T -shaped Broadband CPW  fed folded-Slot Antenna for 
5.8 GHz RFID Applications



Uvod vsebuje stvari, ki ne opisujejo antene.
Slaba kakovost fotografije Fig.2.
Ucinek tokov na zunanji strani plasca napajalnega kabla ni opisan.
Antena ne bo zdrala 100W moci.
Antena je zelo velika glede valovno dolzino.
Ucinkovitost >95% je na FR4 vprasljiva?
Koordinatni sistem niti polarizacija na Fig.8 nista navedena.
Smerni diagram na Fig.8 ne utemeljuje dobitka na Fig.9.


The introduction includes matters not related to the antenna design.
The quality of Fig.2 is not acceptable for publication.
The effects of currents on the outer side of the feeding coax is not investigated.
The proposed antenna will not survive 100W of incident power on a lossy FR4 substrate.
The proposed antenna is quite large compared to the wavelength and to the narrowband specs.
A radiation efficiency >95% on a lossy FR4 substrate is questionable.
No coordinate system nor polarization direction is indicated on Fig.8.
The radiation pattern on Fig.8 does not justify the gain on Fig.9.
