“…For wireless communication devices, a coplanar waveguide (CPW) and photovoltaic cells were integrated, boasting a transparency rating of 63.3%. Crafted from Plexiglas with a dielectric value of 4.4, the antenna operates from 2 to 32 GHz [6]. Another 1 × 4 Vivaldi antenna array spans a broad frequency range of 6.3 GHz (10.78-17.07 GHz) with an optimal gain of 13 dBi at 15 GHz [7].…”

In this paper, a miniaturized millimeter-wave (mm-wave) antipodal Vivaldi antenna (AVA) is proposed. The AVA antenna structure is modeled using MWSCST2022 optimization tools. The AVA exhibits good impedance matching, high gain, and a small optimum size of 5 × 2.5 × 1.5 mm 3 , fabricated on an FR-4 substrate. An array of square and circular director units is modeled and loaded at the front and back of the AVA antenna. The spacing between directors is studied and positioned at a tuned distance from the antenna for gain improvements and optimum radiation parameters. The AVA has an operating spectrum from 58 GHz up to 62 GHz. The finalized AVA, along with directors, obtained a high gain of 12.9 dBi with directors, while the AVA achieved 9.22 dBi without directors. The proposed antenna model is simulated and measured for short-range communications and imaging. The results of the modeling techniques and measurements agree well with each other.

“…The only issue with SWB antennae is their limited operating range, which is caused by low transmission power. Several SWB monopole antennae with different geometries have recently been reported by numerous researchers [9][10][11][12][13][14][15]. In [9], an antenna with SWB range was presented that consisted of a conventional circular-shaped patch, a tapered feed line, and a rectangular-shaped ground surface, with a frequency ratio of 16:1.…”

“…Two notch bands were also achieved by using circular rings loaded in the modified circular-shaped radiator. In [12], a coplanar waveguide (CPW)-fed semi-circular-shaped antenna was designed with transparent plexi-glass and a solar panel to power mobile devices. In [13], an offset-fed elliptical ring-shaped antenna for SWB applications was designed, with the antenna radiator fed through a tapered feed line to achieve impedance matching.…”

Design and Implementation of a Planar MIMO Antenna for Spectrum-Sensing Applications

Spectrum sensing is an important aspect in cognitive radio (CR) networks as it involves the identification of unused frequency spectra, which saves both bandwidth and energy. The design of a compact super-wideband (SWB) multi-input multi-output (MIMO)/diversity antenna with triple-band-notched features is presented for spectrum sensing in CR systems. The MIMO antenna comprises four identical semi-elliptical-shaped monopole resonators, which are orthogonally positioned and excited individually via tapered coplanar waveguide feed lines. Also, a mirror-slot analogous to the radiator is etched in the ground conductor of each antenna element to achieve SWB characteristics. In order to avoid interference with the SWB, the antenna radiator is loaded with a staircase-shaped slit and a pair of concentric slits, arranged like a complementary split-ring resonator. The antenna resonates from 1.2 to 43 GHz, exhibiting a bandwidth ratio of 36:1. In the MIMO antenna, the antenna elements are located orthogonally, and the isolation > 18 dB and envelope correlation coefficient < 0.01 are realized in the resonating band. The antenna offers a peak gain of 4 dBi, and a sharp reduction in gain at notch frequencies (3.5 GHz, 5.5 GHz, and 8.5 GHz) is achieved. The size of the MIMO antenna is 52 mm × 52 mm. The proposed compact-size antenna features a high bandwidth ratio and straightforward design procedure, and can be simply integrated into contemporary RF equipment. The presented SWB MIMO antenna outperforms SWB antenna designs reported in the open literature, which featured one or two notched bands, whereas it has three notched bands. Also, the three notches in the SWB are achieved without the use of any filters, which simplifies the antenna development process.

“…Recent years have seen the development of highly integrated multifunction devices as an effective means of achieving high-performance and low-cost solutions. Incorporating solar panels into electronic devices is a prime example of multifunctionality [1,2]. This approach is particularly crucial in space communications where sunlight energy harvesting is required [3,4].…”

In dual-band RF front-end systems, to transmit different frequency signals in different paths, each path requires the power to be divided along two transmission channels. In such systems, a circuit is created in which the input ports of power dividers with different frequency bands are connected to the output ports of a diplexing circuit in a cascade form. These circuits often contain different band filters in their schemes and have a complicated design. In this paper, an innovative technique for designing a diplexing power divider for Ku-band applications is presented. The proposed structure is designed on multilayer printed circuit boards (PCBs) and the utilization of a transition based on an extended SMA connector. The extended SMA connector provides two separate paths for the transmission of the RF signals. Hence, the proposed structure eliminates the need for intricate and bulky bandpass filters, allowing seamless integration with other planar devices and components within Ku-band satellite subsystems. In fact, the proposed architecture channelizes the divided output electromagnetic signals into two separate frequency spectrums. With the presented technique, two frequency ranges are envisaged, covering Ku-band applications at 13–15.8 GHz and 16.6–18.2 GHz. With the proposed structure, an insertion loss as low as 1.5 dB was achieved. A prototype of the proposed power-divider diplexing device was fabricated and measured. It exhibits a good performance in terms of return loss, isolation, and insertion losses.
