Antenna yeLog periodic iantenna inotungamira ine mafrequency akawanda ekushanda. Kusiyana kwayo kuri muhunhu hwayo hwemagetsi, hwakadai se impedance uye ma directional patterns, ayo anodzokorora logarithmically uye nguva nenguva ne frequency.

Hunhu:

1. Hunhu hweBroadband: Iyi ndiyo mukana wayo mukuru. Antena imwe chete yelog periodic inogona kufukidza huwandu hwakakura hwemafrequency (senge 10:1 kana kutopfuura), uye inogona kushanda mumafrequency band akawanda pasina kugadzirisa.
2. Mwaranzi inotungamira: Ine gwara, se "tochi", iyo inoisa simba mudivi rimwe chete kuti ibudise uye inogona kugamuchira zviri nani zviratidzo kubva kudivi iroro, zvichikonzera kuwedzera kukuru uye kugona kwakasimba kwekudzivirira kukanganiswa.
3. Hunhu hwemaumbirwo: Yakaumbwa nematanho esimbi anotenderera ane hurefu hwakasiyana uye nzvimbo dzakasiyana, saizi nenzvimbo yeaya ma "oscillator" zvinotevedzera mitemo yakasimba ye "logarithmic periodic". "Oscillator" refu kwazvo ndiyo inosarudza frequency yakaderera yekushanda, uye "oscillator" pfupi ndiyo inosarudza frequency yepamusoro yekushanda.
4. Nheyo yekushanda: Kune frequency chaiyo, chikamu che "resonant unit" cheantenna ndicho chinofashukira uye chinobatanidzwa mumwaranzi, uye nzvimbo iyi inonzi "effective zone". Kana frequency ikachinja, nzvimbo iyi inoshanda ichafamba-famba ichidzokera shure pachimiro cheantenna.

Mashandisirwo:

1. Kugamuchira TV: Maantenna ekutanga ekugamuchira TV ekunze aiwanzo shandiswa seizvi.
2. Kutarisa nzvimbo dzeredhiyo dziri kumativi ose.
3. Kuyedzwa kwekuenderana kwemagetsi: Kunoshandiswa se antenna inotumira kana kugamuchira mukamuri rine rima yekuyedzwa kwekubuda kwemwaranzi uye kudzivirirwa kwekudzivirira kwemwaranzi.
4. Kutaurirana kwemafungu mapfupi: Inoshandiswa se antenna yekutaurirana inotungamira mubhendi remafungu mapfupi.
5. Kutarisa RF nekutsvaga gwara: Kunoshandiswa pakuongorora nekutarisa masaini pahuwandu hwakakura hwemafrequency.

QualwaveMa antenna e log periodic anofukidza huwandu hwema frequency kusvika ku 6GHz, pamwe chete nema antenna e log periodic akagadzirwa zvinoenderana nezvinodiwa nevatengi.
