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.

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.

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.

Liver cancer is one of the most deadly diseases worldwide with an increasing yearly fatality rate. Thermal ablation treatments are considered to be an effective alternative to conventional surgery, but the lack of an effective imaging modality to monitor the treatment prevents from a full exploitation of their therapeutic potential. As such, there is an increasing interest in developing alternative imaging modalities. In this framework, due to the fact that thermally treated tissue exhibits different dielectric properties as compared to untreated tissue, microwave imaging is a potential candidate, offering the possibility of performing the treatment monitoring task in a truly non-invasive way and by means of a portable and low cost apparatus. In this communication the prototype of a microwave imaging system to monitor thermal ablation of liver is presented together with its initial experimental validation. The observed results, although still preliminary, confirm the anticipated treatment monitoring capabilities of microwave imaging.

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, a planar rhombus-shaped microstrip patch antenna is proposed at 60 GHz ISM band for multi-gigabit per second level industrial communication in viewpoint of Industry 4.0. The proposed has -10 dB impedance bandwidth of 2.82 GHz at 60 GHz. The single antenna element presents excellent return loss of -65 dB at 60 GHz, high radiation efficiency of above 92.5 % in the whole band, and peak realized gain of 5.25 dBi. The radiation pattern of the antenna is stable in the whole band. The simulated 8 elements based linear array provides gain of 17.5 dBi and half power beamwidth of 8o in azimuth. The proposed antenna can be reconfigured at different resonance frequencies by altering the radius of the rhombus-shaped patch. The proposed antenna finds its applications for indoor industrial and factory automation operations in the unlicensed 60 GHz ISM band (IEEE 802.15.3c, 802.11ad and 802.11ay), as well as 60 GHz indoor localization.
