A microfluidically reconfigurable frequency tunable mm-wave patch antenna is presented. Different than the previously reported work on microfluidically reconfigurable RF devices, the actuation of the multiple metallized plates reconfiguring the antenna is carried out by using a piezoelectric disk within a multilayered fluid reservoir stack. The antenna operates with 7% and 9%|S11| <-10 dB impedance matching bandwidth in its 28 GHz and 38 GHz states respectively. Additionally, it exhibits a simulated realized gain of 5.66 dBi and 4.9 dBi at 28 GHz and 38 GHz, respectively.

This paper demonstrates the concept and feasibility of using higher-order space harmonics (HSH) in the development of one-dimensional periodic leaky wave antennas (1D-periodic LWAs). A methodology for analyzing the behavior of the propagation constant ($beta_{mathrm{n}}$) of HSH is presented by introducing two new concepts, namely safe zone area (SZA) and boundary region. They allow us to identify the number of beams and frequency bands to achieve multi-band and multi-beam antennas (MBMBAs). The proposed analysis methodology is experimentally validated by prototyping a dual-band multi-beam LWA (MBMB-L WA) based on substrate integrated waveguide (SIW) technology where the $mathrm{n} epsilon[-1, -2]$ space harmonics are utilized for achieving such a design. The measurement and simulation results show a good agreement with the theory and analysis of HSH.

A novel wideband circularly polarized (CP) leaky-wave antenna (LWA) is developed in this paper. The proposed antenna consists of sixteen unit-cells, each of which combines a slot (magnetic dipole) and an electric dipole. A conventional slotted substrate integrated waveguide (SIW) LWA in the lower layer and the electric dipoles are etched on the upper layer. Two kinds of dipoles are placed in parallel to produce two orthogonal polarization components which results in the required CP operation. The CP LWA is designed and fabricated to operate at the 26 GHz Ka band. Measured results show that the antenna has a peak gain of 17.1 dBic with circular polarization throughout the frequency range from 24–28 GHz.

Radio frequency identification (RFID) readers record enormous amounts of data from passive tags located throughout the environment. Due to the large data sets RFID readers collect, machine learning approaches can be used to train robust models. This paper develops an RFID based tire classifier using support vector machines (SVMs). The algorithm correctly identifies all tires in a lab environment and simulations show how the algorithm performs with increased path attenuation.

In this paper, a circularly polarized, wideband, high gain antenna supported by an origami structure is presented. This antenna consists of a Yagi-Uda inspired end-fire array of crossed bowties. An ideal phase shift was implemented to obtain a circular polarization. Each element of the proposed array is printed on FR-4 substrate and inserted in different sections of a Kresling origami pattern. The proposed antenna exhibits wideband operation from 200 to 350 MHz (54.5%), where S11≤ −10 dB and axial ratio≤ 3 dB are maintained. High gain (7 to 9 dBc) is achieved by such an array of parasitic elements. The origami structure allows a compact stowage (i.e, packaging efficiency of ~95%) as well as fast and easy deployment. The antenna design procedure and analysis are also discussed in this paper.

An artificial intelligence-assisted reflector antenna deformation localization method based on the focal-field distribution (FFD) feature is presented. Exploring the characteristics of FFD, a capsule network (CapsNet)-based estimation method is used to locate the deformation. The Five-hundred-meter Aperture Spherical radio Telescope (FAST) model is used to verify the effectiveness of the proposed method, and the experimental results confirm that our method can accurately locate the deformation of the reflector antenna.

In this paper, a new method to broaden the bandwidth of dual-polarized cross-dipole antennas is presented. By connecting a thin loop to a traditional cross-dipole, additional resonant points are introduced and the bandwidth is broadened. This method does not increase the physical dimension of the antenna and has little influence on radiation performances. A loop-connected cross-dipole antenna is presented to verify the method. The bandwidth it achieves is 66.7% from 1.65 GHz to 3.30 GHz with a very compact radiator size. The antenna also has a high port isolation level and stable radiation performances, making it highly suitable for the base station application.

In this paper, a novel planar array antenna with filtering functionality is presented. The main idea is to integrate both the antenna and filter with a combined treatment. The coupled radiating resonators are effectively adopted to obtain a fourth degree steep roll-off filtering antenna (filtenna). The proposed antenna is a 2*2 cavity-backed slot array antenna built by substrate integrated waveguide (SIW) technology. The proposed slot array filtenna take the advantages of total size reduction, efficient utilization of RF power and spectrum as well as enhanced signal-to-noise ratio (SNR). The design methodology is verified by achieving return loss and realized gain better than −15 dB and 9 dBi, respectively, which exhibits unique capability of the proposed method.
