“…Recently, the design of miniaturized fractal antennas capable of providing multiple resonant frequencies has received much attention due to ease of installation on vehicles and aerodynamic compatibility [5]. Several research papers have proposed novel antenna design techniques based on fractal geometry [6][7][8], showing how proper selection of fractal geometry can help reduce the overall antenna size and, simultaneously, ensure multi-band operation.…”

Abstract-The present paper analyses and documents the merits of incorporating fractal design in microstrip antenna intended to be mounted on and integrated into the design of smart vehicles. A novel design is proposed for a compact tri-band hexagonal microstrip antenna to be integrated with the body of a smart vehicle for short range communication purpose in an Intelligent Transport System (ITS). This antenna can be used at 1.575 GHz of GPS L1 band for vehicle to roadside communication, at 3.71 GHz of mobile WiMAX band (IEEE 802.16e-2005) for blind spot detection and at 5.9 GHz of DSRC band (IEEE 802.11p) for vehicle to vehicle communication. At 3.71 GHz, the two major lobes of the antenna radiation beam, tilted by 35 • on both sides from its broadside direction, help the vehicle to detect blind spots efficiently. The largest dimension of the proposed antenna corresponds to the lowest resonating frequency, 1.575 GHz. Compared to the conventional hexagonal patch, the modified Sierpinski fractal proposed herein reduces the overall area, at 1.575 GHz, by 75%, with 5.2 dBi gain. In comparison with other popular fractals, the proposed fractal structure achieves demonstrably better antenna miniaturization. When the antenna is mounted on the vehicle, considered an electromagnetically larger object, the simulated and on-vehicle experimental results show antenna gains of more than 5.5 dBi at 1.575 GHz, 8 dBi at 3.71 GHz and 9 dBi at 5.9 GHz in the desired direction with negligible amount of electromagnetic interference inside the car.

“…Recent research on multi-functional vehicle antennas has focused on both small and unobtrusive structures with minimum sacrifice in performance within each service band. Variations of frequency-independent spiral structures [1], printed inverted-F antennas [2], and dual-polarized antennas [3] have been developed for multifunctional vehicle antennas. In addition, handset antenna design techniques such as switch-controlled reconfigurable geometry [4] and parasitic-driven multiband structures [5] can be adopted to satisfy compact size and multiband operation for automotive application.…”

Abstract:A new multi-functional vehicle antenna, consisting of LNA-integrated non-uniform helical antenna for both FM and terrestrial digital multimedia broadcasting (TDMB) operation, and a monopole antenna for the PCS operation is proposed. The proposed architecture combines the three antennas in such a way as to maximum the reuse of the antenna structure and, thereby, reduces the overall antenna size. To realize a single-port excitation of three different band antennas, the PCS antenna and FM antenna is simultaneously excited with the help of steel stud while the TDMB antenna is magnetically coupled from a portion of the FM antenna body. Keywords: LNA-integrated antennas, magnetically coupled antennas Classification: Microwave and millimeter wave devices, circuits, and systems References

“…Similarly for mobile communication applications a pin-patch antenna would need to provide a dual-band performance in the 900 and 1800 /2000 MHz bands. Low-profile dual-band antenna solutions based upon modified PIFAs have been demonstrated for roof-mount automotive cellular applications [8], but these suffer from pattern asymmetry. In this letter we describe how the basic pin-patch antenna can be modified to provide operation in two bands with spacings of ~2:1 to meet these dual-band requirements and maintain the desired omni-directional azimuth pattern.…”
