Abstract

This letter presents a low-profile, multilayer planar microstrip patch antenna (MPA) array with cross-band frequency reconfigurability. The compact single-port MPA element, sized 7.8 mm × 7.8 mm × 3 mm, operates in the C and K_u bands and comprises a driven patch surrounded by five parasitic patches interconnected via four PIN diodes for frequency switching. A compact interelement spacing combined with a novel Γ-shaped coupled-feed structure is utilized to harness mutual coupling, thereby extending the attainable frequency reconfiguration range. An 8 × 8 antenna array was fabricated and experimentally characterized, demonstrating central operating frequencies of 4.9 GHz and 17.8 GHz in two distinct reconfigurable states. The design achieves a frequency reconfiguration ratio of 4.06:1, covering a total frequency reconfigurability span of 14 GHz across noncontiguous bands. Measured results show strong agreement with simulations, validating the proposed concept.

一种简单紧凑的跨带可重构微带贴片天线阵列

这封信提出了一个低轮廓，多层平面微带贴片天线（MPA）阵列，具有跨频带频率可重构性。紧凑的单端口MPA元件，尺寸为7.8 mm × 7.8 mm × 3mm，工作在C和Ku波段，包括一个驱动贴片，周围有五个寄生贴片，通过四个PIN二极管相互连接，用于频率切换。紧凑的元件间距与新颖的Γ-shaped耦合馈电结构相结合，利用相互耦合，从而扩大了可实现的频率重构范围。制作了一个8 × 8天线阵列并进行了实验表征，在两种不同的可重构状态下，其中心工作频率分别为4.9 GHz和17.8 GHz。该设计实现了4.06:1的频率重构比，覆盖了14 GHz的非连续频带的总频率重构范围。测量结果与模拟结果非常吻合，验证了所提出的概念。

期刊介绍： IEEE Antennas and Wireless Propagation Letters (AWP Letters) is devoted to the rapid electronic publication of short manuscripts in the technical areas of Antennas and Wireless Propagation. These are areas of competence for the IEEE Antennas and Propagation Society (AP-S). AWPL aims to be one of the "fastest" journals among IEEE publications. This means that for papers that are eventually accepted, it is intended that an author may expect his or her paper to appear in IEEE Xplore, on average, around two months after submission.
