In this work, an array of circular patch antenna loaded with a partial split ring and a pair of stubs each with same dimensions, on each of the antenna is designed to operate in the LTE band with wide bandwidth. The split ring not only accounts for a newer operating band, but also tend to reduce the isolation and the stubs tends to increase the bandwidth which results in change by 44.92 % compared to array of antennas without split rings. It has a compact substrate dimensions of 55 × 30 × 0.8 mm 3 and ground of 55 × 9 mm 2 . The proposed antenna is simulated using high frequency structural simulator (HFSS) and fabricated. The measured results are in compliance with the simulated results. The proposed antenna find applications in

“…For this reason, many efforts have been made for compacting the antenna dimensions. Various techniques have been introduced for size reduction of MPAs such as using shorting pins and shorting plates, utilizing fractal antennas, cutting slots in the radiating element [3][4][5][6]. In addition to these methods, loading the antenna by metamaterial structures, including split ring resonator (SRR) and CSRR, provides new ways to achieve higher level of size reduction [7][8][9][10].…”

Abstract-In this paper a compact wideband aperture coupled microstrip patch antenna (MPA) with impedance bandwidth of 26.3% is designed. Size reduction of the radiating element and the slot in the ground plane is achieved by incorporating an interdigital capacitor (IDC) in the patch and a complementary split ring resonator (CSRR) close to the slot which offers composite right/left-hand (CRLH) antenna. An interdigital capacitor in the patch acts as series left-hand component, and the slot together with the CSRR in the ground plane acts as a left-hand parallel inductor. By this technique, the patch and slot dimensions compared with the initial designed antenna are reduced about 26.2% and 30.2%, respectively. Through cutting CSRRs with different arrangements in the ground plane, a dual frequency band antenna is designed. Finally, a compact wideband circularly-polarized (CP) MPA is proposed through imposing various perturbations in the current route in the ground plane of the antenna. The maximum gain and the impedance bandwidth of the designed CP antenna are 8.4 dBi and 25%, respectively. Two designed antennas are fabricated and tested. The measurement results confirm the simulation ones.

“…However, narrow impedance bandwidth is an inherent property of such conventional printed circuit antennas. Among several techniques that have been applied to enhance the microstrip antenna performance, coplanar transmission lines coupled to parasitic patches through gaps were suggested in [2][3][4][5] to increase the antenna bandwidth. However, the results from this technique showed that the antenna bandwidth cannot be enhanced more than few tens of a percent [6].…”

Abstract-In this paper, the design of a printed circuit antenna based on lotus flower patch of a miniaturized profile is proposed. The antenna consists of three layers including a patch and a ground plane of a thin copper layer separated by a Roger RT/duroid R 5880 substrate for high gain-bandwidth product applications including microwave imaging systems. The patch structure is patterned with triangular defects to provide a fractal structure. Nevertheless, the ground plane is defected with Electromagnetic Band Gap (EBG) structures. The antenna is found to show a first resonant mode around 3 GHz, while the other frequency modes are obtained around 4.2 GHz and 6 GHz which are below −10 dB. Moreover, the antenna operates over the frequency range from 7.8 GHz up to 15 GHz with a bore-sight gain varing from 4 dBi up to 6 dBi when operates in free-space environments. The antenna size is reduced to a 32 mm × 28 mm × 0.5 mm using shorting plates on the substrate edges. The antenna performance characteristics are examined using CST and HFSS commercial software packages, which are based on the Finite Integration Technique (FIT) and the Finite Element Method (FEM), respectively. Finally, the antenna performance is tested experimentally for both S 11 spectrum and radiation patterns to show an excellent matching with the obtained numerical results.
