Abstract: The article presents a very compact dual band microstrip patch antenna for Long Term Evolution (1.7-1.8 GHz) and Radio Frequency Identification (2.45 GHz) applications. The proposed antenna has been designed using Fire Resistant FR4 Epoxy substrate. The patch antenna dimensions are 44.2 x 25.8 x 1.6 mm and have a 50 ohm Microstrip Line feed. The antenna has a low return loss of about -23.2 dB with VSWR of almost 1.14 and a good directivity of 2.52 dBi at 1.82 GHz and it has return loss of -32.13 dB, VSWR of 1.05 and directivity of 4.36 dBi at 2.459 GHz. The proposed antenna operates between 1.65-1.86 GHz and 2.38-2.54 GHz with resonating frequencies 1.82 GHz and 2.46 GHz. The performance of the proposed antenna is analyzed using CST Microwave Studio software.
