“…To achieve the different goals of a MIMO array, different proposals have been made to reduce the size, by using geometries [1] and element interconnections [2]. On the other hand, to increase the electromagnetic isolation, several proposals have been published, including slots and shorting pins [3], Defected Ground Structures [4,5], electromagnetic barriers, and imperfect structures, among other techniques.…”

In this paper, a very small 4-port MIMO antenna is designed, based on a metamaterial structure composed of embedded octagonal Split-Ring Resonators (SSRs). The antenna array shows an axial symmetry configuration with dimensions of 32 × 32 mm 2 , corresponding to 0.157λ 2 , approximately, related to a center frequency of 3.5 GHz, with a high electromagnetic isolation despite the radiators' closeness, reaching values bigger than 26 dB for adjacent antennas, and more than 28 dB for opposite antennas. The antenna is built on a substrate with dielectric permittivity of 2.2 and 1.27 mm thick. The Total Active Reflection Coefficient (TARC) presents a steady behavior for different random phases at the incoming signals, keeping a system bandwidth of 0.9 GHz for a −10 dB value. On the other hand, the Envelope Correlations Coefficient (ECC) reports values lower than 0.001 in all the antenna relationships, achieving a very uncorrelated performance of the electric fields in each element. The radiation pattern is quasi-omnidirectional, obtaining a low gain around −2 dBi, a trade-off that is considering the size reduction of the MIMO antenna.

“…A thorough literature review demonstrates that low SLL printed antennas 2–16 and waveguide‐based slot array antennas 17–22 are usually employed for various microwave and mmWave applications. In Chopra and Kumar, 7 series‐fed printed antenna arrays are proposed by tapering the width of the radiation element to achieve an SLL of less than −28 dB.…”

In this paper, the design of a low sidelobe level (SLL) 10 × 10‐element series‐fed patch antenna array is presented. A ridge waveguide‐based nonuniform feeding layer is employed to excite the array. Each column of the antenna array includes a tapered 10‐element series fed patch antenna array. By using a simple and compact center‐fed ridge waveguide, a low loss feeding layer is achieved. The coupling between the ridge waveguide and the standard WR‐75 flange is performed by employing a proposed stepped transition. The measured results indicate that the maximum gain is 24.1 dBi and the SLL is lower than −20 dB in both H‐ and E‐planes at 12.7 GHz. The proposed low SLL planar series‐fed patch antenna array can be utilized as an acceptable candidate for radar applications.
