Main advantage of fractal is compact size, multiband, and high gain [9,10]. It can be used in the form of branching of tree leaves, plants,

1.3 Microstrip Patch Antenna In its basic form, a Microstrip Patch antenna consists of a radiating patch on one side of a dielectric substrate which has a ground plane on the other side as shown in Figure.1.1 Figure 1.1: Microstrip patch antenna The patch is normally made of conducting material such as copper or gold and can take A circular microstrip patch antenna with L-slit is introduced at the right edge of the patch to reduce the resonant frequency. Introduction of L-slit reduces the size of antenna and increase the bandwidth compared to conventional circular microstrip patch antenna. Moreover, size reduction is used to enhance the return loss and bandwidth. The shape of rectangular patch antenna is shown below in Figure 2. Rectangular Microstrip patch has been designed with ε r = 4.4 and h = 1.6 mm. We designed the rectangular patch for 2.4 GHz, with dielectric substrate of Figure 1. Structure of a microstrip patch antenna. Fig. 1. Structure of a microstrip patch antenna. For simplicity of analysis, the patch is generally square, rectangular, circular, triangular, and elliptical or some other common shape. For a rectangular patch, the length 𝐿 of the patch is usually in the range of 0.3333 0 < 𝐿< 0.5 0, where 0. is the free space wavelength. A microstrip or patch antenna is a low-profile antenna that has a number of advantages over other antennas: it is lightweight, inexpensive, and electronics like LNA’s and SSPA’s can be integrated with these antennas quite easily. Rectangular patch. The most commonly employed microstrip antenna is a rectangular patch which looks like a truncated microstrip transmission line. It is approximately of one-half wavelength long.

Rectangular Microstrip Patch Antenna Using Air as Substrate for S-Band Communication OPEN ACCESS JEMAA 41 Figure 4. VSWR plot of proposed antenna operating at 3.52 GHz. Looking at Figure 4, it can be observed that the meas-ured value of VSWR is 1.0328. 5. Conclusion This paper has successfully designed arectangular patch antenna operating at 3 Some noteworthy observations are apparent from Figure 3. First, the bandwidth of the patch antenna is very small. Rectangular patch antennas are notoriously narrowband; the bandwidth of rectangular microstrip antennas are typically 3%. Secondly, the microstrip antenna was designed to operate at 100 MHz, but it is resonant at approximately 96 MHz. This shift is due to fringing fields around the antenna, which makes the patch seem longer.

May 06, 2009 · Abstract: The microstrip patch antenna is a popular printed resonant antenna for narrow-band microwave wireless link applications such as radio frequency identification (RFID) systems that require semi-hemispherical coverage. In this paper, a 865 MHz microstrip patch antenna fed by a microstrip line designed on a substrate is considerably studied and thoroughly analyzed.

Project Name: "Des A New Design Formulae for Feed Line Dimensions of the Rectangular Microstrip Patch Antenna by using Equivalent Design Concept January 2015 DOI: 10.1109/ICSPCom.2015.7150629 A slot-loaded microstrip patch sensor antenna is proposed to enhance sensitivity in measuring the permittivity of planar materials. A thin rectangular slot was etched along the radiating edge of a rectangular patch antenna fed by a microstrip transmission line. Two resonant frequencies were created at a lower frequency compared to the single resonant frequency of a conventional ordinary patch patch antenna are -29dB, 150o and 4dB respectively. directional,Both the antennas were fabricated using FR4 of dielectric constant 4.6 and thickness 1.6mm.

ANN can also be used to calculate different parameters of circular microstrip antenna such as resonant Microstrip Patch Antennas (or simply patch antenna) are increasingly useful because the antenna is printed directly onto a circuit board. Additional benefits of patch antennas is that they are easily fabricated making them cost effective. Their low profile design, often square or rectangular, allows them to be mounted to flat surfaces.
