In this paper, a low-profile dual-band stacked microstrip monopolar patch antenna is proposed. By utilizing a stacked-patch configuration, a dual-band property is achieved. A coupled annular ring and a set of conductive vias are loaded into the antenna structure to widen the impedance bandwidth. In order to verify the performance of the proposed antenna, a fully functional prototype was fabricated and measured. The measured results demonstrate that the antenna can achieve impedance bandwidths from 2.24 to 2.53 GHz in the low band and from 5.42 to 5.98 GHz in the high band, separately. Within the operating frequency, omnidirectional radiation patterns are also observed. Besides, the proposed antenna possesses a low-profile structure with a height of 4.175 mm or 0.057λ₀ (where λ₀ is the free-space wavelength of 4.1 GHz), which can be easily hidden on the top of a vehicle. With these merits, the proposed design is very appropriate for wireless local area network (2.4-2.48 GHz and 5.75-5.825 GHz) and car-to-car (5.85-5.925 GHz) communications.
