“…TEM mode of wave propagation in SICL can simultaneously support the operating bands of upcoming 5G communication and also provide backward compatibility to 3G/4G. In [9] and [10], a coaxial to SICL transition has been reported. A novel rectangular waveguide to SICL transition is proposed in [11] to act as a four way power divider to feed a circularly polarized antenna array in E-band.…”

In this communication, the design and working principle of a wideband microstrip to substrate integrated coaxial line (SICL) planar transition for millimeter-wave applications is presented. In the proposed work, along with tapering of microstrip line, two triangular slots in the top ground plane are utilised to compensate for the discontinuity arising at the microstrip-SICL junction & minimize reflections over a wide bandwidth. To confirm the theoretical claims, the proposed microstrip to SICL transition is fabricated using standard multilayer PCB process. The measured results of the prototype indicate return loss better than 14 dB with a maximum insertion loss of 1.78 dB for DC to 40 GHz band (19 dB bandwidth up to 20 GHz with insertion loss less than 0.71 dB). The modeling of proposed transition is presented & versatility of the design is illustrated for different dielectric constant & thickness. Effortless integration of SICL with the widely used microstrip transmission line simplifies the feeding process of SICL based broadband antennas & microwave circuits. INDEX TERMS Millimeter-wave, planar, substrate integrated coaxial line (SICL), wideband transition.

In this paper, a horn-shaped strip antenna exponentially tapered carved on a multilayer dielectric substrate for an indoor body position tracking system is proposed. The performance of the proposed antenna was verified by testing it as a tracking state of an indoor resting body position. Among different feeding techniques, the uniplanar T-junction power divider approach is used. The performance verification of the proposed antenna is explained through its compact size and 3D shape, along with a performance comparison of the return loss radiation pattern and the realized gain. The suggested antenna has an 88.88% fractional bandwidth and a return loss between 6 and 15.6 GHz, with a maximum gain of 9.46 dBi in the 9.5 GHz region. Within the intended band, the radiation pattern had an excellent directivity characteristics. The proposed antenna was connected to an NVA-R661 module of Xethru Inc. for sleeping body position tracking. The performance of the antenna is measured through microwave imagining of the state of the resting body in various sleeping positions on the bed using a Recurrent Neural Network (RNN). The predicted outcomes clearly define the antenna’s performance and could be used for sensing and prediction purposes.
