Slot Antenna | Duality Example Slot antennas are used typically at frequencies between 300 MHz and 24 GHz. The slot antenna is popular because they can be cut out of whatever surfaceThe dual antenna is similar to a dipole antenna. The voltage source is applied at the center of the dipole, so that the voltage source is rotated. Slot dipole antenna with single- and dual-band tuning… Most of the antennas reported in the literature only operate in single-band or dual-band mode. For example, the substrate-integrated wave-guide cavity-backed active slot antenna oscillatorThis Letter pre-sents a slot dipole antenna. The antenna can provide single-band anddual-band operations.
