This paper presents a novel design of a microstrip patch antenna with compact nature and the study of various antenna parameters to suit the applications such as WiMax operating in the frequency range of 3.3 – 3.5 GHz and in other applications like fixed satellite services, maritime mobile services etc. covering 2 4 GHz of S-band frequency spectra. It is experimental observed that by placing st...

This paper presents a CPW-fed compact inverted L shaped microstrip antenna for wireless applications. The proposed antenna provides an omni directional radiation pattern and it utilizes the concept of coplanar wave guide (CPW). The main motive is to simplify the structure and to reduce the overall size of the antenna. This is done by loading the inverted L-strip over the conventional monopole p...

An ultra-wideband (UWB) self-complementary planar bow-tie antenna (SCPBTA) is proposed. The antenna consists of a printed conical horn-shaped (CHS) radiator and a counterpart CHS slot etched on a rectangular ground plane. The printed CHS radiator is connected directly to the 50Ω microstrip line by bending the end portion of the feed line. As a result, the antenna has a simple structure which do...

A compact annular ring microstrip antenna was proposed for a wireless sensor network (WSN) application in the 2.4 GHz band. In this paper the major considerations of the conformal antenna design were the compact size and the impact on antenna's performance of a steel installation base. By using a chip resistor of large resistance (120 Ω) the antenna size was reduced to 38% of that a conventiona...

A WLAN band notched compact ultra-wideband (UWB) microstrip monopole antenna with stepped geometry is proposed. A L-slot loaded modified mushroom type Electromagnetic Band Gap (EBG) is designed, analyzed and used to realize notched band characteristics for wireless local area network (WLAN) in the UWB frequency range. The proposed antenna having partial ground plane is fabricated on a low cost ...

A single feed quad band compact rectangular microstrip antenna is presented in this paper. L slit is introduced on the edge of the patch to reduce the resonant frequency. For the proposed antenna four resonant frequencies are obtained at 2.5 GHz, 3.46 GHz, 4.76 and 5.68 GHz with bandwidth of 11.26 MHz, 26.29 MHz, 92.11 MHz , 50.62 MHz &return loss –29.09 dB , -15.23 dB, -23.73 dB & -19.93 dB re...

In recent years, the application of radio frequency identification (RFID) operating in the ultra-high frequency (UHF) band (860-960MHz) are expanding exponentially, due to the advantages such as long reading distance, high data transfer rate, and small tag size. So the design of a CP tag antenna with broadband characteristic is presently one of the most challenging topics. This project presents...

This paper presents a novel structure of a frequency-reconfigurable microstrip antenna fed with an aperture-coupled technique and stacked patch technology. The proposed antenna design has a unique structure; the radiating elements (top and bottom patch) are sorted in stacked substrate layers to indicate the different operating frequencies. One PIN diode switch integrated at the feedline is reco...

In this paper, a novel design of a compact planar ultra wide band (UWB) monopole antenna with triple band notched characteristics has been presented. The antenna has a unique shape and has been fed through a 50 Ω microstrip feedline. The strength of the antenna lies in three band notched properties for WiMax system at 3.3 3.7 GHz, WLAN IEEE 802.11a at 5.15 5.85 GHz and X band satellite communic...
