以避免由于频率变化引起的主波束斜视。四个辐射元件中的每一个都由与数字间电容并联的直窄带电感组成。天线谐振频率是通过在谐振元件的输入端放置PIN二极管开关来电子控制的。该天线允许在5.25和5.82 GHz之间的可重构切换频段。给出了回波损耗和方向图辐射的计算结果。整个天线结构的尺寸约为64 × 18 mm，可用于无线系统。索引术语─天线阵列，混合馈电，可重构，小型化。

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 The ACES Journal welcomes original, previously unpublished papers, relating to applied computational electromagnetics.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