Arabic Abstract

في هذا البحث تم دراسة تأثير وضع نوعين من الهوائيات المستخدمة لأغراض التطبيقات العملية في نطاق الهوائيات الواقعة تحت تأثير الجسم و معرفة مقدار امتصاص الجسم للطاقة الكهرومغناطيسية المنبعثة من تلك الهوائيات و لقد تمت هذه الدراسة العملية بعد تصميم هوائيين أحدهما (MONOPOLE 2.45 GHz) و الآخر (MICROSTRIP PATCH ANTENNA 4.5GHz) ولقد تمت هذه الدراسة في مختبرات قسم الهندسة الكهربائية في جامعة لافبرا في المملكة المتحدة.

و تم استخدام جهاز المخصص لهذه القياسات و هو DSAY45 .

و يتكون هذا الجهاز من (TWIN PHANTUM) و يملىء بالسائل و لكلا الترددين على حده الذي يحتوي من مجموعة محاليل التي تقارب في صفاتها العضوية المكونات الجسم البشري .

English Abstract

The SAR value is an important parameter for the antenna designer, describing how much power absorbed by human tissue.

For electromagnetic radiators, there are threshold values for the maximum amount of power absorbed in different parts of the body.

If those limits are exceeded, the antenna or the whole cellular phone has to be redesigned, specific rate absorption is a value describing .In wireless Body Area Networks (WBANs), there are limits for frequencies which are used because of the interaction of body with electromagnetic waves which are received or transmitted form antennas which are used within the networks.

The two frequencies 4.5 and 2.45 which are from ISM and UWB are discussed in this paper.

By measurement the SAR effect on the twine phantom in EESE in Loughborough University/UK.

By Dosimetric Assessment System 4(DASY4).The positions of the two types of antennas (MSPA) and (MOA) on the body will effect on the measurements because the first type of antenna is horizontally polarization and the other is vertically polarization, also the depending on the.
