A dual-band monopole antenna exploiting the use of a novel doublenegative metamaterial is discussed in this article for use in vehicular communications. The proposed unit cell consists of an H-cell resonator sandwiched between two inverted "E" shaped resonator connected to a "T" stub. The proposed unit cell exhibits double negative property from 3.4 to 5 GHz.The dual-band property is achieved by loading the monopole with the proposed metamaterial. The loaded monopole antenna offers dual-band property with resonance at 2.4 and 3.8 GHz making the antenna suitable for terrestrial communications in automobiles. Along with dual-band property, the proposed antenna also offers miniaturization through frequency reduction. The prototype antenna is fabricated and the simulation results are validated using experimental measurements. The proposed antenna offers 6% and 9.15% measured impedance bandwidth with voltage standing wave ratio less than 2 and realized antenna gain greater than 3.2 dBi. Furthermore, the impact of the vehicle's body on the antenna performance is simulated and the results are presented.

“…For all these structures, the maximum achievable gain is of the order of 2-6 dB in the UHF and SHF bands, which is not suitable for RFID application because the antenna, which has low performance in terms of gain and directivity, may cause tag detection errors or losses in the supply network in other applications, thus limiting the range of applications. There are numerous techniques based on metamaterials that can be employed above [28], or inside the radiating element [29][30][31]. However, only a single band has been successfully achieved around 2.4 GHz, with a maximum gain of 6 dB, at the expense of increased size.…”

In this research work, the design of a dipole antenna based on metamaterials is proposed, which can be used as a high gain multiband communication device for RFID applications. This antenna is printed on two sides of an Arlon substrate, which has an overall electrical dimension of 0.39 λ0×0.11 λ0×0.0014 λ0. The metamaterials are used to obtain a multiband antenna, and their integration technique into the antenna results in a high gain compared to a conventional antenna without any magnification or additional layer. The simulated and measured results show that the proposed antenna can operate at 0.88-0.97 GHz, 2.41-2.48 GHz, and 5.77-5.91 GHz with a reflection coefficient of less than −10 dB, which make it well suited for RFID at 860-960 MHz and 2.4 GHz/5.8 GHz. All these resonant frequencies show better impedance matching with high gain. The proposed antenna has the advantages of simple design, low profile, easy feeding, low manufacturing cost, and easy integration into the electronic circuit.

A low profile electrically controlled pattern reconfigurable antenna with wide bandwidth is proposed in this article. The antenna is designed on two closely stacked substrates with a very low profile of 0.04λ0. On the top layer of the design is a periodic metasurface and two parasitic strips, and on the bottom layer is a metallic ground etched with rectangle slot. The feed line is designed on the middle layer to excite the metasurface patch antenna. Eight pin diodes are mounted between the parasitic metallic strips and the adjacent metallic metasurface patch cells for pattern reconfiguration. Two DC biasing voltages are employed to control the pin diodes. By changing the DC voltages, antenna can work at three different modes, and the main beam could be steered among 0°, +25°, and −25° directions. The prototype of the antenna is fabricated and the performance of the prototype is measured. The measured S parameters and radiation pattern show good agreement with the simulated results. The measured overlapped impedance matching bandwidth of the proposed antenna at all working modes is 18.3%. The proposed antenna has the advantages of low profile, high gain, wideband and adjustable main beam.
