“…It can be seen that the proposed 8 × 8 array has the smallest effective radiating aperture electrical size (4.41λ × 3.95λ × 0.38λ) among those 8 × 8 millimeter-wave arrays due to the use of TE 340 -mode SICs based feeding network. Compared to the 32 × 32 array in [7] and the 16 × 16 array in [8], it can be inferred that larger arrays expanded from the proposed 8 × 8 array will achieve smaller effective radiating aperture electrical size. It is observed that the proposed design features the advantages of compact size, high gain, and high efficiency among the millimeter-wave LTCC antenna arrays.…”

“…However, the bulky size (antenna diameter is 450 mm) and large profile make it not suitable for integration with front-end planar circuits. In [7] and [8], a 32 × 32 and a 16 × 16 hollow waveguide based antenna arrays fabricated with a costly process called diffusion bonding are presented at D-band, respectively. These two arrays show the advantages of high gain (39.1 dBi and 31.7 dBi, respectively) and low profile (antenna array heights are 2.4 mm and 4.8 mm, respectively).…”

In this paper, a TE 340-mode substrate-integrated cavity (SIC) excited 2 × 2 slot antenna subarray with two TE 210-mode SICs' loading is presented at 140 GHz in low-temperature co-fired ceramic. By using the TE 340-mode SIC, the number of vias used in the feeding network and the area of the feeding network can be reduced compared to the feeding network composed of conventional TE 10 /TE 20-mode SIW power dividers. The proposed simplified and miniaturized high-order mode SIC-based feeding network leads to lower transmission loss and fabrication cost and reduces the fabrication difficulty. Each pair of radiating slots is loaded by a TE 210-mode SIC to improve the impedance bandwidth and the gain performance. For the proof of concept, an 8 × 8 antenna array is further designed and measured. The measured impedance bandwidth of the proposed 8 × 8 antenna array is 10.7% from 130.3 to 145 GHz for |S 11 | ≤ −10 dB. The measured peak gain is 20.5 dBi. The measured radiation efficiency is 59.2%. INDEX TERMS 140 GHz, low temperature co-fired ceramic (LTCC), TE 340 mode, TE 210 mode, substrate integrated cavity (SIC), slot antenna.

“…The channel capacity loss defines the maximum limit of the information transmission rate without significant loss. It should be <0.5 bits/s/Hzfor a well designed MIMO system to indicate lossless information transmission.The CCL parameter can be obtained by using equation (12) reported in [46]. Where a R indicates the correlation matrix at the receiving antenna.…”

A tree-shaped graphene based microstrip MIMO antenna for terahertz applications is proposed. The proposed MIMO antenna is designed on a 600×300 µm2 polyimide substrate. The designed MIMO antenna exhibits a wide impedance bandwidth of 88.14% (0.276–0.711 THz) due to the suggested modifications in the antenna configuration. The MIMO design parameters like total active reflection coefficient (TARC), mean effective gain (MEG), envelope correlation coefficient (ECC) and diversity gain (DG), Channel capacity loss (CCL) are evaluated and their values are found within acceptable limits. The proposed MIMO structure offers MEG ≤ -3.0 dB, TARC≤ -10.0 dB, DG≈ 10 dB, CCL < 0.5 bps/Hz/sec and ECC < 0.01 at the resonant frequency. At the resonant frequency, the isolation between the radiating elements of the proposed MIMO is recorded as -52 dB. The variations in operating frequency and S-parameters are also analyzed as a function of the chemical potential (µc) of the graphene material. The parametric analysis, structural design evolution steps, surface current distribution, antenna characteristics parameters and diversity parameters are discussed in detail in this paper. The designed MIMO antenna is suitable for high speed short distance communication, video rate imaging, biomedical imaging, sensing, and security scanning in the THz frequency band.

“…Circular polarisation is performed by arrangements of radiating elements and feeding network structures [10]. Many feed networks structures have been investigated to perform circularly polarized antenna such as Sequentially Rotated Feed [11,12], H-shaped aperture coupled feed [13] [14], and so on. In addition, number of feeding points required to produce circular polarisation waves also has been studied.Two fed network was implemented on two stacked substrates to feed with 180˚ phase shift to achieve CP [15].…”
