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...

Microstrip patch antennas are well known for their advantages in terms of small weight, low profile and ease of manufacture. However, the main limiting factor in implementing these antennas in many applications is their low impedance bandwidth (typically 2-3%). One popularly used technique of enhancing the bandwidth is to use multi-layered microstrip[1,2]. The most widely accepted structure in ...

This paper presents the design of a 2 x 2 microstrip array antenna suitable for wireless applications. The proposed antenna comprises of 4 rectangular patches where diagonal patches have the same length and width. A larger bandwidth and the desired resonant frequency are achieved because of a reduction in the quality factor (Q) of the patch resonator, which is due to less energy being stored be...

Abstract—The patch shape influence on the radar cross section (RCS) of a cylindrical microstrip antenna (CMA) is discussed. The RCS of the CMA is evaluated from a plane wave scattering problem solution to a cylindrical microstrip antenna. The method of moments is employed in the spectral domain using sub-domain basis functions. It is shown that the patch shape has a pronounced effect such that ...

Design of rectangular microstrip patch antenna loaded with “different C patterns” left-handed metamaterial structure has been proposed. The proposed metamaterial structure is designed at a height of 3.2 mm from the ground plane for L-band (1 GHz-2 GHz) applications. The most interesting feature of the design is the ability of enhancing the gain and total efficiency of the antenna without effect...

This paper introduces a new configuration of compact, triangular- and diamond-slotted, microstrip-fed, low-profile antenna for C/X band applications on polytetrafluoroethylene glass microfiber reinforced material substrate. The antenna is composed of a rectangular-shaped patch containing eight triangles and two diamond-shaped slots and an elliptical-slotted ground plane. The rectangular-shaped ...

The paper presents best matching between simulated and measured results of broadband Rectangular Patch Microstrip Antenna with Rhombus Shaped Slot (RPMARSS) for the WLAN Application. This antenna is designed on glass epoxy FR-4 substrate. The performance of this antenna is also compared with that of a simple rectangular patch antenna. The simulated results of this antenna are optimized by varyi...

Bandwidth of proximity fed E-shaped microstrip antenna has been increased by gap-coupling pair of rectangular slot cut rectangular microstrip antennas along its radiating edges. The patch and slot dimensions were optimized to cover 800 – 1200 MHz frequency band. In this paper, a detail analysis to study the effects of slot and patch dimension on the broadband response in desired frequency band ...

The multi-band microstrip antennas are realized by cutting more than one slots at an appropriate position inside the patch or by placing the open circuit stub on the edges of the patch or by using the combination of slots and stub. In this paper, an analysis to study the multi-band response in stub loaded two half U-slot cut rectangular microstrip antenna is presented. The first half U-slot in ...

270 Abstract— A single layer, single feed compact rectangular antenna is proposed. Resonant frequency has been reduced drastically by cutting unequal rectangular slots at the edge of the patch & a circle in the middle. The width of the rectangular slots is different to improve the gain bandwidth performance of the antenna. The antenna size has been reduced by 41.8% when compared to a convention...
