The proposed antenna operates at around 10 GHz and 12.5 GHz. Making uses of the first two fundamental modes of waveguide cavity, i.e., TE101 and TE102, we can realize a monopole-like radiation pattern for the lower band and a broadside radiation pattern for the higher band. The proposed antenna is very suitable to be used in the communication systems where both satellite and terrestrial links are needed.Dual band | Dual mode | Monopole | Substrate integrated waveguideconference paper2-s2.0-84949113808https://api.elsevier.com/content/abstract/scopus_id/84949113808
