“…The distance between the via (S) is affected on the radiation losses will create because of the leakage field in SIW structure and S≤2d and d≤λg/5 are given ideal situation where the d is the diameter of the via. The guided wavelength for the dominant mode in SIW is obtained by Equation 2 [22]:…”

Recently, Substrate Integrated Waveguide (SIW) techniques have been noticed for millimeter wave devices in microwave applications. In this paper, we are developing a wide band directional 3 dB coupler with a phase of 90̊ phase delay in the range of 30-40 GHz based on periodic vias and multi hole structure. For achieving this wide bandwidth multi-section coupler is designed based on the theoretical modeling and the simulation result is compared with HFSS and CST with two different numerical methods show good performance with low insertion and return loss, broad operational bandwidth and high isolation. A fractional bandwidth is about 28.5 %.

In a hospital environment, continuous respiratory monitoring is important. It could reduce mortality incidents such as in central sleep apnea. Remote monitoring can be achieved using electromagnetic (EM) waves. Experimental EM systems use horn and patch antennas which do not offer low-profile or wide bandwidth features. This thesis proposes a substrateintegrated waveguide based antenna in respiratory monitoring.A leaky-wave array antenna is designed and fabricated. It operates between 8-9 GHz.The antenna size is 300 mm × 55 mm × 0.78 mm. It offers inexpensive beam-scanning ability to scan the bed. The antenna's beam width sufficiently covers a typical hospital bed.The fabricated antenna has measured return loss higher than 10 dB and radiates more than 90% of power in frequency range of interest. Measured main beam scans in E-plane (27• → 57 • ) with frequency. Measured peak gain is higher than 10 dBi.

“…In order to include the SIW vias in the design, the physical parameters of the SIW are valued as follows: the effective width w siw is calculated from a good estimation of the w rec / w siw relation defined in [14]. The values of the d diameter of the vias and the s distance between two consecutive vias are calculated from (9) and (10) [15], [16]:…”

A space leaky wave excited on composite rightleft handed substrate integrated waveguide and radiating in a wide frequency band is presented in this paper. The proposed two line array is a good candidate for smart systems of monitoring and tracking applications. The system is composed of two different lines that are placed in parallel on the same substrate. Simulation results show that the first line leaks energy in the band from 6.9 to 11 GHz with a 7.8 GHz broadside radiation frequency and the second line leaks in the band from 8.9 to 13.8 GHz; the related broadside radiation frequency is 10.2 GHz. Complex single/dual scanned beams are obtained in a wide range of angles from-72° to +73°. The simulations were carried out in the CST Microwave Studio and the obtained measurement results match well with the theoretical analysis described in this paper.
