Abstract
An omnidirectional antenna is provided. The omnidirectional antenna includes a waveguide configured to transmit a fed signal, a microstrip line configured to radiate the fed signal transmitted from the waveguide, and a radiation guide configured to guide the signal radiated from the microstrip line to omnidirectionally radiate the signal, wherein a waveguide cavity of the waveguide is bent at least once within the waveguide so that two surfaces of the microstrip line meet perpendicularly to a central axis of the waveguide cavity.
