Efficiency in Bandwidth by using Meander Line Antennas Simulation

Abstract

In communication technology antennas plays a major role and now a days it has tremendous demand we do have different types of antennas for efficient transmissions discuss about a monopole antenna which is printed of meander line that is used for very low frequency operations of about 900 MHz With partially defected ground plane is backed with E-shaped meander line antennas of double structure is obtained by numerous slots evaluation which is the novelty of this design. By using this monopole antennas fabrication we can reduce the size of antenna and can have less operating frequency which is drastically reduced by these slots and meander lines. By this proposed design we can achieve 70% of reduction in size of antenna as conventional antennas compared. The size is of 42.2mm× 70 mm or 0.12λ0 × 0.2λ0 is obtained to antenna which is very reduced by this model. For having simulation performance valid we use FR4 substrate material for fabrication of antenna and is low cost. After simulation we can observe that the radiation pattern for this antenna is omni-directional measured with bandwidth impedance of 40 MHz with the -1dB gain which is maximum. We use CST Tool for simulation and fabrication technology is as simple even with this FR4 material.
