A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...

A design method for a compact square loop antenna fed by a microstrip (MS) line for indoor digital television (DTV) applications is proposed. The proposed antenna consists of a square loop, circular sectors, and an MS line. The square loop combined with circular sectors is printed on one side of a substrate, and a 75 ohm MS line is printed on the other side. The circular sectors are used as a w...

This paper proposes the compact microstrip antenna with high gain and broad bandwidth by using Bi-polar mechanism. In this mechanism the surface is increased and the losses are reduced. This antenna uses the MATLAB simulator to calculate the parameters and from results it is found that the bandwidth is wider by using this mechanism. This antenna is used for C-Band application, which is the part...

The electromagnetic band gap structures are widely used to suppress pronounced surface waves in antennas with thicker substrate and higher dielectric constant. This paper reviews various application of Electromagnetic band gap structure in microstrip antenna, a band gap characterization of an electromagnetic bandgap structure along with the explanation of various reported configurations of comp...

A compact size, multiband 2x2 array of circular microstrip antenna has been proposed. The antenna array consists of Genetic Algorithm (GA)optimized, annular slotted circular microstrip antenna elements using probe feed. The spacing of elements has also been optimized using GA in the two directions. The performance of the antenna array has been studied with different shape parameters. The optimi...

A new dual-polarized slot-coupled microstrip patch antenna is presented, which can achieve high-isolation low crosspolarization levels, a wide bandwidth, and low backward radiation levels. The coupling slot is an H-shaped slot. For wide bandwidth and easy integration with active circuits, it uses the slot-coupled stacked microstrip patches. The theoretical analysis is based on the finite-differ...

The increasing demand in portable devices with wireless connectivity provides a challenge to design a RF front antenna. Microstrip patch antennas are widely used because they are of light weight, compact, easy to integrate. However the serious problem of patch antenna is their narrow band due to surface losses and large size of patch for better performance. So for the antenna miniaturization an...

A compact printed dipole antenna with wide impedance bandwidth is proposed in this paper. This antenna consists of a pair of radiation metal arms and a microstrip-to-slotline transition structure. At the end of the feeding slotted line, a beveled slot with stepped connection structure is designed to realize an offset feeding structure for feeding the dipole antenna. By using the beveled offset ...

By virtue of their ability to resonate at a wavelength much larger than the maximum dimension, Split-Ring Resonator (SRR) cells can be densely stacked to create energy harvesting arrays having per-unit-area power efficiency higher than a single SRR cell. While the concept of using metamaterial particles for electromagnetic energy harvesting had been demonstrated in our earlier work, the overall...
