	Dalam komunikasi radio, antena omnidirectional adalah kelas antena yang memancarkan daya radio yang sama ke segala arah tegak lurus terhadap sumbu (arah azimut), dengan daya bervariasi dengan sudut sumbu (sudut elevasi), menurun ke nol pada sumbu. Ketika digambarkan dalam tiga dimensi (lihat grafik) pola radiasi ini sering digambarkan berbentuk donat. Perhatikan bahwa ini berbeda dari antena isotropik, yang memancarkan daya yang sama ke segala arah, memiliki pola radiasi bola. Antena omnidirectional yang berorientasi vertikal banyak digunakan untuk antena nondirectional di permukaan bumi karena memancar secara merata ke semua arah horizontal, sedangkan daya yang dipancarkan turun dengan sudut elevasi sehingga sedikit energi radio yang diarahkan ke langit atau turun ke bumi dan terbuang sia-sia. . Antena omnidirectional banyak digunakan untuk antena penyiaran radio, dan pada perangkat seluler yang menggunakan radio seperti ponsel, radio FM, walkie-talkie, jaringan komputer nirkabel, telepon nirkabel, GPS, serta untuk stasiun pangkalan yang berkomunikasi dengan radio seluler, seperti polisi dan operator taksi dan komunikasi pesawat.

High-gain omnidirectional antennas are generally realized using collinear dipole arrays.

Antena omnidirectional gain tinggi umumnya direalisasikan menggunakan array dipol collinear.

In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.[1][2] When graphed in three dimensions (see graph) this radiation pattern is often described as doughnut-shaped. Note that this is different from an isotropic antenna, which radiates equal power in all directions, having a spherical radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.
