Abstract In this paper, a novel structure of wearable antenna using clothing materials, suitable for

wearable application has been presented. The substrate of the designed antenna was

made of textile material, while radiating element and ground plane are made out of copper tape. To design a novel wearable flexible antenna which has high gain, efficiency,

good return loss. Improvement in the design is done by increasing the electrical length and area without increasing the size of the antenna. The simulations were carried out

using CST Microwave Studio software and the comparison of measured and simulated

results of proposed antenna have been studied. Measured and simulated results are in excellent agreement.

Keywords: Antenna, textile materials, wearable, CST microwave

Triple Band PIFA Antenna Using The DGS Method

Atul Nogia*, P. K. Singhal Department of Electronics Engineering, Madhav Institute of Technology

and Science, Gwalior, M.P., India

Abstract In this paper, a new design of a triple band Planner Inverted F Antenna (PIFA) with DGS, for mobile and wireless communication systems is presented. The PIFA antenna

consists of ground plate, patch antenna, feeding port and shorting plate connected to the ground plate. The designed antenna has been simulated with the help of the CST

(computer Simulation Technology) software microwave studio 2010. The simulated

results calculated for the resonant frequency, directivity, return loss, radiation pattern

and gain are obtainable and discussed.

Keywords: PIFA antenna, triple band antenna, return Loss, defected ground

Rectangular Patch Monopole Antenna with Different

Shaped Multiple Slots for Triple Band Frequency

Applications

Umang Supekar*, P.K. Singhal

Department of Electronics, Madhav Institute of Technology & Science, Gwalior, India

Abstract In this paper a rectangular patch microstrip antenna with different shaped multiple slots

behaves as a triple band monopole antenna. It is designed for 0.960311.0464, 1.37661.5797 and 2.16292.3708 GHz frequency bands. A rectangular patch monopole antenna with multiple slots, i.e., hexagonal slot and rectangular slot is fabricated on the glass epoxy (FR4 lossy) of dielectric substrate with relative permittivity (r) of 4.4, thickness of 1.6 mm, loss tangent of 0.02 with a ground plane, fed with a 50 rectangular micro strip feed line. In these antenna three different bands with three return losses measured below 20 dB in which one is below 50 dB within its impedance bandwidth along with omnidirectional radiation pattern. The novelty of this antenna is that no other antenna

gives triple bands with minimum return losses in just 03 GHz band spectrum. This prototype antenna having an omnidirectional radiation pattern is measured for frequency

range of 03 GHz. The measured reflection coefficients are far below of 10 dB. The simulated result and experimental results are analyzed and verified after comparison.
