In this paper, a quad-port multiple-input multiple-output (MIMO) semitransparent antenna is designed for automotive applications. The transparent soda lime glass substrate is used in the prototype antenna for windshield applications, and the radiator is nontransparent copper metal. The unit cell radiator of the MIMO antenna is similar to the “NISSAN automobile-like” logo. The proposed MIMO antenna has a −10 dB impedance bandwidth of 3.4 to 11 GHz. The edge-to-edge distance between the elements in the MIMO configuration is 6 mm. The antenna elements are perpendicularly oriented to offer dual (horizontal and vertical) polarization, which aids in providing better isolation and good signal reception in all directions. The isolation between the resonating elements is greater than 15 dB without the use of any decoupling structure. The diversity metrics are examined in order to gain a better understanding of the MIMO antenna performance. The envelope correlation coefficient (ECC) is less than 0.01, diversity gain (DG) is greater than 9.98 dB, and the total active reflection coefficient (TARC) and channel capacity loss (CCL) are less than −10 dB and 0.07 bits/s/Hz, respectively. The quad-port MIMO antenna offers transparency of 52.26% over the entire area. The proposed antenna could be suitable for automotive applications such as intelligent transportation systems (ITS), vehicular communications, and the automatic vehicle identifier (AVI).

In this article, a symmetric split ring resonator (SRR) based metamaterial (MTM) is presented that exhibits three resonances of transmission coefficient (S21) covering S, C, and X-bands with epsilon negative (ENG) and near zero index properties. The proposed MTM is designed on an FR4 substrate with the copper resonator at one side formed with two square rings and one circular split ring. The two square rings are coupled together around the split gap of the outer ring, whereas two split semicircles are also coupled together near the split gaps. Thus, gap coupled symmetric SRR is formed, which helps to obtain resonances at 2.78 GHz, 7.7 GHz and 10.16 GHz with desired properties of the MTM unit cell. The MTM unit cell's symmetric nature helps reduce the mutual coupling effect among the array elements. Thus, different array of unit cells provides a similar response to the unit cell compared with numerical simulation performed in CST microwave studio and validated by measurement. The equivalent circuit is modelled for the proposed MTM unit cell in Advanced Design System (ADS) software, and circuit validation is accomplished by comparing S21 obtained in ADS with the same of CST. The effective medium ratio (EMR) of 10.7 indicates the compactness of the proposed MTM. A test antenna is designed to observe the effect of the MTM over it. Numerical analysis shows that the proposed MTM have an impact on the antenna when it is used as the superstrate and helps to increase the gain of the antenna by 95% with increased directivity. Thus, compact size, high EMR, negative permittivity, near zero permeability and refractive index makes this MTM suitable for S, C and X band applications, especially for antenna gain with directivity enhancement.

“…Recently, coplanar waveguide (CPW) feed has become increasingly popular due to its multiple advantages like uniplanar structure, wide bandwidth, etc. CPW fed MTM based patch antennas exhibit very good performance with reduced size [7,8]. Efforts have been taken to prove that the antenna dimensions can be further reduced by using ACS feed which is a modified version of conventional CPW feed [9][10][11].…”

The design of a Complementary Split Ring Resonator (CSRR) embedded compact Asymmetric Coplanar Strip (ACS) fed monopole antenna is presented in this paper. By incorporating the ACS feed, a substantial reduction of 27% in antenna dimensions is achieved. Further miniaturization of 68.6% is obtained by embedding CSRR on the designed patch and a trapezoidal ground. The overall size of the antenna is 13.2 × 27 × 1.6 mm 3 , and it is printed on an FR4-epoxy substrate. The antenna operates with a resonant frequency of 3.6 GHz and a bandwidth of 3.3 GHz (3.2-6.5 GHz). Thus it is appropriate for sub-6 GHz 5G applications. It exhibits a return loss of −28 dB and a gain of 2.8 dB at the resonant frequency. The antenna is fabricated, and the measured results match well with the simulated ones. Being a simple, cheap, and uniplanar structure, the proposed antenna can meet the requirements of a modern wireless communication system.
