A new gridded parasitic patch stacked microstrip antenna for enhanced wide bandwidth in 60 GHz Band

In this paper is describe a concept of modification design of gridded parasitic patch stacked microstrip antenna for produce wideband characteristic and high gain which is could operate in around 60 GHz band. The modified antenna has combination of feeding microstrip line with multi tuning stubs, two narrow slots and shorting pin. The antenna is use substrate of taconic TLY with thickness of 0.127 mm and Arlon CuClad with thickness of 0.0762 mm. From the modified antenna can produce bandwidth of 15.6 Ghz around 60 GHz as operate frequency in frequency range around from 49.6 to 65.2 GHz. The antenna gain can reach up to 8.4 dBi at 60Ghz with VSWR of 1.06 and directional radiation pattern. The antenna design will promise for millimeter wave application of mobile communication devices such as 5G and 6G standard.
