Abstract

In this paper, we have presented the design of a compact Epsilon negative (ENG) zeroth order resonating (ZOR) antenna based on conventional mushroom type (CMT) of structure with complementary split ring resonator (CSRR). In the proposed antenna, unit cell is constructed by etching the CSRR on the patch of CMT structure. The 4 unit cells antenna is excited with quarter wavelength transmission line (TL). The size of the unit cell is 0.073 λ₀ × 0.073 λ₀ and the physical size of antenna is 0.073λ₀ ×0.29λ₀ at ZOR frequency, where λ₀ is the free space wavelength. The radiation efficiency and absolute gain are observed to be 34.6 % and -2.67 dB respectively.
