Abstract

Using waveguides is inevitable in many applications. They have number of advantages rather than planar guiding structures such as lower
loss, high power handling capability, absence of substrate mode losses and etc. Waveguides manufacturing cost and their size at low microwave
frequencies are the biggest disadvantages. In this paper, an open ended waveguide antenna is loaded with broadside coupled omega shaped
metamaterial, proposed. Because of supporting backward waves, it can radiate below the cutoff frequency of corresponding empty waveguide.
This phenomena can use for miniaturization of them.
