摘要：
Quad-band slow-wave (SW) printed inverted-F antennas (IFA) for 0.9 GHz, 1.57 GHz, 1.8 GHz, and 2.45 GHz are proposed. Multi-band behavior is achieved by combining L-loaded printed-IFA and two printed radiators. Each of the four radiators has a small effect on the performance of the other radiators. Compact printed-IFA antennas are realized using SW structures such as saw-tooth, meander lines, first fractal iteration and high impedance wire (HIW). A size reduction of 40% is achieved. The proposed antennas maintain the same far-field radiation patterns of the conventional printed-IFA. They also possess the properties of good performance, compact size, low profile, and low cost. Hence, they are suitable for implementation in wireless applications.
