“…The use of EBG structures for mutual coupling reduction has been widely investigated, and various types of EBG structures have been proposed for this application [15]. The concept of EBG arises from the optical domain, where photonic crystals can forbid the propagation of light or allow it in certain directions.…”

This paper presents the simultaneous application of Minkowski fractal geometry and EBG structures for mutual coupling reduction in microstrip array antennas for the first time. In this approach, a modified version of Minkowski fractal geometry is applied on the patch elements, and at the same time 1D electromagnetic bandgap (EBG) structures, composed of 4 EBG elements, are placed between the array elements in a very close distance. Unlike many other coupling reduction methods, which have at least one of the issues of gain reduction or complex fabrication, the proposed method does need any via or double-sided etching and slightly increases the gain of the antenna, while an excellent reduction level of 22.7 dB has been achieved. To verify the concept, 2 array antennas with the spacing of λ 0 and λ 0 /3 were fabricated and tested, showing very good agreement between predicted and measured results.

“…The EBG antenna design and performance were discussed in Ref. 11 however the design will be re-discussed here for ease of reference. It comprises a 2 × 2 array of EBG mushroom unit cells on an FR4 substrate (dielectric constant 4.2, thickness 1.55 mm, and a loss tangent 0.02) shown in Figure 1A.…”

“…Although there are several such models for microstrip antennas, there is a dearth of similar models for electromagnetic bandgap (EBG) antennas reported fairly recently. [10][11][12] In this letter, a novel equivalent circuit model is developed for an aperture coupled EBG antenna, resonant at the ISM 5.8 GHz frequency band which was proposed in Ref. 11 The model is derived from the current flow analysis of the antenna's operation and predicts a −10 dB impedance bandwidth of 0.42 GHz (7.3%), which is validated against the simulated impedance bandwidth of 0.50 GHz (8.6%) and measured impedance bandwidth of 0.51 GHz (8.8%).…”
