Single-layer waveguide slot array antenna with diaphragms
A single-layer waveguide slot array antenna of low cost and high performance for a millimetre-wave wireless communication system at 38 GHz frequency band is presented. The waveguide slots and diaphragms are located together on the cover plate of the antenna, which makes the antenna cost effective and highly efficient. Measurements show a cross-polarisation level below 26 dB and an efficiency le...
متن کاملCorrugated Substrate Integrated Waveg- Uide (siw) Antipodal Linearly Tapered Slot Antenna Array Fed by Quasi-triangular Power Divider
In this paper, a new configuration of Tapered Slot Antenna (TSA) with improved radiation pattern is proposed and studied. This antenna is designed in the form of a substrate integrated waveguide (SIW) array with respect to side lobe level constraints. For side lobe reduction, a simple quasi-triangular distribution is proposed and is accomplished uniquely by means of 3 dB power dividers. A 12-wa...
متن کاملA high gain strategy with positive-feedback gain enhancement technique
Several new CMOS very high DC-gain amplifiers that use internal positive-feedback techniques are presented. These amplifiers have a controllable gain and don't require perfect matching of transistors to achieve the high DC gain. An implementation of a sample and hold circuit constructed using one of the proposed amplifiers is described. Sin~ulation results predict a DC gain larger than lOOdB is...
متن کاملSiw 2d Planar Array with Four Cross Slots Radiator and Tuning Vias
A Substrate Integrated Waveguide (SIW) planar array is presented using a right handed circularly polarized (RHCP) element with four crossed tilted radiating slots. In addition, a pair of metallic tuning vias is included to really improve the reflection of longest slots. A corporate feeding network over SIW has been designed for distributing the input signal to 128 radiating elements, divided in...
متن کاملW-Band SIW Power Combiner/Divider Based on the Antipodal Fin-Line SIW-RW Transition and Longitudinal-Slot Coupling Techniques
In this paper, a novel W-band substrate integrated waveguide (SIW) power combiner/divider is analyzed theoretically and demonstrated experimentally/numerically, based on the antipodal fin-line SIW-rectangular waveguide (SIW-RW) transition and longitudinal slot coupling techniques. This antipodal fin-line SIW-RW transition can work at the frequency band of 86.4GHz– 106.1GHz with return loss larg...
