This paper presents a novel way for achieving endfire radiation pattern using microstrip patch antenna array. The extensively used microstrip patch antennas i.e. rectangular and circular microstrip patch antennas, either single patch or in an array configuration do not have an endfire radiation pattern. The antenna array presented in this paper is designed by changing the geometry of the antenn...

In this paper, a new design technique for enhancing bandwidth that improves the performance of a conventional microstrip patch antenna is proposed. This paper presents a novel wideband probe fed inverted slotted microstrip patch antenna. The design adopts contemporary techniques; coaxial probe feeding, inverted patch structure and slotted patch. The composite effect of integrating these techniq...

A novel printed octagonal fractal microstrip antenna with semi-elliptical ground plane is presented for ultra wide band applications. The proposed antenna has a compact size of 20×20×1 mm³. The measured result of the antenna exhibits the ultra wide band characteristics from 2/9 to 14/2 GHz. In this paper, reducing antenna’s size by 35%, the same results were achieved, while small dimension frac...

This letter presents a miniaturized probe-fed elliptical microstrip patch antenna (PF-EMPA) targeting the 8.50-10.55 GHz band for radiolocation applications. The proposed design is composed of an elliptical patch inserted into an elliptical slot. In order to achieve our goals and control the impedance matching, we adjusted the offset distance from the elliptical patch to the side of the ellipti...

Microstrip patch antenna becomes very popular day by day because of its ease of analysis and fabrication, low cost, light weight, easy to feed and their attractive radiation characteristics. Although patch antenna has numerous advantages, it has also some drawbacks such as restricted bandwidth, low gain and a potential decrease in radiation pattern. In recent years, attention to use Electromagn...

The properties of the Koch island fractal boundary microstrip patch antenna are presented. The behavior at the fundamental mode and the existence of high-order modes that exhibit localized current density distributions is discussed. The main features are the size reduction of the patch resonating at the fundamental frequency when compared to Euclidean-shaped patches, and the application of loca...

The aim of this investigation is to improve the performance of a basic microstrip antenna array using a tree structure patch supplied by electromagnetic coupling. The developed network which contains two subnets, a distribution subnet and a scanning subnet, is considered as a first step to design an adaptive microstrip antenna for UMTS use. The patch distribution structure used in this experime...

In this paper, we present multiple L slots antenna for WIMAX and WLAN applications. wideband microstrip patch antenna for wireless applications. The coplanar waveguide fed microstrip patch antenna comprises of four rectangular patch array each embedded on three L slots and a Plus slot either on the patch or on the ground plane or on both the patch and the ground plane. The design results in red...

A single layer monpole slotted patch antenna is thoroughly simulated in this paper. Resonant frequency has been reduced drastically by cutting three equal slots which are same hexagonal structure at the upper right, upper left, lower left corner and a circle at the center from the conventional microstrip patch antenna. It is shown that the simulated results are in acceptable agreement. More imp...
