“…In Ref. [8], coverage of 4G-LTE, WiMAX, WLAN, and S/C/X-bands was achieved by adding inverted-T-shaped stubs and E-shaped stubs to the ground of the etched rectangular slot. Moreover, rectangular slots were etched on the feeder to improve the impedance matching.…”

In this paper, a monopole UWB broadband antenna is designed, fabricated, and measured for wireless communication networks. The initial radiator model of the proposed antenna has a short-sleeve shape, and to expand the impedance bandwidth, the right and left angles are subtracted symmetrically from the lower half of the radiator. The impedance matching is improved by etching slots in the feed line and adding L-shaped patches symmetrically on both sides of the feed line. The results show that the proposed miniaturized antenna system can cover WiFi 7(2.4–2.484 GHz, 5.15–5.35 GHz, 5.725–5.825 GHz, 5.925–7.125 GHz), 4G LTE (2.3–2.39 GHz, 2.555–2.655 GHz), 5G (4.8–5.0 GHz), X-band (7–12.4 GHz), Ku-band (10.7–14.59 GHz), and C-band uplink bands (5.925–6.425 GHz). Moreover, the antenna is found to be omnidirectional at low frequencies, with a maximum peak gain of 5.43 dBi. The antenna can be used for multi-frequency wireless communication applications.

“…With an overall size of 30 × 17 × 1.6 mm 3 , the desired performance has been achieved using a partial ground plane along with an inverted‐F shape and a 90° rotated counter‐clockwise M‐shaped structure. In Reference 13, a multi‐frequency antenna fabricated using FR‐4 substrate with dimensions of 56 × 44 × 1.6 mm 3 is presented. An inverted T‐shaped stub and two E‐shaped stubs are used to generate multiple frequency bands, enabling the antenna to cover 4G LTE, WiMAX, WLAN, and S/C/X‐band applications.…”

In this article, a compact planar heart‐shaped antenna based on countersink and partial ground plane techniques is proposed to operate as a multiband device for modern wireless systems. With a surface area of 28.5 mm2, the countersink technique (CT) has been developed to achieve high electromagnetic antenna performance. The CT consists of a particular multilayer configuration that uses two distinct materials where one of them with a radiating element on its top is placed inside another. In this article, a 508‐μm thick Rogers RO4350B with a radiating patch designed on its top is thermally embedded into a 1.524 mm thick FR4 HTG‐175. The slits are used to get multiband behavior, and their combination with the defected ground structure results in about 79.58% reduction in resonant frequency compared to the conventional antenna. A mathematical model is developed to predict the resonant frequency of the proposed antenna configuration. After modeling the heart‐shaped antenna with an electromagnetic simulator, its prototype was manufactured and validated through experimental measurements. The CT considerably improved the antenna's performance compared to the use of a single layer technology for the same antenna configuration. The return loss read from −10 dB shows that the proposed antenna covers multiple modern wireless applications, including LTE bands, 5G, WLAN, WiMAX, and Unlicensed National Information Infrastructure (UNII) radio bands. Furthermore, the antenna operates as narrowband and wideband simultaneously on its lower/middle and upper operating frequency bands. A close agreement is found between simulated and measured results across all the frequency bands.

“…Many methods for designing multi-band antennas have been reported in the previous literature, such as the resonator loaded slot multi-band antenna reported in [11], triple-band antenna design using annular ring reported in [12], multi-band antenna design based on Genetic Algorithm reported in [13], dual-band circularly polarized DRA (Dielectric resonator antenna) for sub-6 GHz reported in [14], multiband slot antenna design reported in [15][16][17], hexagonal gasket fractal multi-band antenna reported in [18,19], multi-band antenna design using Defected Ground Structure (DGS) reported in [20][21][22], and low profile multi-band PIFA antenna design reported in [23]. These antennas have many advantages, but there are some performances still to be improved, such as poor radiation properties (backside radiation, non-stable radiation for each band, large minor lobes), cost, and complexity for integration in circuits.…”

This article presents a T-Shaped Tri-Band (TSTB) antenna based on the Characteristic Mode Analysis (CMA) for satellite applications. Tri-band characteristics are achieved by exciting two orthogonal radiating modes for the L5-band and L1-bands, and one higher order radiating mode for the S-band. Initially, cavity model theory is applied to a rectangular antenna to calculate orthogonal modes (T M z 010 & T M z 001 ) at L5-band and S-bands, and these modes are validated using the CMA method. With the help of surface current study and modification of a rectangular antenna, the one higher order radiating mode and orthogonal modes are excited by using the CMA method. All desirable radiating modes are excited by a single coaxial feed line in full-wave simulation, which is based on FIT (Finite Integration Technique). The proposed antenna's measured operating frequencies are 1575 MHz (L1-band) for GPS (Global Positioning System) system, 1174 MHz (L5-band), and 2495 MHz (S-band) for IRNSS (Indian Regional Navigation Satellite System
