Compact and low-profile conical antenna for automotive DSRC application

A novel fully textile-integrated antenna based on a slotted short-circuited microstrip line has been designed, manufactured and experimentally validated for its use in automobile upholsteries for dedicated short-range communications. The antenna can be manufactured using an industrial loom and a laser prototyping machine, avoiding subsequent treatments, sewing procedures or coatings. The manufactured antenna presents a central working frequency of 5.9 GHz and a 9.3% bandwith. Good agreement between simulations and measurements has been achieved.

“…At present, a lot of research works focus on antennas applied to DSRC and C-V2X, and generally wide beam array are employed to ensure the stability of vehicle-ground communication. In [2], a new conical monopole antenna with omnidirectional radiation in the horizontal plane is proposed. In [3], a circularly polarized antenna at 5.8GHz with beamwidth of 236° and 298° in plane E and plane H is proposed.…”

With the rapidly development of intelligent connected vehicle, Security problem is becoming a core concern of vehicle owners. Current vehicle-ground communication related researches mainly focus on wide-beam antenna, which may result in data leakage for its wide signal coverage of on-board terminal. In this paper, a novel kind of beam scanning array which can be used for security enhancement of intelligent connected vehicles is proposed. This new kind of array is composed of a beam controller which based on the Butler matrix and a four-cell patch, which can not only reduce the power consumption of on-board terminal but also can enhance the security performance of V2X DATA link. This new array is characterized with lightweight, low profile, and low cost. Good performance of the on-board array can be observed in the simulation results.

“…The idea of combining the radiation of multiple antennas to obtain specific pattern shape dates back to the beginning of the 19th century, when the history of wireless communications began [1,2]. Nowadays, antenna arrays are widely used in a large variety of scenarios involving far-and near-field focusing/multifocusing applications for satellite, cellular, vehicular, and sensor networks [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. However, even if the array technology is already widespread, its importance is expected to further increase, since the directionality of the communications will represent a basic enabling functionality of the forthcoming fifth-generation (5G) and Internet of things (IoT) systems [18][19][20][21].…”

One of the main targets of the forthcoming fifth-generation (5G) cellular network will be the support of the communications for billions of sensors and actuators, so as to finally realize the Internet of things (IoT) paradigm. This pervasive scenario unavoidably requires the design of cheap antenna systems with beamforming capabilities for compensating the strong attenuations that characterize the millimeter-wave (mmWave) channel. To address this issue, this paper proposes an iterative algorithm for sparse antenna arrays that enables to derive the number of elements, their amplitudes, phases, and positions in the presence of constraints on the far-field pattern. The algorithm, which relies on the compressive sensing approach, is formulated by transforming the original nonconvex optimization problem into a convex one. To prove the suitability of the conceived solution for 5G IoT mmWave applications, numerical examples and comparisons with other existing methods are provided, considering synthesis problems with different pattern and aperture specifications.
