Subject(s): Stacked parasitic antenna; Digital Terrestrial Television (DTT)
In this paper a rectangular patch antenna with two slots, integrated with a stacked parasitic antenna, is presented. These techniques allow a bandwidth (BW) and gain enhancement, two of the major limitations of traditional patch antennas. The antenna is designed to operate at 754 MHz for energy harvesting applications, from the Portuguese Digital Terrestrial Television (DTT) signal. The measured antenna BW is 22.5 MHz, representing an enhancement of around 17 MHz in respect to the simulated BW of the corresponding single patch configuration.
