Abstract
A slot antenna having stubs is provided, in which a strip transmission line for transmitting a transverse electromagnetic mode (TEM) signal is formed by using a multi-layered substrate, and a plurality of slots are used for the strip transmission line. Thus, an omnidirectional radiation pattern is obtained, and the directivity of the slot antenna is improved.
