log periodic antenna 7 dBi Ụdị. Nweta, 0.5-2 GHz Frequency Range RM-LPA052-7

antenna log-periodic bụ antenna brọdband pụrụ iche nke arụmọrụ eletrik ya, dị ka impedance na usoro radieshon, na-emegharị ugboro ugboro na logarithm nke ugboro. Ọdịdị ya kpochapụwo nwere usoro ihe dị iche iche dipole ọla dị ogologo, nke 交叉 jikọtara ya na eriri nri, na-eme usoro geometric na-echetara ọkpụkpụ azụ.

Ụkpụrụ ọrụ ya na-adabere na echiche "mpaghara na-arụ ọrụ". N'otu oge na-arụ ọrụ kpọmkwem, ọ bụ naanị otu ihe ndị nwere ogologo dị nso na ọkara wavelength na-enwe obi ụtọ ma na-ahụ maka radieshon mbụ. Ka ọ na-agbanwe ugboro ugboro, mpaghara a na-arụ ọrụ na-aga n'ihu n'usoro antenna, na-eme ka arụmọrụ obosara ya dị.

Isi uru nke antenna a bụ bandwit ya sara mbara, na-erute 10: 1 ma ọ bụ karịa, yana arụmọrụ kwụsiri ike n'ofe band. Ihe ndọghachi azụ ya bụ usoro dị mgbagwoju anya na uru na-agafeghị oke. A na-eji ya n'ọtụtụ ebe na nnabata telivishọn, nleba anya ụdịdị dị iche iche, Nnwale Electromagnetic Compatibility (EMC), yana usoro nkwukọrịta chọrọ ọrụ sara mbara.
