A miniaturized printed rhombus slot antenna with a protruded ground plane has been demonstrated. The proposed antenna has its dimensions of 37.4 mm x 54 mm which is suitable for the WiMAX operations. Experimental results show that the impedance bandwidth of a printed slot antenna can be significantly improved by the use of an offset microstrip feed line. And the antenna size can be reduced about 47%...
This paper presents a novel printed monopole antenna with band-notched characteristics. The proposed antenna consists of a sector radiating monopole and a microstrip feedline connected in shunt a quarter wavelength open-circuited stub. In order to achieve band-notched performance, using a single open-circuited transmission line (a stub) of length quarter wavelength, connected in parallel with the...
