Comments on "Wide-band E-shaped patch antennas for wireless communications"

For original paper see Yang, F. et al., ibid., vol.49, p.1094-1100 (2001). The writer disputes the novelty claimed by Yang et al. for the E-shaped patch antenna in wireless communications. He points out that it is a special case of the double C-patch antenna which he invented in 1994 (Sanad, M. Proc. IEEE AP-S Symp., p.2116-19, 1995). He refers to papers and patents which describe the further development of the double C-patch antenna and also its application as the basis of internal integrated antennas for portable wireless communication equipment, including cellular phones.
