“…The high frequency generated by the rectangular slot should not interfere in both the bands, thus, it is important to take this frequency between the two bands. The resonant frequencies of higher modes generated by rectangular slots created in patch 1 can be changed by changing the slots' dimensions [33,34]. A PBG structure has been built on the ground plane to improve the desired bandwidth and other characteristics of the antenna.…”

A novel integrated compact antenna with photonic band gap (PBG) structure, having switching capability between lower and upper bands of 5G cellular communication is proposed. The proposed antenna can operate in the lower band (3.1 GHz to 3.5 GHz) as well as in the upper band (24 GHz to 27 GHz) of 5G cellular communication. Two radiating patches for the aforementioned frequency bands are developed in the same structure. A small patch for the upper-frequency band is inserted into a rectangular slot made in a large patch of the lower-frequency band. Both patches radiate at different times with the same ground. Two PIN diodes have been used to excite both patches at different times. The results indicate that the antenna has higher gain and wider bandwidth than the conventional antenna without a PBG structure. INTRODUCTIONWireless communication technology is evolving at a fast pace. 5G is a next-generation wireless communication technology, which provides support for very high speed data transfer. This technology would enable internet of things (IoT) and robotics applications to work effectively [1,2]. With 5G, an integrated compact antenna is required that can transmit and receive the signal within the proposed lower and upper bands. Along with the conventional lower band, 5G technology also works in an upper band (millimeter wave) to achieve a larger bandwidth, higher data transfer rate, and low latency. Many researchers have proposed 5G microstrip antennas for lower and upper bands respectively [3][4][5][6][7][8][9][10][11][12][13][14]. Recently, photonic band gap (PBG) structures have attracted the attention of researchers in antenna design due to the property of lattice periodicity in space. It is because it can efficiently suppress the surface waves and higher order harmonics. The conventional microstrip antennas have the disadvantages of lower efficiency and narrow bandwidth due to the effect of surface waves [15,16]. PBG structures provide stopbands, which eliminate the propagation of some frequencies, which affects radiation properties of antennas [17][18][19][20][21][22][23][24][25][26][27][28]. Zaidi et al. in [17] have designed a microstrip patch antenna at millimetre wave frequencies using a PBG cover and PBG substrate. They have reported gain improvement from 7.77 dB to 15.52 dB, but their reflection coefficient (S 11 ) has increased significantly from −31.24 dB to −17.26 dB. In [18], a design strategy using a PBG structure on ground plane is used to achieve wider bandwidth for patch antenna. The authors have reported an improvement in the impedance bandwidth from 3.72% to 31.9% at centre frequency 9 GHz after adding PBG on the ground plane. In [19,20], the works reported also show enhancement in gain and bandwidth. The works attempted so far in the literature are either in the low-frequency band or in the upper frequency band. Recently, a new class of antennas using metamaterials has attracted the interest of many researchers. These artificial materials can enhance the characteristics of miniaturized a...

“…The inference of the table is that Singh et al 31 designed the antenna which was operated at 1.43 THz, and the return loss of −34 dB was obtained. Hocini et al 14 and Sidhu et al 32 investigated the THz antenna structure and it produced the gain of 8.9 and 7.9 dB at the resonant frequency of 0.63 THz. Shahid et al 33 proposed a THz antenna and obtained the output of −34 dB return loss with gain of 6.8 dB.…”

SummaryNowadays, the wireless communication is improved in numerous ranges, and the use of the high speed of data rate in the communication systems is needed. The standing problem of high‐performance planar antenna is reduced by the recently developed artificial dielectric called photonic crystal, which is used to control and manipulate the optical property of light. This paper addresses the slotted tube antenna structure, and the investigation is done by the concept of triangular lattice structure based on the photonic crystal. This utility enhances the return loss of −57.81 dB and the voltage standing wave ratio (VSWR) of 1.002 at 2.37 THz operating frequencies. The increase in hole radius provides the shifting in zero dispersion point towards the shorter wavelength that helps for faster data rate transmission applications. Further, to characterize the model of the proposed antenna, the optimal value of the air hole, lattice constant value between holes and the thickness of the slot are found and the related parameters of such antenna are studied with the support of simulation software CST microwave studio.

“…This motivated the authors of this paper to design and analyze a compact microstrip MIMO antenna with wide impedance bandwidth and better diversity performance for high speed short range wireless communication systems in the THz band. In this paper, the authors have designed a two-element spatial diversity multiple-input multiple-output (MIMO)THz antenna which occupies less area and offers much better impedance bandwidth compared to the reported single element antennas [25][26][27][28][29][30][31][32], array antenna [33] and MIMO antennas [34][35]. The reason behind the selection of spatial diversity MIMO antenna is to exploit its multipath characteristics to provide high data rate, better channel capacity, interference mitigation, extended coverage, and improved signal reliability by avoiding fading.…”

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.
