“…The isolation rate of the antennas in MIMO systems is based on the correlation of antennas to each other. We calculate the envelope correlation coefficient (ECC) of two possible states of parallel and perpendicular relations between two antennas based on the return loss of the proposed antenna [12] as follows:…”

“…* Correspondence: amin.honarvar@pel.iaun.ac.ir Due to the small size and low cost of such systems, there has been a surge of interest [4] in printed antennas. To cover multiple bands simultaneously, various antennas including a multiple mode monopole antenna, loop, and slot antenna have been proposed [4][5][6][7][8][9][10][11][12][13][14][15]. However, classic loop antennas are typically narrow band radiators that occupy much space.…”

In this article a thin hybrid multiband printed loop antenna is presented for application in multiple-input multiple-output (MIMO) systems. The proposed antenna has several advantages; for example, the pseudofilter feature of the proposed antenna is one of this antenna's advantages. Because of the antenna's width ( 9.5 mm), it can be used on the edges of the board. The first resonant frequency is generated by the original loop of the antenna. Incorporation of different embedded components, i.e. a subsidiary loop, extended ground-traces, parasitic patch, and the slits, results in the proposed antenna resonating as a multiband antenna. This antenna is adjusted in such a way that it resonant in WLAN ( 2.4 , 5.2 , and 5.8 GHz) and WiMAX ( 3.5 GHz) bands. Four antennas are used as a MIMO system that are sequentially and perpendicularly placed along the edges of the board. In conclusion, the antenna design is confirmed according to simulation results obtained from the constructed prototype and associated measuring results.

This paper proposes the integration of a dual‐band bandpass filter and antenna using a filter synthesis method. A dual‐mode perturbed patch resonator and a dual‐mode patch antenna are used in the implementation. The two patches are placed back‐to‐back to share a common ground. To increase the degree of freedom in controlling the channel bandwidths and to avoid radiation interference, a slot coupling technique is used to couple both patches. The patch resonator performs the signal splitting and combining function while the patch antenna contributes to the filtering poles and performs the radiating function. Good agreements have been achieved between the measurements of the prototype device and the simulations.

“…Split-ring resonators (SRRs) have been widely used to meet the design requirements of broadband capability, low profile, and compactness for electrically small antennas (ESAs) [1][2][3][4][5][6]. SRRs are generally made of two metallic concentric and coupled rings with slits on opposite ends.…”

This paper presents the effects of the position of the split of a split-ring resonator (SRR) on the performance of a composite broadband printed dipole antenna. The antenna is made of two printed dipole arms enclosed by two rectangular and identically printed SRRs. One dipole arm and the SRR are printed on the top side of the substrate, while the other dipole arm and SRR are printed on the bottom side of the same substrate. By changing the position of the split on the SRR, different antenna characteristic values are obtained, namely, for impedance bandwidth and radiation patterns. The split position is thus a critical parameter in antenna design, because it influences the antenna's major performance immensely. Different split positions and their consequences for antenna performance are demonstrated and discussed. The antenna generates linearly polarized radiations, and it is computationally characterized for broadband characteristics. The optimized compact antenna has overall dimensions of 9.6 mm × 74.4 mm × 0.508 mm (0.06λ × 0.469λ × 0.0032λ at 1.895 GHz) with a measured fractional bandwidth of 60.31% (1.32 to 2.46 GHz for |S11| < -10 dB) and a radiation efficiency of >88%.
