Millimetre‐wave (MmW) frequencies offer large bandwidth with which gigabit data rates can be easily achieved with simple radio architectures. At MmW frequencies, the short wavelength enables integration of the antenna on the same chip as the microwave monolithic integrated circuits. This research work emphasises on the design and development of antipodal linear tapered slot antenna (ALTSA) using substrate integrated waveguide (SIW) technique and its radio link characteristics at 60 GHz for wireless local area network and wireless personal area network applications. SIW feeding technique is used to eliminate the unwanted radiations from feed. The proposed antenna is designed and simulated using three‐dimensional (3D) electromagnetic tools. Radio propagation is profoundly site specific and depends on frequency of operation, interference from surroundings and other dynamic factors. To predict signal strength, delay and achievable data rates, it is important to characterise the radio channel. The radio link study is carried out using ALTSA with radio frequency measurement equipment to measure and characterise propagation channels in narrow hallway environment at 60 GHz.
Abstract-New generation wireless communications are expected to provide new services over the existing variety of wireless applications in the coming years. In this perspective, advances in utilization of computational electromagnetics (EM) and millimeter-waves (mmW) frequency bands make them as candidates for ultra-high-resolution and ultra-high-speed wireless communications. With the deployment of mmW wireless technologies, brinks of potential mmW induced biological and health effects should be evaluated carefully. The EM exposure is usually measured in terms of absorbed power from any user operating wireless devices. The exposure varies with the part of the body and location of the source that is exposed to the radio frequency waves. The purpose of this study is to observe EM exposure in terms of Specific Absorption Rate (SAR) and temperature elevations at mmWs from the designed Antipodal Linear Tapered Slot Antenna (ALTSA) at 60 GHz on different body parts utilizing EM computations and experiments with Infrared Thermal Camera.
A new design of a microstrip patch antenna with Twin Eleven shaped slot is presented that achieves a minimum impedance bandwidth of 37.931%. The Twin Eleven shaped slot increases the bandwidth and reduces the complication of design to a very high extent while compared to other slot geometries due to the similarity in the shape of slots that are made on the patch. The proposed antenna is designed for the 5 GHz ISM band and is designed and simulated by the electromagnetic simulation software HFSS. The VSWR curve and the radiation patterns are also demonstrated in this paper in which the importance is given to the antenna bandwidth.
