A novel structure of filtering antennas, termed as "transversal filtering antenna" (TFA), is introduced in this paper. Different from traditional filtering antennas which employ the ladder filtering structure, TFA employs a transversal coupling topology. Compared to traditional filtering antennas in which only the final stage of the filter antenna is radiating, one important advantage of TFA is that all the resonators in TFA will be radiating simultaneously. By controlling the excitation and radiation behaviors for each radiator, filtering response can be achieved for both S parameters and antenna gain. Flexible control of bandwidth and sharp roll-off of antenna gain can be achieved by using TFA. These novel characteristics bring some very promising possibilities for filtering array antennas designs. To demonstrate the validity of this novel topology, several design examples are presented. One prototype is designed, fabricated, and measured, and the measurement results agree well with the simulations.

Energy harvesting is a potential source of power for integrating compact low-power and self-sustainable wireless devices in ambient backscatter communication systems and IoT networks. In this paper, an electrically small circularly polarised (CP) slot antenna for harvesting is proposed. The measured CP bandwidth for axial ratio values less than 3 dB is 990 MHz (1.7 GHz to 2.69 GHz), while the measured impedance bandwidth is 1,930 MHz (1.45 GHz to 3.38 GHz). The proposed structure can harvest energy from common radio frequency signal emitters operating in GSM 1800/1900, 3G/LTE 2100, 3G/LTE 2300, 4G/LTE 2500, and 2.4GHz Wi-Fi bands, which makes it an attractive design within energy harvesting technology.

In the context of retrofitting a 3.8m C&Ku band parabolic dish antenna for the reception of FMCW signals at 5.84GHz in a bistatic radar configuration, this paper presents the design and selection of a suitable feedhorn. First, two feedhorn designs are proposed and the most suitable one is selected based on performance evaluation through simulations. Next, the selected feedhorn is manufactured and its performance is validated through radiation measurements in an anechoic chamber in terms of gain, beamwidth, and F/B ratio. Finally, the behavior of the antenna system comprising the parabolic reflector and the proposed feedhorn is illustrated by means of simulation.

In this article we compare two solutions to improve the radiation pattern of a slotted Substrate Integrated Waveguide (SIW) antenna: use of an E-plane array and covering it with a metasurface (MTS). To this aim, we compare the changes in performance, radiation pattern and aperture efficiency. We will see the advantages that the metasurface has over the typical array.

A microwave holographic-inspired metasurface antenna is proposed in this paper, which has the ability to create multibeam radiation patterns with independent beam steering. The design process follows the guidelines of holographic theory. The metasurface impedance modulation is generated by the superposition of each individual beam surface impedance modulation. The unit cell of the proposed antenna is tuned with a low-loss varactor diode. Simulated results for the novel multibeam antenna demonstrate an independent beam steering of each beam at around 7.4 GHz.

A novel miniaturized printed antenna placed on the side edge is investigated for fifth-generation wireless applications. The proposed two-element antenna is configured for multiple-input – multiple-output (MIMO) to cover the frequency band (3.625 – 3.77) GHz, with a resonant frequency at 3.7 GHz. Various locations for the indicated two-element antennas are examined in terms of scattering parameter S11, mutual coupling |S21|, radiation pattern, and gain. The MIMO antenna achieves a very low envelope correlation coefficient (ECC). The proposed antenna achieves a maximum gain of 3.38 dB with isolation better than 25 dB in the operating frequency range.

This paper presents an 868 MHz ultra-high frequency (UHF) bandage-type antenna for wireless body sensor network applications. The proposed antenna has a modified planar rectangular patch antenna topology and is realized using aluminum metalization and a flexible polydimethylsiloxane (PDMS) substrate. The performance characteristics of the antenna have been investigated through electromagnetic simulations and measurements on a human body phantom arm. The proposed antenna achieves a bandwidth of 11 MHz which is 57 % wider than the required bandwidth for the European LoRaWAN 868 MHz band operation. When compared to bandage-type Sub-GHz antennas reported in the literature, the proposed antenna exhibits desired gain and efficiency performance. Furthermore, the developed antenna demonstrates a low 10-g averaged SAR figure of 0.82 W/kg when 25 mW input power is supplied. The achieved impedance and radiation characteristics make the proposed antenna suitable for a wide range of body-worn wireless health monitoring applications.

This paper presents the development of circularly-polarized ring-shaped array antenna which is intended to work at the center frequency of 1.275 GHz for L-band radar application. The proposed array antenna which consists of 4×5 ring-shaped elements is differentially fed at the opposite side using proximity-coupling feeding in order to generate different phases among radiating elements producing circular polarization. The measured reflection coefficient (S11) has good agreement to the simulated result with –10 dB impedance bandwidth of 76 MHz in the frequency range of 1.217–1.293 GHz for both, while the measured 3 dB axial ratio bandwidth is 30 MHz. In addition, the dimension of array antenna fabricated on two layers of FR4 epoxy dielectric substrate is 0.847 λ0×0.805 λ0.

In this paper, we propose four elements proximity-coupled multi-input-multi-output (MIMO) micro-strip patch antenna working from 27 to 29.16 GHz for 28 GHz mm-wave 5G applications. We begin with the development of a single element, which is made of two layers of Rogers RT5880 substrate with a relative permittivity of 2.2. A parametric analysis, based on finite difference time domain analysis (FDTD), is conducted to boost the structure’s performance. A quad-element arrangement is examined for the MIMO antenna. Additionally, the isolation is improved by using the spatial diversity approach, which achieves better than 24 dB of isolation over the targeted frequency spectrum. The envelope correlation coefficient (ECC) and the diversity gain (DG) are determined to be within acceptable bounds. The results indicate that the design is an interesting candidate for upcoming mm-wave 5G MIMO applications.

The use of a switchable circle loaded dumbbell defective ground structure (DGS) for wideband isolation of a millimeter-wave (mm-wave) single pole double throw (SPDT) discrete radio frequency (RF) switch in a 5G application is discussed in this research. To examine the performance of the SPDT switch with switchable DGS, it was built and then simulated in CST Microwave Studio software. The performance of the switchable DGS was validated by fabricating and measuring the switchable DGS. As a result of the simulation and measurement, the switchable DGS has a wideband bandstop response with good attenuation (> 10 dB) and thus assisted the SPDT switch in producing usable wideband isolation with fractional bandwidth (FBW) of 15.49% at isolation levels greater than 30 dB for the 26 GHz band mm-wave. Furthermore, the SPDT switch's transmit mode exhibited low insertion loss (< 1 dB) and high return loss (> 10 dB), indicating a good allpass response.
