In this article, a broadband beam scanning antenna array is proposed in Q-band attributed to miniaturized size, wideband and high integration. A patch antenna element is utilized with a back cavity, which is formed by metallic via holes and ground plane. A 1 × 4 series fed sub-array is implemented by the patch element using multilayer PCB. Four symmetrical sub-arrays and Butler matrix feeding network are used to form the antenna array with high gain and decrease side lobes. The Butler matrix is implemented by substrate integrated coaxial line, which provides low loss of around 0.09 dB/mm from 40 to 50 GHz. The measured antenna array bandwidth is 9.8 GHz (21.8%) under the condition of voltage standing wave ratio less than 2. The main beam of the antenna array in azimuth direction is tilted to −28.5 , −14.1 , 18.4 and 35.6 and the gains are 13.11, 13.88, 14.02 and 11.78 dBi at 45 GHz, respectively. Both the measured and simulated results agree well.

“…In [9] and [10], a coaxial to SICL transition has been reported. A novel rectangular waveguide to SICL transition is proposed in [11] to act as a four way power divider to feed a circularly polarized antenna array in E-band. One of the most popular transition currently used in SICL technology is the coplanar waveguide (CPW) transition [12], [13] in which a plated via connects the central conductor of SICL to signal line of CPW.…”

In this communication, the design and working principle of a wideband microstrip to substrate integrated coaxial line (SICL) planar transition for millimeter-wave applications is presented. In the proposed work, along with tapering of microstrip line, two triangular slots in the top ground plane are utilised to compensate for the discontinuity arising at the microstrip-SICL junction & minimize reflections over a wide bandwidth. To confirm the theoretical claims, the proposed microstrip to SICL transition is fabricated using standard multilayer PCB process. The measured results of the prototype indicate return loss better than 14 dB with a maximum insertion loss of 1.78 dB for DC to 40 GHz band (19 dB bandwidth up to 20 GHz with insertion loss less than 0.71 dB). The modeling of proposed transition is presented & versatility of the design is illustrated for different dielectric constant & thickness. Effortless integration of SICL with the widely used microstrip transmission line simplifies the feeding process of SICL based broadband antennas & microwave circuits. INDEX TERMS Millimeter-wave, planar, substrate integrated coaxial line (SICL), wideband transition.

“…More useful antennas such as the circularly polarised antennas of [16][17][18] working in the millimetre wave band will have applications in 5G systems especially if they can also steer their beams. For example, the leaky-wave antenna by Rahmani and Deslandes [16] operates in 22-28 GHz band with gain values up to 10 dBi along with the capability of having a wide (84°) scanning range.…”

“…This has a Vivaldi based structure and is capable of scanning its beam in 3D due to its distributed organisation of array elements. The circularly polarised antenna by Cheng et al [18] targets a higher millimetre-wave band in the range 71-78 GHz with a maximum peak gain of 12.3 dBi. This antenna however employs a complex substrate integrated coaxial line feeding network with a waveguide-to-SICL transition.…”

This study presents a 5G antenna array for millimetre‐wave communications. Overall size of the proposed antenna array is 40 × 15 mm2, and operates in a measured 23.76–42.15 GHz frequency range. A planar four‐way feed network has been designed, optimised and used to excite the antenna array elements. The single element of the array is spiral monopole surrounded by a boundary of vias with extended ground plane in an inverted U‐shaped manner. Hexagonal parasitic patches have been introduced at the backside to enhance impedance performance of the antenna element. Peak gain of the proposed antenna array is 11.5 dBi with radiation efficiency more than 83% in its entire operating band. The antenna gives a narrow beam‐width of as low as 10.1°. Single element and its 1 × 4 array have been fabricated using standard printed circuit board (PCB) process. Measured results show excellent compliance with the simulated design objectives. The antenna is low cost, low profile with simple design and is capable of being deployed in future 5G communication mobile networks.
