A multiple resonant microstrip patch heart shape antenna for satellite and Wi-Fi communication

Microstrip antennas are in high demand because of their low profile and lightweight, leading to a recent surge in the need for low-profile antennas for wireless communications. Due to the growing significance of wireless communication in recent years, very inventive research has been conducted. By extending current trends, microstrip antennas provide solutions for various problems. A heart-shaped microstrip patch antenna was introduced in this proposed methodology. The shape of the microstrip patch antenna dimensions are 29 mm × 32 mm × 1.6 mm. The FR-4 substrate material is used in a heart-shaped antenna with a tangent loss is 0.02 and a dielectric constant is 4.4. the high-frequency structure simulator software is used to design and implement a heart-shaped microstrip patch antenna. The patch features four inverted L-shaped slots and one S-shaped slot to provide multiple resonant frequencies for satellite and WI-FI connectivity. At 0.9 GHz, 1.4 GHz, and 2.45 GHz, the antenna is in use. Its two lower working frequency bands show good symmetry in its radiation patterns. The antenna covers a range of frequencies, including WLAN (5.15–5.35 GHz), 5G (5.725–5.825 GHz), TD-LTE (B-TrunC) (1.447–1.467 GHz), LTE42/43 (3.4–3.8 GHz), WiMAX (3.3–3.8 GHz), 5G band n78 (3.4–3.8 GHz), and more bands. Furthermore, the measurement and construction of the prototype are finished. The results show that its gains at 0.9 GHz, 1.4 GHz, and 2.45 GHz are − 32.2 dBi, − 18.8 dBi, and − 19.1 dBi.
