| Moetapele-mw | Kenyelletso ea Ultra Wideband Omnidirectional Antenna |
E hlahisa moetapele oa microwave tech.,(moetapele-mw)lenaka le lecha la ultra-wideband omnidirectional ANT0104. Antenna ena e matla e etselitsoe ho sebetsa maemong a mangata ho tloha ho 20MHz ho isa ho 3000MHz, e etsa hore e tšoanelehe bakeng sa lits'ebetso tse fapaneng ho kenyeletsoa likhokahano tse se nang mohala, litsamaiso tsa radar le tse ling.
Phaello e kholo ea antenna ena e kholo ho feta 0dB, 'me phapang e kholo ea ho pota-pota ke ± 1.5dB, ho netefatsa hore phetisetso ea matšoao e tšepahalang le e tsitsitseng. Ts'ebetso ea eona e matlafatsoa le ho feta ke mokhoa oa mahlaseli a ± 1.0dB o otlolohileng, o fana ka tšireletso e ntle ka hohle.
ANT0104 e na le litšobotsi tse otlolohileng tsa polarization, e etsang hore e be e loketseng lits'ebetso moo phetisetso e otlolohileng e ratoang. Ntle le moo, antenna's VSWR ≤2.5:1 le 50 ohm impedance e fana ka mokhoa o nepahetseng oa ho tsamaisana le tahlehelo e nyane ea lets'oao.

Bakeng sa tekanyo e sebetsang ea coefficient ea antenna directivity, re e hlalosa ho tloha ho boholo ba mahlaseli a mahlaseli a antenna.
Directivity D ke karo-karolelano ea boholo ba matla a mahlaseli a mahlaseli a P(θ,φ) Max ho boleng ba eona bo bolelang P(θ,φ)av sebakeng sa sebaka se hōle, 'me ke tekanyo e se nang tekanyo e kholo ho feta kapa e lekanang le 1. . Foromo ea lipalo e tjena:
Ntle le moo, directivity D e ka baloa ka foromo e latelang:
