设计了一种适用于固定频率和可重构频段的低剖面紧凑型印刷天线。该天线由一个主贴片、四个子贴片和一个接地层组成，可为不同的无线系统产生0.92、1.73、1.98、2.4和2.9 GHz的五个频带。对于固定频率设计，仅使用天线的一个参数，就可以分别在18.78%、22.75%、4.51%、11%和8.21%的宽范围内独立地调整和设置五个单独的频带。通过在每个子贴片输入端放置变容二极管，可以在宽范围内独立控制四个频带，并且天线具有可重构设计。0.92、1.73、1.98和2.9 GHz四个频带的可调谐范围分别为23.5%、10.30%、13.5%和3%。利用计算机仿真研究了固定和可重构设计。为了验证模拟结果，制造了两种设计并测量了原型。结果表明，模拟和测量结果之间有很好的协议。
This paper presents the design of a low-profile compact printed antenna for fixed frequency and reconfigurable frequency bands. The antenna consists of a main patch, four sub-patches, and a ground plane to generate five frequency bands, at 0.92, 1.73, 1.98, 2.4, and 2.9 GHz, for different wireless systems. For the fixed-frequency design, the five individual frequency bands can be adjusted and set independently over the wide ranges of 18.78%, 22.75%, 4.51%, 11%, and 8.21%, respectively, using just one parameter of the antenna. By putting a varactor (diode) at each of the sub-patch inputs, four of the frequency bands can be controlled independently over wide ranges and the antenna has a reconfigurable design. The tunability ranges for the four bands of 0.92, 1.73, 1.98, and 2.9 GHz are 23.5%, 10.30%, 13.5%, and 3%, respectively. The fixed and reconfigurable designs are studied using computer simulation. For verification of simulation results, the two designs are fabricated and the prototypes are measured. The results show a good agreement between simulated and measured results.
