    A Review on Circular Microstrip Patch Antenna with Slots for C Band Applications. Nidhi M. Thaker, Vivek Ramamoorthy. Abstract — Over the past one decade, there is a rapid growth in development of various applications involving wireless communication. A rectangular microstrip antenna containing an array of narrow L-slots and inverted L-slots is described for multifrequency operation. The patch was designed for TM mode of excitation at GHz and is fed with a coaxial probe from the ground plane. The slots are cut on the patch at two opposite oghd.kushovaschool.ru: Antara Ghosal, Antara Ghosal, Sisir Kumar Das, Sisir Kumar Das, Annapurna Das, Annapurna Das.

    A simple slotted structure without any additional electronic circuit was designed for multifrequency operation. The Ansoft HFSS software tool was used for the simulation and optimum design of the antenna on a FR-4 dielectric substrate above a ground plane.

    It is observed that the final configuration produces very good performance at penta frequencies: 1. A single patch antenna provides a maximum directive gain of around dBi.

    It is relatively easy to print an array of pafch on a single large substrate using lithographic techniques. Patch arrays can provide much higher gains than a single patch at little additional cost; matching and phase adjustment can be performed with printed ahtenna feed structures, again in the same operations that form the radiating patches. The ability to create high gain arrays in a low-profile antenna is one reason that patch arrays are common on airplanes and in other military applications.

    Such an array of patch antennas is an easy way to make a phased array of antennas with dynamic beamforming ability.

The methods developed for efficient wideband patch antenna design are based on one or more of the following principles: A. Thick substrates of low permittivity are used. B. A scheme is devised to reduce the mismatch problem associated with thick substrates. C. By means of parasitic elements or slots, either new resonances.

    An advantage inherent to patch antennas is the ability to have polarization diversity. Patch antennas can easily be designed to have vertical, horizontal, right hand circular RHCP or left hand circular LHCP polarizations, using multiple feed points, or a single feedpoint with asymmetric patch structures.

    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. When air is used as the dielectric substrate, the length of the rectangular microstrip antenna is approximately one-half of a free-space wavelength. As the antenna is loaded with a dielectric as its substrate, the length of the antenna decreases as the relative dielectric constant of the substrate increases.

    The resonant length of the antenna is slightly shorter because of the extended electric "fringing fields" which increase the electrical length of the antenna slightly. An early model of the microstrip antenna is a section of microstrip transmission line with equivalent loads on either end to represent the radiation loss.


    The dielectric loading of a microstrip antenna affects both its radiation pattern and impedance bandwidth. As the dielectric constant of the substrate increases, the antenna bandwidth decreases which increases the Q factor of the antenna and therefore decreases the impedance bandwidth. This relationship did not immediately follow when using the transmission line model of the antenna, but is apparent when using the cavity model which was introduced in the late s by Lo et al.

    These slots act as an array and have the highest directivity when the antenna has an air dielectric and decreases as the antenna is loaded by material with increasing relative dielectric constant.

    The half-wave rectangular microstrip antenna has a virtual shorting plane along its center.

    This may be replaced with a physical shorting plane to create a quarter-wavelength microstrip antenna. This is sometimes called a half-patch. The impedance bandwidth is slightly lower than a half-wavelength full patch as the coupling between radiating edges has been eliminated. The PIFA is common in cellular phones mobile phones with built-in antennas.

    The PIFA is popular because it has a low profile and an omnidirectional pattern. The shorting plane of the half-patch is reduced in length which decreases the resonance frequency.

    On some phones, grounded parasitic elements are used to enhance the radiation bandwidth characteristics. From Wikipedia, the free encyclopedia. Main article: Patch antenna.
