Abstract
A broadband probe-fed stacked patch antenna is presented in this paper. The probe is composed of two printed feed-lines and three vias. The feed-lines help of compensating the inductances produced by the vias. Further, with the stacked patch method, the bandwidth of the antenna is enhanced. The simulated results show the antenna has a bandwidth over 40% (VSWR<2) and good radiation performance.
Highlights
With the increase of the application of microstrip patch antenna, its bandwidth enhancement has been one of the most attractive research fields
In the conventional edge- and probe-fed patch antennas, the method is greatly restricted because of the increasing spurious radiation of the feed-lines and the increasing inductance of the probe resulting from the thick substrate
A wideband staked patch antenna fed by a printed meandering probe has been designed in this paper
