“…11, shows the antenna provides a gain better than 10 dBi over 3.15-3.9 GHz, but the gain is significantly enhanced in the range of 3.6 to 3.9 GHz with a maximum gain of 12.65 dBi at 3.73 GHz. Table I shows the advantage of the proposed gain-enhancement technique compared to other conventional methods [5][6][7][8]. The Eand H-plane radiation pattern of the antenna for the 4×5 array of EECSR at 3.8 GHz is plotted in Fig.…”

This paper presents a high-gain Bow-tie antenna for applications in next generation base-stations operating from (2.5-3.9 GHz). The proposed structure consists of three circular sector patches that are attached laterally to the microstrip feed-line, which is etched on both sides of the common dielectric substrate to create symmetrical Bow-tie antenna. By loading the antenna with a 2×5 array of enhanced end-coupled split-ring (EECSR) unit-cells results in significant enhancement in the antenna gain performance. This is because the EECSR unit-cells behave as parasitic radiators, which is analogous to Yagi-Uda antennas. The EECSR unit-cells provide a medium of high effective permittivity that effectively reduces the spacing between parasitic directors. As a consequence, a compact and miniature structure is achieved compared to conventional quasi Yagi-Uda planar designs. The dimension of EECSR unit-cell is 33 × 36 mm 2 with inter-element spacing of 0.075 at 3.5 GHz. A prototype of the antenna was fabricated and its performance measured to validate the simulation results. The measured peak gain of the antenna with 4×5 array of EECSR is 12.65 dBi at 3.73 GHz, constituting a peak gain enhancement of 7.45 dBi in the WiMAX band compared to an equivalent conventional Bow-tie antenna.

Abstract-An antenna concept for compact millimeter-wave radar sensors that desire a fan-beam radiation pattern is proposed. It combines an end-fire antenna on a ceramic substrate with a cylindrical parabolic reflector that can be integrated in the sensor's metal housing. The concept allows a direct interconnection from the active components to the antenna in a flip-chip attachment. It is validated with a 77-GHz Yagi-Uda antenna on a 127-m thick Alumina substrate by measurements with a probe-based measurement setup. The measured return loss, gain, and radiation patterns of the antenna without and with the reflector are given.Index Terms-End-fire antennas, millimeter-wave antennas, millimeter-wave radar, radar antennas, reflector antennas.

A new small high-gain wideband rectangular patch antenna is proposed in this paper. The antenna has a simple structure where the dimensions are about 11 mm by 7 mm by 1.58 mm leading to a good bandwidth. The antenna structure is optimized and simulated using electromagnetic commercial software, and the measured bandwidth defined by return loss <−10 dB is 1.97 GHz from 10.94 to 12.91 GHz for simulated results and 2.75 GHz covering from 10.8 to 13.55 GHz for measured results using vector network analyser. The gain is up to 4.91 dBi with a good radiation pattern. The comparison between simulation and measurement results permits to validate the structure of the proposed antenna. The low expenses of this profile and its simple configuration allow for an easy fabrication process, with usability in many applications such as radar, satellite and wireless communication.
