Dimension and gain comparison between UHF RFID reader antennas.

Antenna name	Picture	Dimension	Peak gain
Proposed ellipse shaped antenna		100 mm × 80 mm × 1.6 mm	6.5 dBi
[1]		101.5 mm × 220 mm × 32.6 mm	6.6 dBic
[3]		882 mm × 80 mm × 1.5 mm	−16.1 dBi (simulated)
[5]		50 mm × 50 mm × 0.5 mm	0.06 dBic
[7]		250 mm × 250 mm × 36 mm	7.3 dBi
[8] (for this dual band antenna only the UHF band is considered for comparison)		108 mm × 108 mm × 1.6 mm	3.5 dBi
