“…Table 1 provides the performance comparison between the proposed antenna and other LTE antennas for automotive mobile communications. Comparison to other antennas in References 9,11‐13, the proposed antenna with a compact volume can cover the 698 to 960 and 1710 to 2690 MHz bands simultaneously. It is worth noting that the proposed compact LTE antenna is realized without additional matching network, which degrades the radiation efficiency.…”

“…However, the height of this antenna is 73 mm, which cannot meet the EU specification of 60 mm 8 . Although the antennas in References 12 and 13 can create two widebands to cover 698 to 960 and 1710 to 2690 MHz, they occupy large space which is difficult to place more antennas in the shark‐fin plastic shell. An integrated shark‐fin antenna consisting of four antennas is proposed in Reference 14.…”

This letter presents a compact long‐term evolution antenna, which is capable of covering 698 to 960 MHz and 1710 to 2690 MHz bands simultaneously for automotive mobile communications. Taking performance and aesthetic appeal into account, the antenna is placed in a shark fin plastic shell, which is mounted on the roof of the vehicle. The proposed antenna is mainly composed of a feeding monopole, a grounded strip, a parasitic strip, and a parasitic patch. The lower band is covered by the quarter‐wavelength resonant modes of the feeding monopole and grounded strip. The higher band is originally generated by the high order modes of the feeding monopole and grounded strip, and further widened by the quarter wavelength resonant modes of two parasitic structures. The utilization of some miniaturization techniques, such as parasitic radiating elements, loading substrate, and meandering radiating elements, enables the proposed antenna to achieve a compact structure. Therefore, the proposed antenna only occupies a compact volume of 29 mm × 15 mm × 57 mm. It is worth noting that the proposed antenna achieves two widebands without additional matching network. Besides, the proposed antenna has omnidirectional radiation patterns in the azimuthal plane for the working bands.

This paper designs a vertically polarized, horizontal, omnidirectional vehicle antenna for the mobile communication band, covering the available frequency bands of the wireless sensor network and 5G. The antenna is composed of semi-T monopole and semicone monopole, which are placed vertically on the metal plate, especially suitable for being mounted on top of a car. T-branch mainly works at low frequency, and cone branch mainly works at high frequency. The cone branch adopts tapered structure in order to improve the impedance matching of antenna and increase the bandwidth of antenna. The antenna can be miniaturized by cutting the antenna in half. The operating frequencies of the antenna are 770 MHz–1000 MHz and 1.7 GHz–3.78 GHz which can cover multiple wireless system bands, including GSM, LTE, and 5G.

“…In order to address this problem, 3D solutions have been presented in the LTE700 band [5], [6]. These solutions, however, introduce an upper transverse metallic path that prevents the antenna to fit within the shark-fin shape.…”
