A low-profile wideband stacked tightly coupled patch array (TCPA) with parasitic strips is presented in this brief. Analyzed via a two-port network and originated from the traditional TCPA, the evolution of TCPA element is conducted by gradually introducing superstrate, parasitic patch and parasitic strips, and the ultimate one can exhibit an impedance bandwidth of 131.9%. Then, employing a practical feeding structure enables the implementation of the element to operate in a 102.0% band. Eventually, a <inline-formula> <tex-math notation="LaTeX">6\times 6 </tex-math></inline-formula> prototype is constructed to verify the design correctness, and the results reveal that the working band is 2.4-6.8 GHz (94.6%) with VSWR less than 2, while the TCPA can respectively scan from −60° to 60° and from −40° to 40° in the E-plane and H-plane with VSWR<3. On account of its compact size, wide band, ascendant radiation characteristics and scanning performance, the proposed TCPA is promising in the application of large-scale arrays and communication systems.
