“…As illustrated in Figure 2A, to equalize the position of the antenna resonant frequency and the notch frequency of the band-stop filter and place them at the frequency of 10 GHz, the best value for p y is achieved as 3.93 mm (0.131 k 0 ). In this case, according to (2) and (3), p y is:…”

“…As a result, the performance of the array antennas is considerably degraded due to strong mutual coupling between neighboring elements. 1,2 Recent researches show that the mutual coupling may seriously reduce the output signal-to-interference-noise ratio 1 and efficiency 3 of an adaptive-array antenna, and the convergence of array signal processing algorithms, 1 and impacts the mean capacity and correlation of a MIMO system. 1,3 Therefore, mutual coupling reduction is an important issue in the systems mentioned above.…”

A very closely‐spaced 2 × 1 microstrip‐patch array antenna is proposed for present and future modern compact array systems. Between the antennas, a novel isolation structure developed from two parasitic L‐shaped strips with only one via for each one is presented to reduce the mutual coupling more than 53 dB at the resonant frequency in 10 GHz in comparison with the conventional array without any isolators. Unlike the other methods, this isolator has a simple and cost‐effective structure with a good performance, low destructive effects on the radiation and resonance position, low design and fabrication complexity, and simple optimization method which can notably block the surface and space waves between the antennas. Simplified semi‐analytical expressions and a guided‐wave‐length‐based parametric study are conducted on key geometrical parameters of the isolator circuit model to determine their effects on the overall behavior. To validate the technique and present its advantages, the final design has been fabricated, measured, and compared with the selected recently proposed suitable works. A good agreement was also achieved in comparison with the simulated results.

“…The power of this terahertz antenna is fed through the feed line in the optical range having an impedance of 50.06 Ω so that it is convenient to feed by SMA connector of 50 Ω impedance . The resonant frequency and other characteristics mainly depend upon the horizontal and vertical length of the meander line along with the separation between the twist arms, wire width, and the total physical length of the antenna . Besides that, the resonant frequency is also controlled by the shapes and dimensions of the SRR, which are the functions of capacitance and inductance .…”

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.
