Wideband and high‐gain EBG resonator antenna based on dual layer PRS

Abstract

A wideband and high‐gain electromagnetic band‐gap resonator antenna for X‐band operation is presented in this paper. A dual‐layer partially reflective surface with a wide frequency band from 8.3 to 11 GHz is proposed to enhance the 3‐dB gain bandwidth of a simple planar antenna. The measured results indicate that the proposed antenna possesses a relative 3‐dB gain bandwidth of about 33.33%, from 7.95 to 11.13 GHz, with a maximum gain of 13.57 dBi. Moreover, the measured impedance bandwidth is about 35.53%, from 7.8 to 11.17 GHz, which fairly covers the 3‐dB gain bandwidth. Hence, the proposed structure surpasses conventional techniques for widening the 3‐dB gain bandwidth. © 2016 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:98–101, 2017

A Novel Wideband Partially Reflective Surface for Antenna Gain Enhancement

“…The reflection phase augments from 125.56 to 164.15 over a broadband extending from 7.76 to 11.16 GHz with reasonable reflection magnitude values predicting the enhancement of the gain of printed antennas over the whole frequency range. Noting that this achieved frequency range of 3.4 GHz, in which the reflection phase increases, is larger than the bands attained by the PRSs presented in [1] and in [3,4].…”

“…Here, the role of the PRS is to create a partial blocking for the radiated waves emitted by the feeding antenna (FA). Accordingly, the radiated waves incur several reflections before their escape throughout the PRS as extremely directive emission [3][4][5][6][7][8][9][10][11][12]. Fabry-Perot cavity that was firstly introduced in 1956 by Von Trentini is well known for its aptitude to enhance the gain of printed antennas by the implementation of mightily reflective surfaces at a delicate altitude in order to create constructive wave interference between the direct rays radiated by the FA and the rays reflected by the PRS [13][14][15][16][17][18][19].…”

Development of Multilayer Partially Reflective Surfaces for Highly Directive Cavity Antennas: A Study

“…Multilayer PRS broadband and high-gain antennas are analysed by Konstantinidis et al and Mohammed Aymen et al [13][14][15]. High-gain single-layer and multilayer antennas with di erent feed radiators and polarizations are analysed [8,[16][17][18][19][20][21][22][23][24][25][26][27][28][29]. e FPC antennas nd wide applications in modern wireless communication, in radars (RCS reduction), and in networking sectors [30][31][32].…”

Coupling Substrate-Integrated Waveguides to Increase the Gain Bandwidth of Leaky-Wave Antennas

“…This coupled SIW LWA topology is inspired by a similar multi-layer arrangement used for Fabry-Pérot cavity antennas (FPA) [19]- [25]. The addition of extra coupled FP cavities has demonstrated increased pattern bandwidth for high-gain broadside radiation compared to the original single-cavity FPA.…”
