“…These involve use of metamaterial-based reflectors (Cui et al 2017;Li et al 2018), usage of cavity structures for gain enhancement (Saurav et al 2015b(Saurav et al , 2015a, introduction of multiple resonances to expand operating bandwidth (Saurav et al 2016;Wen et al 2018), and inclusion of magnetoelectric dipole structures to enhance pattern stability (Ye et al 2020;Shang et al 2023). Crossed dipoles are extensively used in wireless base stations, satellite communication (Ta & Park 2017;Park 2014), and more recently wireless power transfer research (Liao et al 2022). Ta et al (2015) provide a detailed review of diverse designs and alternative applications of crossed dipoles.…”

There exist inevitable deviations in the cosmic microwave background spectrum from that of a blackbody. The additive distortions from photons emitted over the epoch of recombination are one such deviation. We present a novel scalable broadband antenna design motivated by detecting these spectral distortions in the 2.5–4 GHz band. This antenna is capable of maintaining the spectral quality of the measured sky spectrum to 1 part in 103 over the full band and outperforms conventional broadband antennas by at least an order of magnitude. While this is not sufficient to make a direct detection of the cosmological recombination radiation, it meets the baseline design criteria for an experiment that can make an absolute measurement of the sky spectrum at the millikelvin level, thereby making it capable of improving foreground models to global signal detection experiments (including those from cosmic dawn and the epoch of reionization) and addressing the problem of the excess radio background at 3.3 GHz reported by the ARCADE2 experiment.

Design of a Dual-Polarization Dipole Antenna for a Cylindrical Phased Array in Ku-Band

This paper proposes a dual-polarization dipole antenna for a cylindrical phased array working in Ku-band. The dipole antenna is double-layer structured and is composed of two orthogonal butterfly shaped dipole radiators, two ground co-planar waveguide (GCPW) feeding structures and vias. Each dipole is in the shape of a butterfly. The dipole patch is grooved triangularly and one side of it is bent into an N shape, which effectively expands the working frequency band of the antenna. The double-layer structure improves the isolation between the antenna ports. The antenna works between 15 GHz to 16.2 GHz and the isolation between the antenna’s two feeding ports in this band is better than 20 dB. The proposed dipole antenna is applied in a 32-element cylinder array. The simulation and measured results show that the array can scan between −60° to +60° in the azimuth plane with a gain fluctuation less than 2.5 dB. Therefore, the proposed design is an attractive candidate for conformal devices at Ku-band frequencies, and it also has a great potential for application in larger antenna arrays.

“…To realize SWIPT operation, several techniques can be employed, such as power splitting [5]- [7], time splitting [5], dual polarization [8], [9], frequency splitting [10], and space splitting [11], [12]. The power-splitting technique divides the received signal into two power ratios, one for information decoding and and the other one for radio frequency (RF) power harvesting, as shown in Fig.…”

“…In contrast, the frequency splitting technique, Fig. 1(d) utilizes different frequency channels for the information and the power transfer [10], [14], [15] whereas, in dual-polarization [8], [9], [16] technique, Fig. 1(e), crosspolarized ports are employed at the same frequency of operation.…”

An integrated, miniature, dual-purpose circular patch antenna is proposed for Simultaneous Wireless Information and Power Transmission (SWIPT). The design proposes a proximity-coupled feed to the radiative circular patch for Wireless Information Transfer (WIT) in 5.7 GHz -6.0 GHz band and an integrated capacitive-coupled feeding network, with full-wave rectification (FWR) using regenerative opposite fringing fields from the radiating edges of the patch for energizing IoT sensors by means of wireless power transfer (WPT) at 5.2 GHz. For the realization, two co-polarized fringing field harvesters are capacitively coupled to the radiating edges of the patch to regenerate those opposite fringes whose currents are effectively matched to the FWR using a pair of Schottky diodes for direct current (DC) power generation. Since the gain and efficiency of the patch, in WIT mode, are favoured when using the FWR network, the effective regenerative fields, which are deemed attractive in modern wireless sensor network (WSN) applications for boosting the lifespan of sensor nodes.
