This paper explains the design and development of an electrically small (ka = 0.59) circularly polarized (CP) antenna based on vialess composite right/left‐handed (CRLH) transmission line (TL) and third‐iterative fractals (TIF) applicable for 1.637 GHz L‐band mobile satellite applications. The idea behind the CP antenna originates from the combination of curved meander line inductor on the top side of the substrate back coupled with TIF in backside of the substrate. The loading of TIF provides an increased level of cross polarization by adjusting the dimensions of TIF which is almost equal to the main polarization level of original CRLH‐TL loaded antenna on the top side of the substrate. Due to this, the antenna can generate two orthogonally polarized modes for supporting CP radiation with excellent miniaturization and improved gain. The overall dimensions of the proposed antenna are 22 × 27 × 1.27 mm with radiating element size including the ground plane are 0.11λ0 × 0.14λ0 × 0.006λ0 at 1.635 GHz. The proposed antenna can provide excellent miniaturization of 68.51% compared with the conventional monopole antenna with improved radiation performance. The antenna provides an acceptable impedance bandwidth of 0.73%, improved gain of 1.79 dBi without using complex vias, excellent miniaturization, and low profile (0.006 λ0) compared to existing similar type of antennas in the literature.

Four iterations of a Coplanar Waveguide (CPW)-Fed KOCH SNOWFLAKE fractal antenna are studied. Increasing the number of iterations allow us obtaining a simple and miniaturized antenna with good performances, operating for Ultra Wide Band (UWB) applications.The proposed antennas are a good solution for the 3.7-4.2GHZ C-Band, the 5.15-5.82 Wireless Local Area Network (WLAN), and for the 5GHZ Worldwide Interoperability for Microwave Access system (WIMAX) applications. The simulation was performed in FEKO 6.3.

“…Furthermore, the latter has been extensively implemented for the purpose of antenna miniaturization since its resonance frequency is independent of actual physical size of the antenna and merely determines by distributed element values of transmission line (TL). However, ZOR antennas suffer from narrow bandwidth and low radiation efficiency [2][3][4][5]. Various ZOR antennas with enhanced bandwidth and efficiency have been proposed in [6][7][8][9][10][11][12].…”

Abstract-A low-profile bandwidth-enhanced zeroth-order resonant (ZOR) antenna based on composite right/left-handed transmission line (CRLH-TL) theory loaded by parasitic element is presented in this paper. The bandwidth and efficiency of the proposed ZOR antenna is improved simultaneously by introducing a parasitic element resonating within the CRLH-TL band-stop. The dispersive behavior of the ZOR antenna is analyzed by performing full-wave simulation using CST microwave studio and compared with the theoretical circuit model. The overall dimensions of the proposed antenna is 0.303λ 0 × 0.248λ 0 × 0.003λ 0 . The antenna has been fabricated and tested. The experimental results exhibit wide operational bandwidth of 87.1% and excellent radiation efficiency up to 95.7%. Owing to the symmetrical configuration of the proposed design the polarization purity better than −14 dB is obtained. The measured results are in very good agreement with the simulation. The compact, uni-planar and via-less configuration of the proposed antenna with reasonable polarization purity makes it desirable to be used for modern wireless communication systems such as GSM, UMTS, WiMAX, WLAN and LTE.
