Abstract – This research has been done on Microstrip patch antenna due to its imperative properties such as light weight, low profile, simple to fabricate and easy to integrate with RF devices. In this paper, dreadfully tiny dimensional triangular shape microstrip antenna is designed by using double doping LANTHANIDIES. The substrate permittivity (dielectric constant) is studied by responsible capacitance at corresponding frequency range. This antenna is compact, small, simple to design and fabricate with proposed substrate material. The performance of the designed antenna was analyzed in term of its bandwidth, gain, directivity, return loss, and radiation pattern.
Key Words: Triangular shape, Microstrip patch antenna, Lanthanides, Return loss, Band width
The radiating patch conductor is generally of copper and can assume any shape square, rectangular, circular, elliptical, triangular or any other desired configuration. Square, rectangular, dipole and circular are the most common because of ease of analysis, simple fabrication and their attractive radiation efficiency.
2. DESIGN OF TRAINGULAR MICROSTRIP
PATCH ANTENNA The Microstrip patch antenna has been designed with three layers such an ground plane, substrate and patch. From these the lanthanides are used for substrate material preparation. The microstrip line feed is connected with 50ohm impedance for higher efficiency. Table -1: Dimension of Isosceles Triangular
1. INTRODUCTION Microstrip patch antennas have been attractive due to their conformal properties. These antennas are preferred for satellite and mobile communication due to their advantages of small size and low manufacturing cost. A microstrip antenna consists of a very thin metallic patch placed a small fraction of a wavelength above a conducting ground plane. The strip and ground are separated by a dielectric sheet referred to as substrate. The radiating element and feed lines is normally photo etched on dielectric substrate.

2.1 Patch design and Layout:
The design of isosceles triangular shape microstrip patch antenna design with above mentioned dimension with microstrip line feed technique. The layout is simulated in HFSS software with 3GHz operating Frequency. Three dimensional layout is showing in Fig 2. The dielectric substrate is used for design of substrate layer with permittivity 0.9. The substrate height is 1.5mm. These parameters are decides the efficiency of antenna. Base and height dimension are decided by substrate dimension and frequency.
