Design of “T” Shaped Slotted Microstrip Antenna with Truncated Corners for WLAN/C Band/X Band Applications

To cater the applications in WLAN/C/X bands, a slotted microstrip antenna operating in 5.10 - 13.84 GHz is projected in this paper. The recommended antenna resonates at 5.6 GHz (at -38.13 dB), 7.6 GHz (at -38.22 dB) and 11.18 GHz (at - 28.06 dB). The proposed radiator is manufactured on FR4 with measured size of 40 x 40 x 1.6 mm<sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">3</sup>. “T” shaped slot on top side of the FR4 substrate and on the bottom side, there is a partly ground structure. Using HFSS simulation, the dimensions of all parameters were tuned to achieve the target frequency range of 5.10 GHz to 13.84 GHz.
