In 5G applications, the antenna system plays a vital role to maintain the efficiency of the signal coverage during transmission. The millimeter-wave (mm-wave) and sub-6 GHz bands are integrated into the new antenna system which is suggested for the 5G handheld devices. The suggested antenna is a single antenna system that covers a 32.4 GHz bandwidth from 5.8 GHz to 38.2 GHz. The intended antenna structure has been obtained by introducing T-Shaped slots in the patch along with presence of parasitic elements on either side. The antenna's FR-4 substrate is developed with dimensions of 30 28 1.6 mm2. The gain varies between 5 and 32 dBi across the operating frequency. The parasitic components are designed and connected with the patch to support the patch's ability to radiate with multiple resonances over a wide operating band. The optimal antenna includes six resonant frequencies 11 GHz, 18.2 GHz, 20.3 GHz, 21.7 GHz, 23.2 GHz, and 27 GHz. During the entire working frequency, the Voltage Standing Wave Ratio (VSWR) is obtained below 2, which signifies well impedance matching. The antenna maintains an efficiency of at least 65 % throughout, making it a strong candidate for 5G devices. The novel antenna geometry with compact size, wide operating band with multiple fruitful resonant frequencies, high gain, good radiation efficiency, omnidirectional stable radiation patterns are the major findings reported in this article. |
