Microstrip patch antennas represent one family of compact antennas that offer a conformal nature and the capability of ready integration with communication system’s printed circuitry. In this project, a 2.4 GHz circular polarization microstrip antenna is designed, constructed and measured. The selected microstrip antenna is a dual –fed circular polarized microstrip antenna. The antenna consists...
A planar magnetoinductive (MI) waveguide loaded rectangular microstrip patch antenna is presented and discussed. The MI waveguide consists of two planar metamaterial split squared ring resonators (SSRRs) placed in between two microstrip lines. The backward wave propagation takes place through this structure. The rectangular microstrip patch antenna is magnetically coupled to the MI waveguide. T...
This paper presents the design of rectangular, fractal Microstrip patch antenna and their backscattering reduction. These antennas have been designed on εr = 4.3, h = 1.53 mm substrate with rectangular patch dimension 36.08 x 29.6 mm and its 2 iterative fractal patch. The experimental resonant frequency of 2 iterative fractal patch is observed 2.11 GHz in comparison to rectangular patch 2.42 GH...
Over the past years microstrip resonators have been widely used in the range of microwave frequencies. In general these structures are poor radiators, but by proper design the radiation performance can be improved and these structures can be used as antenna elements (Damiano & Papiernik, 1994). In recent years microstrip patch antennas became one of the most popular antenna types for use in aer...
Different feeding techniques of microstrip patch antennas with different spiral defected ground structures are presented in this paper. The investigated structures illustrate some merits in designing multi-electromagnetic band-gap structures by adjusting the capacitance and changing the inductance through varying the width and length of spiral defected ground structure. Then by applying the thr...
A single layer monopole hexagonal patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting two equal slots which are the combinations of two triangular and one rectangular slot at the upper right and lower left corner and middle point symmetrical Y-junction slot located from the conventional microstrip patch antenna. Compared to a conventio...
Generally microstrip patch antenna (MPA) is used in modern communication devices and day-to-day communication is done through it. Study of literature of past few year shows that, the leading work on MPA is design compact size broadband microstrip antenna, but inherently MPA have narrow bandwidth so various techniques are engaged to enhance bandwidth. This review paper demonstrates some commonly...
Microstrip antennas have been widely used for aerospace applications and in small portable wireless communication equipments because of their compactness, light-weight, low-profile, and relative ease of fabrication. The small size is an important requirement for portable applications. There are various types of microstrip patch configurations. In general, the size of a microstrip patch is about...
A simple, compact, slot loaded stacked wideband microstrip patch antenna is presented in this communication. The radiating element consists of a rectangular patch with a Tshaped slot and is fed by a 50 Ω microstrip line. The proposed antenna is simulated using IE3D software, 12.32 version of Zeland. The simulated results show that the antenna can exhibit wideband characteristics. The impedance ...
Abstract : Microstrip antennas or patch antennas are popular for their attractive features such as low profile, low weight, low cost, ease of fabrication and integration with RF devices. Micro strip antennas have been found favorable because they are inexpensive to manufacture and compatible with monolithic microwave integrated circuit designs (MMIC). They are usually employed at UHF and higher...
