“…However, they are less desirable for millimeter wave applications because of their curvature shape and bulky size. Due to their flexibility in design and lightness in weight, microstrip patch structures have been widely focused in the antenna design [4][5][6][7]. A linear active microstrip patch array is utilized to feed a lens antenna in order to improve the antenna gain and the power amplification capability for the Ka-band satellite communication system [8].…”

In this paper, a new design of high gain and wide bandwidth microstrip patch antenna array containing double meander dipole structure is proposed. Two in-phase resonant frequencies in the Ku-band (12–18 GHz) could be achieved in the double meander dipole array structure, which lead to enhance impedance bandwidth without costing extra design section. Besides, further enhanced gain of 2 dBi of the array over the entire operating frequency range has been achieved by introducing a double-layer substrate technique. The proposed antenna has been fabricated using the E33 model LPKF prototyping PCB machine. The measurement results have been performed, and they are in very good agreement with the simulation results. The measured –10 dB impedance bandwidth indicates that the array provides a very wide bandwidth which is around 30% at the center frequency of 15.5 GHz. A stable gain with a peak value of 10 dBi is achieved over the operating frequency range. The E- and H-plane radiation patterns are simulated, and a very low sidelobe level is predicted. The proposed antenna is simple and has relatively low-profile, and it could be a good candidate for millimeter wave communications.

“…Some other feeding networks like single feed, off‐centered microstrip integrated with DRA and modified microstrip feed network DRA are capable of offering circular polarization. In Reference higher order circular polarized DRA, DRA with Fabry Perot high‐Gain circularly polarization, DRA array fed by the Cavity‐Backed SIW, high gain self‐package used in DRA have been explored. Recently reconfigurable circular polarized liquid dielectric resonator and a low profile multilayer cylindrical segment fractal DRA have been investigated for wideband applications.…”

In this article, cylindrical segmented dielectric resonator antenna (CDRA) is proposed for ISM band applications. To obtain the proposed antenna, three different (120°, 60°, and 30°) segments of different cylindrical radius r1, r2, and r3 with stacked angular displacement are used for circular polarization with wideband frequency response. Quadrature phase shift of orthogonal field are observed when segment of cylinder is stacked with specific angular displacement. Various higher order modes are investigated. The simulated and measured impedance bandwidth of the proposed antenna is 90% (3.3 GHz‐8.7 GHz) and 83.4% (3.5 GHz‐8.5 GHz) respectively and the simulated and measured axial ratio bandwidth is 53.8% (3.8 GHz‐6.6 GHz) and 58.5% (3.5 GHz‐6.4 GHz), respectively. Proposed antenna attains 7.1 dBi measured peak gain at 8.5 GHz with more than 80% radiation efficiency in the frequency band. The fabricated prototype is experimentally measured and its results are found to be commensurable with the simulation results.
