A proximity-coupled graphene patch-based full-duplex antenna is proposed for terahertz (THz) applications. The antenna provides a 10 dB impedance bandwidth of 6.06% (1.76 − 1.87 THz). The input ports of the proposed design are isolated from each other by −25 dB. The aspect ratio of the graphene-based radiating patch and the physical parameters of the antenna is selected for obtaining the single-mode operation. The dimensions (length and width of graphene) of the proposed antenna have been opted to operate in two higher-order orthogonal modes, and these modes remain intrinsically isolated. The utilization of the graphene material provides flexibility in tuning the antenna response. Graphene-based patch exhibits good electrical conductivity, electrical conductance controllability, and plasmon properties. The graphene-based antennas perform better than their metallic counterparts, especially in the THz frequency range. The radiation properties of the graphene material are more prominent due to no-ohmic losses. Moreover, its chemical potential may be altered by applying a bias voltage to its surface conductivity, which modifies the surface impedance value of graphene. Therefore, with a small footprint, graphene acts as an excellent radiator at extremely high frequencies.

A 4 × 4 patch array antenna based on loading shorting vias is proposed in this letter. The excitation method of the array antenna adopts stripline coupling feed, leading to a strong mutual coupling between the adjacent elements. The realized gain and impedance match are deteriorated seriously. Then, eight groups of metallic vias are introduced to the array antenna. By adjusting their number and spacing, the radiation performance of the array antenna can be improved significantly. Finally, the experiment results show that the proposed array antenna resonates at 5.4 GHz. Compared with the antenna without shorting vias, one resonance point caused by the mutual coupling can be removed within 5.34 GHz to 5.46 GHz. The gain drops unexpectedly, which is improved as well.

“…Wireless communication channel environment is a densely populated area as the links are more susceptible to fading and co-channel interference, hence, due to this reason, power falls substantially with space. us, it becomes challenging for the antenna designer to design a system with higher spectral e ciency, higher quality of service, and wide bandwidth [1][2][3][4].…”

Here, a compact, dual band, 4-elements multi-input and multi-output (MIMO) antenna diplexer is designed to use in wireless local area network (WLAN) applications. The antenna is accomplished in a planar profile by employing Substrate Integrated Waveguide (SIW) technology. To reduce the size of a single element by 75%, a quarter-mode substrate integrated waveguide (QMSIW) technology is introduced. The QMSIW is realized by bisecting the full-mode SIW along the two magnetic walls and considering the quarter-mode for the operation. Initially, two-QMSIW cavities of distinct dimensions are designed to operate in two frequency bands, 5.2 GHz and 5.8 GHz, respectively. Later, two more radiating elements operating at the same frequencies are integrated with a 2-elements antenna. For better polarization decoupling, the identical elements are placed perpendicular to each other, and a parasitic metallic strip loaded with shorting vias is placed between two identical frequency antenna elements; hence, the port isolation is improved up to −25 dB. The antenna covers a bandwidth of 1.8% in the lower frequency band while 2.2% in the upper frequency band. The antenna prototype is fabricated, and its results are verified with experimental data. It is observed that the measured results are closely following the simulated results.
