In this paper new epsilon-zero resonance (EZR)antennas using epsilon negative (ENG) transmission line (TL) are presented. In the proposed antennas, the unit cell of the ENG TL is implemented using a modified mushroom-like structure in which the via hole is placed at the patch edge. This configuration leads to a broadside radiation pattern and also results in the unit cell size reduction. A one unit cell compact size antenna and a nine unit cell high gain antenna using this new configuration are designed and fabricated. Measurement results including radiation pattern, maximum gain and return loss show good agreement with simulation results.
