This article is focusing on a technical design of superstrate layer using 3x3 unit cells to enhance the antenna gain, operating at the center frequency of 2.50 GHz. In fabrication of the proposed antenna, a microstrip antenna is fed by a 50Ω-SMA 3.50 mm connector, and the superstrate is designed using 9 octagon ring-shaped unit cells, which are integrated to form a meta-surface antenna (MS antenna). A prototype antenna is manufactured on an FR4 substrate material with a relative permittivity (ԑr) of 4.3 and a height of 1.6 mm. The prototype antenna is great matched to achieve |S11| of -31.55 dB, exhibits a gain enhancement of >2.0 dBi and achieves a maximum gain of >6.0 dBi. Additionally, the proposed design has been fabricated to validate |S11|, gain, and radiation patterns as comparing with the simulated results that will be presented. Evidently, the simulated results reasonably align with the experimental findings.

W artykule skupiono się na projekcie technicznym warstwy superstratnej wykorzystującej ogniwa elementarne 3x3 w celu zwiększenia zysku anteny, pracującej na częstotliwości środkowej 2,50 GHz. Podczas produkcji proponowanej anteny antena mikropaskowa jest zasilana przez złącze 50 Ω-SMA 3,50 mm, a superstrata została zaprojektowana przy użyciu 9 ośmiokątnych ogniw elementarnych w kształcie pierścienia, które są zintegrowane, tworząc antenę metapowierzchniową (antena MS). Prototypowa antena jest produkowana na podłożu FR4 o przenikalności względnej (ԑr) wynoszącej 4,3 i wysokości 1,6 mm. Prototypowa antena jest doskonale dopasowana do osiągnięcia |S11| -31,55 dB, wykazuje wzmocnienie wzmocnienia >2,0 dBi i osiąga maksymalne wzmocnienie >6,0 dBi. Ponadto proponowany projekt został opracowany w celu sprawdzenia |S11|, wzmocnienia i wzorców promieniowania w porównaniu z symulowanymi wynikami, które zostaną zaprezentowane. Najwyraźniej symulowane wyniki są w rozsądny sposób zgodne z wynikami eksperymentów.
