In this work investigation of Radiation Characteristics, Return loss, Directivity are simulated and practically examined. A five-element Yagi antenna fed with co-axial feed and made of aluminum is developed in this work. About 40% of size reduction is obtained by rearranging the directors and by decreasing the diameter of the elements.

Then T is called a ternarysemigroup if being existence a mapping from T T T to T which maps (pqr) [ pqr] satisfying the condition :[(pqr) st] = [ p(qrs)t] = [pq(rst)] for all p, q, r, s, t T. Definition 2.2: An idempotent component e T is said to be left (or lateral or right) identity of the if eaa = a(or aea = a or aae = a) for all a T. Left (or lateral or right) identity may not be unique. But if e is an identity (i.e. e plays the role of left lateral and right identity simultaneously) then e is unique. V. Jyothi et al.

As this is a wearable type it should have low weight, low profile and low cost. In this paper we have designed Microstrip rectangular patch antenna used for this application. Cotton Textiles with different dielectric values are used as substrates for this antenna. The antenna is fed with co-axial feed. Here we have examined the radiation characteristics, return loss and gain which are the critical parameters of wearable antenna for monitoring and diagnosing patient's condition. These are performed by using ANSOFT HFSS.

In this work we have designed a Edge Serrated Microstrip Patch antenna used for these applications has been modeled on FR4 substrate as a dielectric medium which has a relative permittivity value of 4.4. The proposed antenna was resonating at two different frequencies in L & S band Microwave frequency ranges. This antenna was fed with coaxial feeding and was designed in a software HFSS.

In order to meet these requirements in this paper we have designed a microstrip edge serrated rectangular patch antenna used for these applications. Here we have used silicon as substrate which has a relative permittivity of 11.9. This antenna was energized by using coaxial feed. The proposed model was designed by using a software HFSS.
