2 Iteratioal Joural of Iovative Reearch i Sciece, Egieerig ad Techology I thi paper we itroduce the ew modified triagular ierpiki gaket fractal atea method of mometum (MOM) uig iterated fuctio ytem (IFS) geometrical propertie [2] with modificatio. I thi propoed modified triagular lotted ierpiki for igle bad operatio. The propoed atea cover the RFID,WLAN ISM bad ( GHz) bad with -18 db retur lo.the deig ad imulatio wa performed uig method of mometum (MOM) imulatio oftware.thi paper alo decribe deig ad imulated performace of the propoed atea. II. ANTENNA CONFIGURATION The propoed ierpiki atea geometry how i fig.3. A ierpiki fractal patch i prited o the oe ide of the ubtrate ad groud plae i prited o the other ide of ubtrate with 30mil thicke ad the dielectric cotat ε r =3.38. The microtrip fed i ued for the ierpiki fractal patch which fed out edge of the rectagular patch. Microtrip fed lie have 50 Ω impedace ca be ued to excite ierpiki fractal patch how i fig.2. It ha the vertex agle A ad Reoat frequecy cotrolled by the each iteratio. The propoed ierpiki fractal atea prited o the Roger Ro4003 dielectric ubtrate (ε r =3.38 ad 30 mil). Thi ca be calculated by uig formula give by f [ co x x ] c..(1) The atea matched at frequecie calculate approximately for fractal atea give below f r co 2 r c..(2) The iterated fuctio ca be repreet by, w( x, y) ( ax by e, cx dy f ) (3) Where, a,b,c,d,e ad f are real umber Thu our calig factor ca calculate approximately by log p log 3 d log log 2.(4) Copyright to IJIRSET

RESULTS Simulated retur lo of the propoed atea how i fig.4 for ε r =3.38 ad h=30 mil L*W i 25 * 25.I thi geometry propoed ew modified triagular lotted ierki gaket fractal atea reduce the thicke of the atea compare to other ierki gaket fractal atea which i 30 mil ad icreae the badwidth. The retur lo of the propoed atea i -18dB at 2.42GHz.The imulated reoat frequecy reoate aroud GHz. Badwidth of the propoed atea i uitable for the WLAN, RFID atea commuicatio. The reoat frequecy of the atea i how i fig 1. Simulated frequecy good agreemet with the frequecy bad of WLAN,RFID ISM bad which i 2.45GHz ad imulated by the ADS MOM techology. Microtrip lie feed i excite the triagular lotted atea, The imulated impedace badwidth for -18db retur lo 56 % at the 2.4GHz, Hece propoed ew modified triagular lotted eirki gaket fractal atea ca be cover the WLAN ad RFID ISM bad. Fig.4 Retur Of The New Modified Triagular Slotted Sieriki Gaket Fractal Atea. Radiatio patter of the propoed atea i how i fig.4. I thi radiatio patter how x-z plae ad y-z plae at 2.45GHz from the fig.4. The propoed atea radiated i omidirectioal patter,thi radiatio patter combie both the E φ ad E θ compoet. Microtrip fed i excite the modified ierpiki gaket atea thi curret ditributio i how i fig.5.the imulated radiatio patter i imilar to the tadard triagular fractal dipole atea.the imulated atea gai 3.14 dbi for reoat frequecy 2.4GHz.
