“…Several broadband applications have also been proposed in terahertz frequency range by the incorporation of lumped resistances in the equivalent circuit modelling . Split‐ring resonators (SRRs), being asymmetric in nature, are sensitive to the polarization orientation of incidence due to the gap in the SRRs . High reflection or high efficiency can be achieved in the design based on SRRs by adjusting the geometrical parameters of the structures.…”

“…To reduce the ohmic loss and enhance gain, the SRR‐based slots have been incorporated within the patch which behaves as a simple RLC resonator with some constructive and destructive couplings (RLC resonator is an electrical circuit consisting of a resistor (R), an inductor (L), and a capacitor (C), connected in series or in parallel) . The property of a metallic SRR depends on the plasma resonance frequency of the metal .…”

In this article, the performance of a meander-line-based microstrip patch antenna with split-ring resonator (SRR)-based slots and defected ground is analyzed at the terahertz frequency range. The designed antenna shows a multiband application within a frequency range of 3.77 to 6.60 THz and operates over six different frequencies (viz. 3.83 THz, 4.24 THz, 5.12 THz, 5.50 THz, 5.95 THz, and 6.50 THz). A maximum return loss of 37 is achieved over the band of 5.85 to 6.18 THz, while a maximum realized gain of 7.54 dBi and a total efficiency of 54% is obtained at 4.24 THz. The ground and radiating elements of the antenna are made of gold. Silicon dioxide is used as a substrate material. The antenna simulation is performed and reported in this study. The proposed antenna finds its applications in the detection of colon cancer, skin cancer, brain tumor, drug detection, and communication fields for point-to-point communication purposes.

“…SRRs are practicable in bandwidth enhancement, with their ability to couple strongly to other resonant elements. Antennas incorporated with SRRs for bandwidth improvements can exhibit diverse antenna performance characteristics depending on the configuration and position of the split in the SRRs [10][11][12][13][14][15].…”

This paper presents the effects of the position of the split of a split-ring resonator (SRR) on the performance of a composite broadband printed dipole antenna. The antenna is made of two printed dipole arms enclosed by two rectangular and identically printed SRRs. One dipole arm and the SRR are printed on the top side of the substrate, while the other dipole arm and SRR are printed on the bottom side of the same substrate. By changing the position of the split on the SRR, different antenna characteristic values are obtained, namely, for impedance bandwidth and radiation patterns. The split position is thus a critical parameter in antenna design, because it influences the antenna's major performance immensely. Different split positions and their consequences for antenna performance are demonstrated and discussed. The antenna generates linearly polarized radiations, and it is computationally characterized for broadband characteristics. The optimized compact antenna has overall dimensions of 9.6 mm × 74.4 mm × 0.508 mm (0.06λ × 0.469λ × 0.0032λ at 1.895 GHz) with a measured fractional bandwidth of 60.31% (1.32 to 2.46 GHz for |S11| < -10 dB) and a radiation efficiency of >88%.

In this article, a planar antenna with quasi‐isotropic radiation pattern is proposed for applications in drone communication. The proposed antenna consists of top‐loaded monopole and slotted loop antennas. The top‐loaded monopole provides a monopole‐like radiation pattern with a planar profile. To compensate for nulls in the monopole radiation pattern, a slotted loop antenna is added. Therefore, when two radiation patterns are combined, a quasi‐isotropic pattern is achieved with a low profile thickness of 7.2 mm. The performance of the proposed antenna is verified by simulation and experimental results. The antenna's 10‐dB impedance bandwidth is in the range of 2–2.4 GHz. The quasi‐isotropic radiation pattern is verified from both simulation and measured results.
