In this work, using characteristic mode analysis, a multi-layered nonuniform metasurface structured antenna has been optimized. The driven patch of square structure and the parasitic elements circular radiating cross-slotted meta-structure are used in proposed model. modal significance angles surface currents analyzed based on to optimize structures. is resonating between 5.5–6.1 GHz, covering ...

This study aims to design a circularly polarized compact antenna using characteristic mode analysis (CMA). The proposed consists of substrate with slotted annular ring-shaped patch and partial ground. excitation position the its optimal dimensions are determined through different operation modes CMA. After that, an optimized is designed, prototype fabricated for validation. experimental results...

This paper presents a novel defected ground structure-based slotted circular patch antenna for mm-Wave application. A with compact size of 10 mm×8 mm×0.75 mm is fabricated in the lab. The designed has 2 GHz impedance bandwidth that covers frequency range 42GHz to 44GHz. It achieves directional radiation pattern millimeter-wave applications and maximum realized gain 6 dBi at operating 42.65 GHz....

A new metasurface superstrate structure (MSS)-loaded dual band microstrip line-fed small patch antenna is presented in this paper. The proposed antenna was designed on a ceramic-filled bioplastic sandwich substrate with a high dielectric constant. The proposed 7 × 6 element, square-shaped, single-sided MSS significantly improved the bandwidth and gain of the proposed antenna. The proposed MSS i...

This article proposes a wideband differentially fed dual-polarized magnetoelectric (ME) dipole for millimeter-wave (mm-Wave) applications. Various electric and magnetic characteristic modes of slotted patch antenna are investigated utilized effectively to create stable broadside radiation pattern, covering fifth-generation (5G) frequency bands from 24.25 40 GHz. To implement this, the lifted gr...
