“…The components used in previous studies provide a discrete sweep in frequency. To obtain continuous variation, the varactor diode can be used in a reconfigurable antenna [15][16][17][18][19]. By controlling the DC bias voltage, the capacitance of the varactor could be changed.…”

This article presents a reconfigurable antenna using digitally tuneable capacitors (DTCs). Mounted on a 120 × 200 mm2 ground plane, the radiating element has very compact dimensions of 0.06λg × 0.016λg × 0.0016λg (with λg being the wavelength at 585 MHz). The proposed structure could be operated in the white-space frequency band from 470 to 700 MHz. The antenna system is composed of two radiated elements that are placed at the corner of the board. The active components were soldered onto the antennas and controlled by an embedded microcontroller via the I2C interface. Antenna impedances were simulated and evaluated by measurement with an impedance-matching bandwidth of 39.32% (470–700 MHz) for an S11 less than −6 dB. Furthermore, the numerical results show a realized maximal gain ranging from −2.2 dBi at 470 MHz to 1.87 dBi at 700 MHz. Lastly, the diversity gains based on the radiation pattern of two resonators were calculated. The results show envelope correlation coefficient (ECC) values lower than 0.5 for the different configurations.

“…This real‐time communication can effectively reduce the driving risk by providing warnings such as intersection collision, overtaking collision, head‐on collision, and rear‐end collision. To support such a diverse nature of communication in ITS, a multiband, wideband, and reconfigurable RF front‐end is needed …”

“…To support such a diverse nature of communication in ITS, a multiband, wideband, and reconfigurable RF front-end is needed. 2 The RF front-end (the antennas in particular) are also demanded to have high isolation between the Tx and Rx channels, high-frequency selectivity, and good out-of-band rejection performance to avoid the potential interferences. This article focuses on the RF front-end particularly antenna design for the vehicleto-infrastructure scenario.…”

This article presents a novel reconfigurable aperture coupled fed antenna with a defected ground plane for an intelligent transportation system (ITS). The antenna design with aperture coupled feed line. The defected ground plane allows variation in reactance of the proposed antenna around the center frequency and coupling of energy. This antenna is multiband and works at resonant frequencies of 2.45, 5.9, and 24 GHz allowing measurable reconfigurability with the help of PIN diode. From the measurement, one can infer that the bandwidth is 0.8, 1, and 8.5 GHz, and gain obtained are 11.7, 4.04, and 4.4 dBi at 2.45, 5.9, and 24 GHz frequencies, respectively. It is circularly polarized with a broadside radiation pattern. The advantage of this design is that it covers all the three bands allocated by the Federal Communications Commission for ITS and vehicular communication applications. It is an electrically small, low profile antenna and has a simple structure thus gives large bandwidth.
