Dual mode triple band patch antenna based on two-dimensional composite right/left-handed transmission lines

摘要

In this paper, a triple band dual mode patch antenna is proposed. Modified mushroom resonators are embedded in the substrate of the conventional patch antenna to induce zeroth and negative order resonances in addition to the existing positive order resonances. The proposed antenna exhibit two patch like modes (n = ±1) and one monopolar mode (n = 0).
