A dielectric waveguide antenna for X-band is designed. A printed dipole fed by a coplanar strip excites the Ex11 mode inside the dielectric waveguide. The waveguide mode in its turn excites a properly dimensioned patch, which generates the radiation pattern. Simulations are conducted from the stand-alone waveguide up to the complete structure to reveal the coupling and scattering effects between the...
In this paper a conformal cylindrical microstrip antenna (CMA) with an omnidirectional radiation is proposed. The antenna consists of three main components: a probe-fed main patch and two parasitic patches, placed conformally on a cylindrical structure. This cylindrical structure is sized to be about the size of a typical human waist, and was designed in the form of a belt for horizontally-polarized...
Multi-objective synthesis for microwave components (e.g. integrated transformer, antenna) is in high demand. Since the embedded electromagnetic (EM) simulations make these tasks very computationally expensive when using traditional multi-objective synthesis methods, efficiency improvement is very important. However, this research is almost blank. In this paper, a new method, called Gaussian Process...
Solving Integral Equations with the Method of Moments has been a cornerstone in the field of computational electromagnetics for components and antennas in the microwave frequency range. In this invited paper, the applicability, advantages and disadvantages of this method are discussed in view of applying it at much higher frequencies, namely in the IR and optical frequency range. This invited presentation...
This paper gives an overview of the antenna software benchmarking activity that took place within the Software Group of the EurAAP association in 2009. A particular focus is brought to one of the proposed test case that consists of a non conventional horn antenna.
In this paper, a new design for a Log-periodic antenna with omni-directional radiation pattern in the horizontal plane and broad-band characteristics is investigated. This antenna covers the 500–3000 MHz band with VSWR < 3:1 and the gain better than 0 dBi with maximum deviation ±1.5 dB in the entire frequency bandwidth.
