“…If the radome under test is a large structure that is made in several pieces, it is possible to complete panel testing on each unit to measure the RF performance of the radome [13]. However, for monolithic radomes, the interaction of the radome with the antenna is greater and panel testing will therefore be useful for understanding the RF performance of the radome material [14]. AC testing of the antenna and radome system should be carried out to characterise the radome.…”

A radome has to be carefully designed to ensure it has minimum impact on the performance of the antenna. Traditional approaches involve equation approximations, complex ray tracing, iterative manufacturing process and or electrically large and lengthy Electromagnetic (EM) simulations. The novel approach described in this paper involves a 2D Ray Tracing Method (2DTRM) simulation in MATLAB and an electrically small unit cell simulation in HFSS. This new approach gives an optimal thickness result that is only 0.004mm different to that of a full EM simulation. The radome is manufactured and Radio Frequency (RF) tested in an Anechoic Chamber (AC), the calculated thickness is shown to be the optimal thickness.

“…By definition, a radome is a structural enclosure that protects an antenna and is constructed of materials that minimally attenuate the electromagnetic signal transmitted and received by the antenna [ 27 , 28 ]. The materials used in the radome construction include fiber reinforced plastics (FRP), glass reinforced plastics (GRP), polypropylene (PP), acrylonitrile butadiene styrene (ABS), polystyrene unplasticized polyvinyl chloride (UPVC), and polycarbonate [ 29 , 30 ].…”

This research proposed a portable wideband horizontally-polarized directional antenna scheme with a radome for digital terrestrial television reception. The operating frequency band of the proposed antenna scheme is 470–890 MHz. The portable antenna scheme was an adaptation of the Yagi-Uda antenna, consisting of a folded bowtie radiator, a semicircular corrugated reflector, and a V-shaped director. Simulations were carried out, and an antenna prototype was fabricated. To validate, experiments were undertaken to assess the antenna performance, including the impedance bandwidth (|S11| ≤ −10 dB), gain, and unidirectionality. The measured impedance bandwidth was 75.93%, covering 424–943 MHz, with a measured antenna gain of 2.69–4.84 dBi. The radiation pattern was of unidirectionality for the entire operating frequency band. The measured xz- and yz-plane half-power beamwidths were 150°, 159°, 160° and 102°, 78°, 102° at 470, 680, and 890 MHz, with the corresponding cross-polarization below −20 dB and −40 dB. The radome had a negligible impact on the impedance bandwidth, gain, and radiation pattern. The power obtained for the outdoor test, at 514 MHz, was 38.4 dBµV (−70.4 dBm) with a carrier-to-noise ratio (C/N) of 11.6 dB. In addition, the power obtained for the indoor test was 26.6 dBµV (−82.2 dBm) with a C/N of 10.9 dB. The novelty of this research lies in the concurrent use of the Yagi-Uda and bowtie antenna technologies to improve the impedance bandwidth and directionality of the antenna for digital terrestrial television reception.

“…The power transmission efficiency of the graded panel sheet with the size of 100 × 100 mm is tested by free space transmission method in a dark microwave room, which is similar to the method in Refs. [28,29]. It consists of a network analyzer where the incident and transmission ports are connected to two horn antennas located on each side of the test panel.…”

Abstract-Silicon nitride (Si 3 N 4 ) ceramic is a promising ultra-high speed (> 5 mach) broadband (1-18 GHz) radome material because of its excellent high-temperature resistance, good mechanical and dielectric properties. Si 3 N 4 ceramics with A-sandwich wall structure are successfully applied to passive self-direction high transmission efficiency broadband radome (1-18 GHz). In the present study, a novel graded porous wall structure for broadband radome is promoted. The feasibility of using this structure is carried out by a computer aided design for the wall structure based on the microwave equivalent network method. By optimizing the layer number (n), structural coefficient (p), thickness (d) and dielectric constant (ε) of each layer, the power transmission efficiency at 1-18 GHz of graded porous Si 3 N 4 ceramic radome is calculated. Si 3 N 4 ceramics with graded porous structure are then prepared according to the design. The prepared sample exhibits a good graded porous structure with the porosity range from ∼ 2% to 63 %. The tested power transmission efficiency at 1-18 GHz for the obtained sample matches well with the calculation results, indicating that the graded porous structure is feasible for the broadband radome application.
