2.4/5.2 GHz Dual-WLAN Unequal-Arms Dipole Antenna with a Chip Inductor for omni-directional radiation patterns

This paper presents a dual-band unequal-arms dipole antenna. The proposed antenna applied a chip inductor to prevent the inverted current from occurring and has dual-band omni-directional radiation patterns on H-plane. Results show the proposed antenna operates at 2.4 and 5.2 GHz WLAN bands, and the gain level at lower and higher bands are 2.5 and 3.5 dBi, respectively.
