“…At the resonance, the MTM array of CSRRs has a negative permittivity and inhibits signal propagation. Indeed, the propagation constant is purely imaginary so all the waves which pass across the structure are evanescent waves [17,19,20]. Besides, the arrays of CSRRs are more suitable for application in low profile planar antenna arrays to improve the bandwidth of the decoupling effects and enhance their performances.…”

Abstract-This paper proposes an efficient microstrip isolator filter which suppresses the surface and lateral waves (SW and LW) in planar antenna arrays. The structure consists in a double or triple row of periodic and flipped array of subwavelength Complementary Split Ring Resonators (CSRRs). The array of CSRRs is etched on a dielectric substrate backed by a metallic ground plane. These structures can both block the electromagnetic (EM) energy in one direction and guide it along the other transverse direction. In particular, the flipped array of CSRRs presents wider bandgap characteristic (stopband ≥ 20%) than periodic array of CSRRs (∼ 16%) and conventional array of SRRs (≥ 12%). Then, the metamaterial filter is inserted between two 6.1 GHz probe-fed patch antenna elements separated by a distance of 0.8λ 0 . Excellent agreements between the simulated and the experimental results are obtained. In fact, a significant reduction of the EM mutual coupling is achieved, more than 24 dB, over a wide frequency bandwidth. Moreover, the proposed CSRR structures are compact, low complex and, as printed antennas, are very easy to manufacture. They have numerous applications in MIMO systems and directive phased arrays.

“…Thanks to these properties many compact and multi-band antennas have been realized, especially at low microwave frequencies, using CRLH TLs. Based on CRLH TL, many ultra-compact multi-band antennas [10][11][12][13][14][15][16] and bandstop filters [17,18] have been reported. Also, some different design integrated filtering antennas have been presented in [19][20][21][22].…”

Abstract-This paper presents an ultra-compact filtering integrated antenna for GPS (1.57 GHz) and LTE (2.65 GHz) applications. The antenna comprises integration between dual composite right/lefthanded antenna and bandstop filter in one platform. The whole integrated antenna size is only 30 × 28.5 mm 2 . Compared to conventional antenna with the same dimensions, the proposed antenna is only 6.5% at GPS band and 16.5% at LTE band. The deign procedures of individual antennas, bandstop filter and the filtering integrated antennas are explained in details. The full wave simulations supporting the design procedures and experimental measurements for all introduced components are introduced with good agreement. Finally, as a consequence of the proposed antenna ultra small size and its filtering capability, the antenna is a good candidate for implanted antenna applications.

“…This has helped the electromagnetic researchers with more design capabilities than conventional (right handed) transmission line. Accordingly, CRLH TL has been used in introducing many compact and multi-band microwave components [9][10][11][12], to name some examples such as impedance transformers [13], power divider [14], resonators [15], filters [16], couplers [17], radar absorber [18].…”

Abstract-In this paper, a nonlinear phase enhancement of multi-resonance composite right/lefthanded unit cell for multi-band antennas is presented. Different antennas with nonlinear enhanced phase which can operate up to five different frequency bands are introduced. Meanwhile, the proposed antennas have compact size so that they can demonstrate size reduction up to 60% compared to conventional patch antennas operating at the same frequencies. The achieved phase enhancement has been validated by comparing two different configurations of composite right/left-handed cells. The analysis, electromagnetic full wave simulations and experimental results are discussed. A reasonable agreement is achieved between the measured and simulated results.
