N2 - This paper presents an incident angle ( boldsymbol{ theta}) insensitive metamaterial absorber (MTMA) operating at 2.45 GHz. De-signed MTMA is based on the proposed unit cell (UC) which has a size of 20-by-20 sq. mm. UC is developed on Rogers RO4350B and employs two half-circular rings connected by a line. It is imperative to note that the considered UC geometry showed a high absorption level for varying theta. In particular, the peak absorption of 99.9% is obtained when theta was changed between 0 and 30 deg. Furthermore, the minimum absorption of 80% was achieved at boldsymbol{ theta=70} deg. Finally, the results reveal that developed MTMA can be utilized in practical scenarios, e.g.,
