A dual‐functional active frequency selective surface (AFSS), which integrates two independent and dividable functions, is presented in this article. The proposed structure consists of two orthogonally arranged metallic layers, separated by a thin dielectric layer. Different active devices, including varactor diodes and PIN diodes, are loaded on top and bottom metallic layers, separately. Thus, the frequency tuning function for transverse magnetic waves and the electromagnetic switching function for transverse electric waves can be attained, respectively, by controlling the working states of these active components. In addition, a novel feeding configuration is designed to mitigate the negative impact of the bias network and provide parallel feeding topology simultaneously. Detailed equivalent circuit models for different polarizations and states are constructed to characterize the AFSS structure. Finally, a prototype of the proposed structure is fabricated and measured for verification, and the experimental observations agree well with the simulated results. This dual‐functional AFSS could be an important step toward multifunctional AFSSs that are endowed with more than two electromagnetic functions.

“…Compared with conventional antennas, microstrip patch antennas have the advantages of light weight, low profile, low cost, easy manufacture, and so on. 1 However, the conventional microstrip patch antennas have the disadvantage of narrow bandwidth, which limits their application. In order to overcome the inherent narrow bandwidth of the conventional microstrip patch antennas, a few methods have been advanced by some scholars in the past decades.…”

A novel singly differentially‐fed microstrip patch antenna (DFMA) is proposed, which is composed of a radiating patch, a differentially‐fed network with a twin antisymmetric miniaturized baluns and a ground plane for unidirectional radiation. In the differentially‐fed network, the signal is coupled to the two feedlines on both sides by the two miniaturized baluns. The radiating patch is excited by the coupling feed sheet located below the radiating patch, and the coupling feed sheet is connected to the upper end of the feedline. The lower end of the feedlines is connected to the ground plane, and there is a slot on the ground of the feeding network. Due to the existence of coupling feed sheet and slot, a second nonradiating resonant is achieved, and a wideband property is obtained. Finally, the prototype of the antenna is fabricated and studied experimentally. Simulated and measured results show that the impedance bandwidth of the antenna is 30.3% (1.71‐2.32 GHz) for S11 < −10 dB. Besides, a stable symmetric radiation pattern is obtained with gain around 9.6 dB and cross‐polarization less than −21 dB, which demonstrates the designed antenna has the property of wideband, high gain and low cross polarization.
