“…These novel concepts can be realized in EBGs with cavities or defects [2-5, 18, 19], which can function as resonators, waveguides and even horn antennas. Point defects in EBGs were applied to antennas in order to achieve larger directivities and higher efficiencies [20][21][22]. These compact defect-based antennas however resulted to be limited in terms of their operating bandwidth.…”

Abstract-This paper presents a novel pyramidal (EH) horn antenna based on Electromagnetic Band Gap structures (EBGs). The reported pyramidal woodpile-based horn antenna possesses a symmetrical radiation pattern and a wide operating frequency range. Such antennas can substitute metallic horns in certain circumstances, which is especially valuable for millimetre and THz devices. The principle of creating EH-horn antennas in the woodpile structure is explained in detail. In particular, this paper presents the design of a symmetrical woodpile EH-horn antenna operating at frequencies around 110 GHz. The reported antenna exhibits a wide operating bandwidth (more than 10%), while possessing high directivity and radiation efficiency equal to 16.35 dBi and −0.55 dB (88%) respectively.

“…To overcome those problems, an antenna covered with a photonic bandgap (PBG) resonator superstrate, which requires about halfwavelength separation between the antenna and the superstrate, was proposed and it showed a high-gain and high-directivity with only a single feeder [1]. Later, the PBG-type superstrate was substituted with a frequency selective surface (FSS) that was able to control a reflection phase of the superstrate resulting in a resonance length reduction between the superstrate and a ground plane [2,3].…”

Abstract-A new approach to analyze the behavior of a FabryPérot cavity type high-gain antenna covered with a frequency selective surface (FSS) superstrate is presented. Using an image theory and effective constitutive parameter retrieval, properties of impedance and a refractive index of the entire cavity structure are investigated. Through the analysis, we show that our antenna inherently operates in the medium whose maximum magnitude of the refractive index is lower than '0.5'.In consequence, we demonstrate that the high-gain feature of the Fabry-Pérot cavity antenna is not only due to satisfy a conventional cavity resonance condition, but also for a wave collimation effect of a metamaterial with the effectively low index of refraction. To show the collimation effect of the cavity, phase properties of a radiating wave with and without the FSS superstrate are examined. Moreover, the effect of the real and imaginary parts of the refractive index on behaviors of the antenna is also investigated by analyzing the derivative of a realized gain of the antenna within an impedance matched frequency band.

“…In [3], a study on the input impedance of the antenna has been presented. In [4,5], an antenna based on a Electromagnetic Band Gap (EBG) material with a defect has been proposed. The antenna consists of a Fabry-Perot cavity between a patch antenna and the EBG material.…”
