In this paper, a new wire inverted-F antenna (IFA) is proposed, which is structured by grids of thin wires. This novel wire grid IFA is ~0.3λ long and ~0.14λ high and renders 41% fractional bandwidth which is nearly 5 times higher than the bandwidth of a classic IFA. In addition to the novel structure and high bandwidth, the distinguishing feature of the design process employed is its computational efficiency. While the constituent wires of the wire grid (WG) model are one-dimensional (1D) thin wires, they can indirectly form very thick arms leading to bandwidth enhancement. The thin-wire structure of the WG-IFA provides the opportunity to carry out the analysis and design accurately and fast in a 1D MoM-based software like NEC.
