A Low-Profile Antenna Based on Single-Layer Metasurface for Ku-Band Applications

Abstract

Improvement in the antenna gain is usually achieved at the expense of bandwidth and vice versa. This is where the realization of this enhancement can be made through compromising the antenna profile. In this work, we propose a new design of incorporating periodic metasurface array to enhance the bandwidth and gain while keeping the antenna to a low-profile scheme. The proposed antenna was simulated and fabricated in order to validate the results in the operating frequency range from 10 MHz to 43.5 GHz. Computer simulation technology (CST) microwave studio software was used to design and simulate the proposed antenna, while LPKF prototyping PCB machine was utilized to fabricate the antenna. Results showed that the antenna generated a gain and bandwidth of 14.2 dB and 2.13 GHz, respectively. Following the good agreement between the numerical and measurement results, it is believed that the proposed antenna can be potentially attractive for the application of satellite communications in Ku-band electromagnetic wave.

A Symmetrical Terahertz Triple-Band Metamaterial Absorber Using a Four-Capacitance Loaded Complementary Circular Split Ring Resonator and an Ultra-Thin ZnSe Substrate

“…Metamaterials (MTMs) are artificial structures that exhibit exotic properties of negative permittivity, negative permeability, and a negative refractive index in the frequency range of interest [1]. Metamaterials can be used for various applications such as sensing [2,3], super lensing [4,5], cloaking [6,7], imaging [8], antennae [9], and wave absorption [10]. Studies on micro-and nano-sized designs in high frequency bands have been paired with technological developments; this is specifically important for the development of high chemical selectivity and the penetration of opaque materials.…”

Miniaturized Wideband Antenna Prototype Operating over the Ku-Band

“…A compact low-cost PRS having a non-uniform double-sided printed single-layer dielectric slab was proposed in [ 13 ]. Similarly, different shapes of unit cell patch designs were studied in [ 14 , 15 , 16 , 17 , 18 , 19 ], where the use of electrically thin substrates with the respective designed patches was shown. This further shows the design complexity with a complex geometry, which results in an increased fabrication cost.…”

Design and Modelling of Ladder-Shape Topology Generating Bandpass NGD Function

“…It is noteworthy to highlight that the NGD solution enables preservation of the signal quality without affecting the information speed. The NGD function was innovatively implemented within microwave circuits [15] as antenna [16,17] and sensor [18][19][20] performances by using negative refractive index resonant metamaterials, antenna beamformer [21,22], non-Foster network designing [23], and independent frequency NGD phase shifter [24]. Analytical modeling of transmission line (TL) and electrical interconnects were developed [25].…”
