“…A CP microstrip antenna featuring a T-shaped slot on the patch and a high-impedance resonant EBG (HREBG) surrounding the substrate has been developed, yielding an axial ratio (AR) bandwidth of 330 MHz. Upon incorporating eight unit cells of HREBG, a substantial improvement in both impedance bandwidth, with a widened range of 920 MHz, and peak gain, which increased to 5.93 dBi, was observed [16]. This study's primary achievement is the development of an inset-fed rectangular microstrip patch antenna, which incorporates a defective slotted section loaded with a Complementary Split Ring Resonator (CSRR) ground plane.…”

In this work, the proposed design utilizes a complementary split ring resonator (CSRR) loaded ground plane to enhance the return loss of a microstrip patch antenna.The addition of CSRR slots on the ground plane resulted in an improvement in the return loss of the microstrip patch antenna. The proposed antenna has undergone the stages of design, fabrication, and testing. The measured results exhibit a high level of conformity with the simulation results. The proposed antenna has a size of 99 × 55 × 1.6mm 3. The measured impedance 1 Springer Nature 2021 L A T E X template A Compact Metamaterial Loaded MIMO Antenna for Sub-6GHz 5G Applications bandwidth is 24.18 (return loss< −10 db) from 3.29 to 4.2 GHz. The designed antenna is suitable for applications within the Industrial Scientific Medical(ISM) band. The H-plane radiation pattern of the antenna was directional, while the E-plane radiation pattern was bidirectional. To achieve optimal outcomes, a parametric investigation of the CSRR was conducted. Alternatively, researchers carried out a study on various parameters of the CSRR to determine the most favorable results. The proposed antenna exhibits a straightforward design, displays a desirable radiation pattern, and boasts a gain of 2.63 dBi when operating at its resonant frequency. Additionally, a size reduction of 10% was attained without compromising its performance, and the bandwidth slightly surpasses that of the unloaded antenna.

“…However, this led to an increase of the overall size of the antenna. In [24], a high-gain compact CP slot antenna at 5.1 GHz was proposed with hexagonal ring-shaped EBG on the substrate with an impedance bandwidth of 18%. Recently, EBGs have been implemented as metasurfaces [25, 26] to enhance the performance of CP antennas.…”

This study investigates a low-profile circularly polarized (CP) antenna using coplanar waveguide feeding. Rectangular-shaped slots and an inverted L-shaped slit are entrenched into the ground plane to enhance the impedance bandwidth of the antenna. Furthermore, the antenna is implemented with six elliptical electromagnetic band gap structures on its substrate to enhance the −10 dB return loss bandwidth and also to generate CP waves. The experimental and theoretical results closely match each other and indicate that a simple and compact design antenna with dimensions of 0.317λ0 × 0.317λ0 × 0.023λ0(λ0 is the operating wavelength at 4.74 GHz in free space) achieves 36.9% (3.91–5.68 GHz) of the −10 dB return loss bandwidth and 9.98% (4.09–4.52 GHz) of the 3-dB axial ratio bandwidth, thus making it a favorable entrant for radio altimeter and wireless avionics infra-communication systems.

“…Dipole wired antennas, aperture antenna, horns, and microstrip antennas are among the famous antenna types [2]. Methods of improving the performance of microstrip antennas include the design of array structure [3], the use of special materials such as graphene [4], the employ of metamaterials, metasurfaces, and electromagnetic bandgaps (EBG) [5][6][7], substrate integrated waveguide (SIW) [8], ridge gap waveguide metamaterial and metasurface structures in millimeter-wave and terahertz frequency bands, are an efficient tool [14]. Most of the authors' work in recent years has been the design of metamaterial-based antennas and components [14][15][16][17][18][19].Very recently, in [17], the authors have improved the gain of a microstrip antenna in the millimeter-wave frequencies by more than 11.5 dB, compared to the antenna without any metamaterial structures.…”
