Javeed Ahammed, R. Praveena 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 0.12λ 0 × 0.2λ 0 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. Keywords: omni- direction, E- shape, CST, FR4 material, Meander Line. I. INTRODUCTION As we use MIMO antennas even in near and far field operations which occupies larger area and power consumption even bandwidth is very less as compared to our proposed antennas these are slotted meander line antennas. In number of countless applications we use these Ultra High Frequency (UHF) bands including in LTE700/GSM850/900 band [1], wireless M-Bus [2], and wireless body area network [3]. As we use the UHF frequencies there is more size of antenna is required due to its larger wavelength. So, particularly for low frequency band signals there should be minimized because the size of antenna for this operating band is very large. Before meander line for low frequency bands we use to have wired antennas for even UHF range frequency also. But there are difficulties in integration with circuit boards of microwave integrated and have manufacturing in complex and clumped manner. Nevertheless, we have a solution for this that is using planar antennas which can overcome those issues but bulk size does matters. Revised Manuscript Received on December 05, 2019. MD.

So, based on slotted meander line a monopole printed antenna of miniaturized size patch at 900MHz is simulated in this paper based on CST tools for Ultra High Band frequencies. For antennas impedance matching we develop a ground of small square defected structure. As we see the miniaturized evolution techniques by using slotted meander line reduce the power consumption required the size of this meander line miniaturized antenna is 46 × 72 mm 2 or about 0.12λ 0 × 0.2λ 0 . II. MEANDER LINE ANTENNA This antenna has lots of advantages and disadvantages which we discuss further and as for now the antenna design model is evaluated in this section. Figure.1 is a meander line antenna structure which is a fabrication model on FR-4 material of substrate and ε r = 4.2 which is for constant dielectric, and height of substrate is denoted by h=1.4mm and which is tangent of loss 0.01 our antenna structure is having microstrip line which is 50 Ω feed that is backed partially. For improving the impedance we add the small rectangular slot on antennas back side with parameters of length and width of 3.5 mm is realized on the back side of the antenna to improve the impedance matching of the design.
