Case for electronic device
View Patent ↗A case for an electronic device according to the present disclosure meta-groves having different structures and formed symmetrically, asymmetrically, periodically, or non-periodically or meta-patches attached symmetrically, asymmetrically, periodically, or non-periodically at positions where the meta-grooves are formed, thereby improving the performance of antennas. Accordingly, there is an effect that it is possible to usefully use a mobile electronic device including arranged antennas therein even in a 5G environment having a millimeter wave band.
1. An auxiliary case attachable to a main case for housing an electronic device, the auxiliary case comprising:
meta-grooves having different structures and formed symmetrically, asymmetrically, periodically, or non-periodically, at a position facing at least one antenna included in the electronic device when the auxiliary case is attached to the main case, or
meta-patches attached symmetrically, asymmetrically, periodically, or non-periodically, at a position facing the at least one antenna included in the electronic device when the auxiliary case is attached to the main case,
wherein the meta-grooves are formed on the auxiliary case, or the meta-patches are attached to a position corresponding to the meta-grooves.
2. The auxiliary case of claim 1 , wherein the meta-grooves or the meta-patches are formed in bar shapes on a front, a side edge, or a top edge of the auxiliary case.
3. The auxiliary case of claim 1 , wherein the meta-grooves or the meta-patches are formed in circular shapes on a front, a side edge, or a top edge of the auxiliary case.
4. The auxiliary case of claim 1 , wherein the meta-grooves or the meta-patches are formed in circular ring shapes on a front, a side edge, or a top edge of the auxiliary case.
5. The auxiliary case of claim 1 , wherein the meta-grooves or the meta-patches are formed in binary pixel shapes on a front, a side edge, or a top edge of the auxiliary case.
6. The auxiliary case of claim 1 , wherein the meta-grooves or the meta-patches are formed in cross shapes on a front, a side edge, or a top edge of the auxiliary case.
7. The auxiliary case of claim 1 , wherein the meta-patches are formed in at least a partial area of the meta-grooves.
8. A case for an electronic device, the case comprising:
at least one of meta-grooves having different structures and formed symmetrically, asymmetrically, periodically, or non-periodically, or
meta-patches attached symmetrically, asymmetrically, periodically, or non-periodically, at a position facing at least one antenna included in the case for electronic device,
wherein the meta-patches are formed in at least a partial area of the meta-grooves.
