“…Various ways have been implemented to enhance output power and reduce phase-noise of microwave oscillators. In recent years, substrate integrated waveguide (SIW) has not only a flat structure and easy integration compared with microstrip resonator, but also the traditional metal waveguide resonator's excellent advantages, such as low insertion loss, high Q-factor, high performance and high power capacity [1]. Thus, using a high Qfactor resonator such as SIW resonator as a frequency selective element is one of the most effective methods to realize low phase noise.…”

Abstract-A low phase noise reflection oscillator using a hexagonal substrate integrated waveguide (SIW) resonator is proposed in this paper. The hexagonal SIW resonator, which can combine flexibility of a rectangular cavity and performance of a circular cavity, is convenient for oscillator design. Since any of the six sides of a hexagonal resonator can be utilized for coupling, the oscillator configuration is flexible and adaptable. A simplified generalised phase noise condition and its optimization approach are proposed for the low-phase noise oscillator design. Furthermore, a 10.4 GHz oscillator prototype was designed, fabricated and measured to validate the proposed optimization approach. The measured results show that this oscillator provides 11.3 dBm output power and possesses low phase noise of −127.2 dBc/Hz at 1 MHz offset from 10.37 GHz carrier frequency, which is suitable for low-cost application in microwave and millimeter-wave band.

“…SIW permits to comprehend traditional rectangular waveguide components in the planar form. It is compatible with planar processing techniques like low-temperature cofired ceramic (LTCC) or standard printed circuit board (PCB) technology [6,8]. High-density integration of components is possible in Substrate Integrated Waveguide.…”

In this paper a laminated waveguide fed DR Antenna is investigated. It can use for moderate power military applications. Cylindrical DRA is excited by two closely spaced asymmetric longitudinal slots on the broad wall of the laminated cavity are responsible for producing three different frequency bands. Parametric study of slots has been done with the help of commercial software ANSOFT HFSS. All the bands have sharp rejection. The final model of the antenna is simulated, fabricated and experimentally measured. Measured results are in quite accordant with design results. SIW feeding structures have small losses, moderate power handling capacity, low costs, compact sizes and can be seamlessly integrated with planar circuits. At all the bands 9.76 GHz, 10.53 GHz and 11.8 GHz resonant frequency, the antenna shows 56 MHz, 160 MHz, and 250 MHz impedance bandwidth (for VSWR<2) with 6 dB,6.2 dB and 6.8 dB gain respectively. Simulated and measured results reveal outstanding performance with a cross-polar level of 29 dB lower than that of the co-polar level at 9.76 GHz, the cross-polar level of 32 dB lower than that of the co-polar level at 10.53, GHz, and similarly cross-polar level of 30 dB lower than that of the co-polar level at 11.8 GHz.

“…Accordingly, they allow burst data measurement and transmission, resulting in low duty cycle operation, yielding a low average power consumption. Antenna topologies based on substrate-integrated-waveguide (SIW) technology [11] [12] show high potential for integration into everyday objects and garments. Their planar structure and low profile allow unobtrusive embedding in any surface, by reusing the dielectric material of the object itself, which is cost and area effective.…”

A novel antenna-harvester co-design paradigm is presented for wireless nodes operating in an Internet of Things context. The strategy leads to compact and highly-integrated units, which are able to set up a reliable and energy-efficient wireless communication link, and to simultaneously harvest energy from up to three different sources, including thermal body energy, solar and artificial light. The core of the unit consists of a substrate-integrated-waveguide (SIW) antenna. Its surface serves as a platform for the flexible energy harvesting hardware, which also comprises the power management system. To demonstrate the approach, two different SIW cavity-backed slot antennas and a novel compact dual linearly polarized SIW antenna are presented. These topologies facilitate the integration of additional hardware without degrading performance. In the meantime, they enable comfortable integration into garments or unobtrusive embedding into floors or walls. Measurements on prototypes validate the integration procedure by verifying that the integrated hardware has a negligible influence on the performance of all discussed SIW antennas. Finally, measurements in four well-chosen indoor scenarios demonstrate that a hybrid energy-harvesting approach is necessary to obtain a more continuous flow and a higher amount of scavenged energy, leading to a higher system autonomy and/or reduced battery size.
