This paper describes the design and evaluation of a Substrate Integrated Waveguide (SIW) antenna operating at 2.4 GHz. This antenna was designed as a possible solution for the implementation of the vehicular networks (VANETs). The main advantages of the SIW antennas, such as their simplicity, small size and low cost, make this kind of antennas particularly suitable for using in wireless nodes where the size is a critical factor. For example, in Vehicular Networks (VANETs) which is one of the most promising wireless communication systems. We present in this paper the design of the SIW antenna using the software ANSYS HFSS as well as the results of the assessment of some parameters like the radiation pattern, operation frequency and bandwidth. Also, we present the simulation of a VANET that include the designed parameters of the SIW antenna in order to evaluate its integration into the vehicular nodes. This simulation was performed in the NS2 simulator and some network performance metrics, like packet delay and the packet loss rate, were evaluated. Other additional software, for example MOVE and SUMO, were also used to generate the routes and the movement of the vehicles

This paper introduces a microstrip square patch antenna with a novel low-cost and efficient feeding mechanism for millimetre-wave frequencies targeting at 28 GHz. The radiating patch is excited by the technique of empty substrate integrated waveguide, and two different slot configurations have been examined in this regard. It has been observed that the antenna gain profile and radiation efficiency is significantly improved in both configurations as compared to the microstrip square patch antenna provided with conventional feeding.
In this paper, a two-dimensional cylindrical Lens antenna based on the parallel plate technique is designed. It supports beam-steering capability of 58 degree at 28 GHz. The antenna is composed of low loss rectangular waveguide antennas, which are positioned around a homogeneous cylindrical Teflon lens in the air region of two conducting parallel plates. The Beam scanning can be achieved by switching between the antenna elements. The main advantages of our design include its relative simplicity, ease of fabrication, and high-power handling capability. Compared to previous works including a cur…
In this paper, a wideband high-gain 2 ? 2-element subarray is presented for 60 GHz band applications. The antenna is fed with waveguide-fed cavity backed configuration and designed entirely via simple rectangular apertures. To improve radiation pattern characteristics and reduce the antenna size, stepped-radiating apertures loaded with a solid dielectric material. A standard WR-15 rectangular waveguide is designed to excite the antenna at the input port over the operation frequency. The most significant advantage of using this design is its efficient radiation patterns, ability to decrease com…

Filtering modules are essential devices of modern microwave systems given their capability to improve the signal-to-noise ratio of the received signal or to eliminate the unwanted interferences. For discriminating between different components, a filter exhibits a frequency-selective response that, however, is not able to distinguish between different signals whose spectrum falls within the passband of the filter itself. In this regard, some electromagnetic structures exhibiting, at the same frequency, different responses depending on the waveform of the incoming waves have been recently propos…
