  • Development of CPW Fed Slot Antenna with CSRR for Biomedical Applications
    Koteswararao Seelam, S. V. Rama Rao, Srinivasa Rao Kandula, Abdul Hussain Sharief, Venkata Reddy Adama, S. Ashok Kumar
    Journal of Circuits Systems and Computers, 2024
    This paper presents a complementary split-ring resonator (CSRR) loaded coplanar waveguide (CPW) fed with a circular shape, miniaturized diamond slot planar monopole antenna. The proposed antenna for healthcare monitoring biomedical applications uses the industrial medical and scientific band. The antenna design and development to implant the human phantom are proposed. The primary goal of this work is to continuously monitor the patient’s ability to detect abnormal conditions as soon as possible as a result of improvements in quality of life. In this case, an antenna design methodology must prioritize features such as miniaturization, increased gain and bandwidth, and biocompatibility. Simulated and measured antenna characteristics for biomedical applications are performed at ISM Band frequency.

    Radio frequency energy harvesting (RFEH) is adopted as a better alternative of energy for powering various wireless sensor networks of a smart city. However, a multiband antenna acquires a greater potential in the RFEH process to enhance the antenna's receiving strength. This work presented a quadband dielectric resonator antenna (DRA) with dual-polarization characteristics. The multi-resonances are obtained by applying a spiral facet technique on three different faces [left-front and bottom] of the intended rectangular DRA. A K10 material with a εr=10 and a dimension of 0.262λ0×0.22λ0×0.122λ0 has been preferred for fabricating the DRA. The proposed antenna operates at 5.2 GHz 5.8 GHz, 6.56 GHz and 6.88 GHz frquencies. The proposed technique helps to achieve circular polarization characteristics in the frequency range of (5.77-5.83 GHz). The maximum simulated gain achieved by the proposed antenna is 6.85 dB at WLAN 5.2 GHz frequency. A voltage doubler rectifier (VDR) configuration with an HSMS2860 diode has been investigated to integrate it with an antenna for RF energy harvesting purposes. The designed rectifier offers a maximum PCE and output voltages of 62% and 2.5V respectively. A good contract between measurement and simulated results is observed.

    In this paper, a quad-band dielectric resonator antenna (DRA) with dual-polarization characteristics for RFEH applications is stated. A spiral facet approach has been investigated and it is employed on four faces of the proposed DRA for obtaining multi-band characteristics. The antenna with four spiral facets on the left-bottom-top and rear surfaces offers better results over all other multi-facet combinations, and that design is considered the optimized one. A rectangularly shaped dielectric resonator ($13 \\times 11 \\times 6.3 \\mathrm{~mm} 3$) has been chosen for designing a DRA on a low-cost FR4 substrate ($66 \\times 68 \\times 1.6$ mm 3). The proposed antenna covers $5.0 \\mathrm{GHz}, 5.5 \\mathrm{GHz}, 5.8 \\mathrm{GHz}$, and 6.2 GHz bands. The proposed spiral facet technique offers an additional feature of providing Omni-directional characteristics.

    The most widely used approach for replacing traditional batteries and extending battery life is radio frequency energy harvesting (RFEH). However, the power density in the immediate environment is low thus the antenna with multiband features is essential to gather a huge amount of RF power from the low-density atmosphere. This paper presented a multiband dual-polarized dielectric resonator antenna for smart city applications using RFEH technology. The proposed DR antenna covers the frequency bands of WLAN 5.2 GHz, Wi-Fi 5.8 GHz, and future 6 GHz Wi-Fi bands of 6.2 GHz and 6.6 GHz. A rectangular dielectric resonator (DR) is fabricated using a K10 material and it is designed on a low-cost epoxy FR4 substrate (having εr=4.4). A coaxial probe feeding approach is used for excitation purposes. The substrate and DR material dimensions are 66 mm×68.2 mm×1.6 mm and 13.6 mm×11.4 mm×6.35 mm respectively. A spiral metallic coil is stuck on two faces (front and bottom) of a DR material to operate the antenna in the desired band of frequencies. The proposed technique is used to bring down the axial ratio (AR) value below 3dB level in two resonant bands. The maximum gain of 6.72 dB is observed experimentally at 5.2 GHz frequency.

    High transportation cost is a major feature of fresh agricultural products distribution, how to effectively optimize the path, and then reduce transportation cost is the key method to promote the development of fresh logistics. In contrast to the good development prospects of the cold chain logistics market of fresh agricultural products, the development of India's cold chain logistics industry has entered a bottleneck period. According to the characteristics of fresh agricultural products with short preservation period, the mathematical model of location problem of multiple distribution centers with time constraint was established in order to save various operating costs and minimize investment costs. Traffic flow prediction is the basis of traffic control and guidance. The traditional traffic flow prediction technology has been unable to meet the actual demand, and some prediction methods with higher accuracy, especially intelligent calculation methods, keep emerging. Through the optimization of the whole system, to achieve the standardization of the whole system, standardized development, to improve the circulation quality and efficiency of fresh agricultural products, promote the rapid and healthy development of Modern agriculture in India, is of great significance. The key of cooperative distribution is to distribute the profit reasonably among distribution centers. Therefore, the topic of this paper has important practical significance in solving practical problems.
