Microstrip antenna is gathering a lot of interest in communication systems. Genetic algorithm is a popular optimization technique and has been introduced for design optimization of proximity coupled antenna. Patch length, patch width are taken as optimization parameters. Return loss and radiation pattern for the optimized antenna are verified using IE3D software. Accuracy of the results encoura...
A dual microstrip meander slot antenna is presented for Wireless Local Area Network (WLAN) application. The proposed antenna comprises a rectangular microstrip patch element embedded with two meander slots. The parametric study is performed to investigate the characteristics of microstrip patch antenna with double meandered slots compared to one without any meander slot. Microstrip patch antenn...
The microstrip patch is one of the most preferred antenna structures for ofordable and compact design for wireless system and RF applications. This paper compares the rectangular patch antenna and equilateral triangular microstrip antenna in terms of their return losses and radiation pattern. For the comparative study the Ansoft HFSS V11 is used. Keywords— rectangular micro strip antenna, retur...
This paper presents air gap aperture coupled microstrip antenna for dual-band operation over the frequency range of (2.9 to 6.0 GHz). This antenna differs from any other microstrip antenna with their feeding structure of the radiating patch element. Input signal couples to the radiating patch trough the aperture that exists on the ground plane of microstrip feed line. The dual-band achieved by ...
This paper presents a single-patch broadband microstrip Sshaped patch antenna. Microstrip S-shaped patch antenna, fed by a coaxial feeding. The antenna is designed by inserting two slots into rotated square patch then it look like english letter S. Because of the slots and thick substrate, bandwidth of antenna is increased. The proposed antenna is operating at centre frequency of 4.3GHz (i.e ne...
Compact shorted 1350 Sectoral microstrip antenna derived from 2700 Sectoral microstrip antenna is proposed. On thicker air substrate (h > 0. 1?0) it yields bandwidth of more than 350 MHz (35%). To increase the bandwidth, its rectangular slot cut variation is proposed. The slot reduces the resonance frequency of higher order TM1/4,1 mode of the shorted patch and along with fundamental TM1/4,0 mo...
The triangular geometry of the microstrip patch is one of the most common shapes having a wide range of applications ranging from circuit elements to modern wireless antennas. Recent survey of open literature shows interesting development of this patch as novel circuit elements and antennas. In this paper, a very comprehensive review of the applications and investigations on triangular microstr...
The spectral-domain approach is applied to the analysis ofa fonr microstrip patch resonator array that is printed on anisotropicsubstrate. Basis fnnctions are carefnlly chosen to accurately representthe cnrrent distribution on each patch, corresponding to every symmetryof the structure. Ample numerical results are presented which show theeffects of geometrical and anisotropi...
A new Sierpienski & Crown Square Fractal Shapes Slotted Microstrip Patch Antenna is proposed. A patch antenna is a narrowband, wide-beam antenna. These antennas are low profile, conformal to planar and non-planar surface, simple and inexpensive to manufacture using modern printed circuit technology, mechanically robust when mounted on rigid surface, compatible with MMIC designs and when the par...
The microstrip patch is one of the most preferred antenna structures for low cost and compact design for wireless system and RF application. Dual-Band antennas are of a relative interest since they can support multiple communication systems. In this paper we present design of a novel compact small size microstrip antenna suitable for dual-band operations. By loading properly arranged slots on a...
