Abstract
This paper presents a novel low-profile miniaturized dipole antenna with omnidirectional radiation. The structure (60mm × 60mm × 4mm) is made up of a dipole antenna with branches attached. For the geometry of the antenna, it looks like a flywheel which is constructed by using four branches conflguration on metallic ground. In this work, this proposed antenna can be divided into four parts: 1) a metallic patch printed on the top of the FR4 substrate with εr = 4.4 and the thickness of 1.0 mm; 2) a dual-substrate connected by four copper branches; 3) a coax feed connected to the center of bottom substrate, and 4) a radome located above the antenna. The simulation results show that the bandwidth is 2.33 ~2.38 GHz and the resonance frequency is 2.35 GHz. Moreover, the radiation characteristic of the designing antenna shows a good omnidirectional performance.
