“…They have demonstrated and evaluated the performance of embedded printed antenna arrays in linear and planar geometries, and tested their performance outdoors, as shown in [23,24]. In addition to UAVs, the group also worked on some automotive applications for direction fi nding, where they came up with printed antenna structures with small sizes for vehicular direction-fi nding systems [25,26]. Algorithms for sidelobe suppression and antenna-pattern shaping have also been investigated and proposed by the group at KFUPM [27,28].…”

“…In addition, the switched‐beam array, 11 which is composed of 12 inverted‐F antennas, suffers from a poor port isolation. Using the V‐shaped dipoles 12 and slot antennas 13,14 to compose the circular array also suffers from similar problems. To further improve performance, broadband antennas are used as the circular array element 15–17 .…”

A switched‐beam circular array with ultra‐wideband ridged horn elements is proposed in this letter. To obtain stable radiation patterns in a broadband as well as in a large coverage in the elevation plane, the electromagnetic fields in the ridged horn antenna are analyzed by the mode decomposition method. Based on the analysis, the rear of the ridged horn is cut. Besides, the ridge extension, out of the horn aperture, serves as a transformer from the horn to the free space for the downward radiation caused by the horn aperture asymmetry. The simulated results show that the circular array can obtain omnidirectional beam coverage in the range of θ = 50°–100° from 2.2 to 5.9 GHz, with the S11 below −10 dB and the gain higher than 5 dBi. The performance of the proposed antenna is validated by experiments.

“…Thus following the traditional approach that has high complexity and cost. Three other examples that showed switched beams or sectoral radiation patterns were proposed in [7]- [9]. In the former, slot antennas were used and operated in the 2.45 GHz ISM band, with a total size of 40×40×0.8 mm 3 .…”

“…While most of them reported patch based linear antennas with switchable beam capabilities, and their operating frequencies spanned GPS to ISM band, all of them provided beam switching in one plane, meaning either the elevation plane or the azimuth plane were scanned at specific angles. Some of them such as [9] depended on complex RF circuitry to accomplish that. None of the previous works provided full 3D switchable beam scanning using simple control.…”

An 8-element planar antenna array with electronically controlled switchable-beam pattern is proposed. The planar antenna array consists of patch elements and operates in the 2.45 GHz ISM band. The array is integrated with a digitally controlled feed network that provides the required phases to generate 8-fixed beams covering most of the upper hemisphere of the array. Unlike typical switchable beam antenna arrays which operate only in one plane, the proposed design is the first to provide full 3D switchable beams with simple control. Only a 3bit digital word is required for the generation of the 8-different beams. The integrated array is designed on a 3-layer PCB on a Taconic substrate (RF60A). The total dimensions of the fabricated array are 187.1 × 261.3 × 1.3 mm 3 .
