    "abstract": "We consider resonant patch antennas, implemented using loaded\ntransmission-line networks and other exotic structures having engineered\ndispersion. An analytical expression is derived for the ratio of radiation\nquality factors of such antennas and conventional patch antennas loaded with\n(reference) dielectrics. In the ideal case this ratio depends only on the\npropagation constant and wave impedance of the structure under test, and it can\nbe conveniently used to study what kind of dispersion leads to improved\nimpedance bandwidth. We illustrate the effect of dispersion by implementing a\nresonant patch antenna using a periodic network of LC elements. The analytical\nresults predicting enhanced impedance bandwidth compared to the reference\nresults are validated using a commercial circuit simulator. Discussion is\nconducted on the practical limitations for the use of the proposed expression.",
