The frequency bands that the suggested rectangular patch antenna with two parasitic elements operate over the bands 2.35–2.47 GHz, 4.04–5.21 GHz, and 5.54–6.17 GHz. The effects of slits, parasitic components, and a split ring resonator (SRR) on the performance of the antenna are analysed in detail. Important performance indicators are assessed, including return loss, gain, and radiation pattern. At 2.4 GHz, 4.8 GHz, and 5.8 GHz, the observed return loss values are − 17.7 dB, − 25.04 dB, and − 17.24 dB, respectively. These values meet the requirements of 5G applications and yield a maximum gain of 4.54. Many wireless applications, such as the 2.4 GHz Wi-Fi/Bluetooth band, the 5/5.15/5.8 GHz Wi-Fi and Wi-Max bands, the n79 5G spectrum, and the 4.9 GHz WLAN frequency, are well-suited for this multi-resonance antenna. The antenna performs well at all operating bands with a maximum efficiency of 88%.

摘要

The frequency bands that the suggested rectangular patch antenna with two parasitic elements operate over the bands 2.35–2.47 GHz, 4.04–5.21 GHz, and 5.54–6.17 GHz. The effects of slits, parasitic components, and a split ring resonator (SRR) on the performance of the antenna are analysed in detail. Important performance indicators are assessed, including return loss, gain, and radiation pattern. At 2.4 GHz, 4.8 GHz, and 5.8 GHz, the observed return loss values are − 17.7 dB, − 25.04 dB, and − 17.24 dB, respectively. These values meet the requirements of 5G applications and yield a maximum gain of 4.54. Many wireless applications, such as the 2.4 GHz Wi-Fi/Bluetooth band, the 5/5.15/5.8 GHz Wi-Fi and Wi-Max bands, the n79 5G spectrum, and the 4.9 GHz WLAN frequency, are well-suited for this multi-resonance antenna. The antenna performs well at all operating bands with a maximum efficiency of 88%.
