Design and Analysis of Enhanced Bandwidth Slotted Logarithmic Spiral Patch Antenna for 5G Communication

This paper introduce a design of a Logarithmic-Spiral Patch Antenna (LSPA) tailored for Fifth Generation (5G) communication applications. Resonating at a core frequency of 28 GHz, the proposed antenna exhibits remarkable performance characteristics. Its bandwidth spans from 26.2 to 30.6 GHz. These qualities make it suitable for many 5G communication systems that require high-frequency functioning. At 28.10 GHz, Reflection Coefficient (S11) is 16.061, which is the antenna's performance indicator. At the center frequency, the Voltage Standing Wave Ratio (VSWR) is also measured at a very favorable value of 1.70. The LSPA design is successful in providing low signal loss and great efficiency within the designated frequency as seen by these superior S parameter and low VSWR value. The LSPA design is physically small, with dimensions of 6 mm in length, 4.5 mm in breadth, and just 0.254 mm in thickness. This small form factor makes it possible to develop compact, integrated devices that are also simple to install and integrate into contemporary communication networks. The LSPA is constructed on a Rogers RT Duroid 5880 substrate material to preserve structural integrity and high-frequency performance. The antenna's longevity and capacity to function efficiently in the millimeter-wave frequency spectrum are guaranteed by the substrate material selection. In summary, this study introduces a unique Logarithmic-Spiral Patch Antenna with wide bandwidth, superior S parameters, low VSWR, and small physical dimensions. The antenna is a good choice for high-speed and high-capacity wireless communication systems due to its eligibility for 5G communication and its central frequency of 28 GHz, which supports the development of next-generation connectivity.
