Advanced T-shaped smart antenna architecture for improved mobile network efficiency

Wireless body area networks are becoming increasingly common as the use of wireless networks and other electrical devices increases. A Wearable Patch antenna is used to improve the performance of different WBAN applications. Wireless body area network (WBAN) technology is used to construct a low-profile wearable microstrip patch antenna for continuous monitoring of human vitals such as blood pressure, pulse rate, and temperature. The antenna operates in the ISM band at frequencies of 2.5 GHz, 3.5 GHz, 4.5 GHz, and 5.5 GHz. The FR4 substrate has a dielectric constant of 4.4 and is 1.6 mm thick. The proposed antenna is designed to outperform current wearable antennas in terms of reflection coefficient, VSWR, gain, and radiation pattern. The antenna has a maximum reflection coefficient of −2.72 dB and a minimum reflection coefficient of −18.78 dB, with a gain of 7.8 dB maximum and 4.2 dB minimum with a VSWR of 1.75. Other antenna field properties, such as 2D and 3D gain and radiation pattern, have been calculated. The High-Frequency Structure Simulator [HFSS] is used to design and simulate the proposed antenna. The impedance bandwidth, radiation pattern, and observed gain of the suggested small antenna for multiband operation have all been examined computationally and experimentally. The current distribution of the suggested antenna may be effectively expanded using a T-shaped antenna, and the antenna’s dimensions are considerably tailored to acquire more resonant frequencies within the needed frequency range. Compact antennas and effective multi-band radiation are both required for wireless communications. Nowadays, dual-frequency antennas are the favored option. Typically, WiMAX applications employ microstrip patch antennas, which provide circular polarization. The issues brought on by poor transmitter-to-receiver synchronization may be rectified using circularly polarized antennas. The major goal is to increase the operating bandwidth of an at its corners truncated single-feed square patch. At these frequencies, the simulation and measurement outcomes are contrasted.
