- Abstract
- This letter presents a printed fan-shaped meandered dipole antenna with mutual-coupled dual resonance for enhancing impedance bandwidth in a compact antenna size. The proposed antenna consists of a printed dipole antenna mutually coupled to an antenna parasitic element of a different size for dual resonance and microstrip feeding. By applying a fan-shaped meander-line structure, the proposed antenna occupies a low-profile miniaturized electrical size of 0.21.0 x 0.21.0 x 0.08.0 at 920 MHz. The proposed antenna, which was implemented and fabricated on an FR-4 substrate, achieved a wide 10 dB impedance bandwidth of approximately 12% and a peak gain of 3.2 dBi. Depending on the antenna length at the two resonant frequencies, the impedance bandwidth in the proposed antenna can be controlled.
