This paper presents comparison of rectangular micro strip patch antenna and E-Shaped micro strip patch antenna operating at 2.45GHz. Two parallel slots are made into the basic rectangular patch design of micro strip antenna which resulted into desired E-shaped patch. The basic design consist of inset feed type and we have used dielectric substrate Fr4 epoxy whereas E-shaped patch consist of coaxial probe and RT Duroid as substrate. Both the designs have been implemented using HFSS software. On comparing the parameters of both the antenna’s design, it was observed that E-shaped patch antenna has enhanced gain and return loss, hence the antenna with enhanced parameters is considered, the better one.

Height of the dielectric substrate material for a microstrip patch antenna is utterly important in terms of controlling bandwidth as well as surface wave. In this paper we have presented a comparative study of effect of height in the performance parameters of Rectangular Shaped Microstrip Patch antenna. The antennas were simulated for purpose of the application of wireless LAN for resonance frequency 2.45GHz. Five antennas with different heights were designed using same dielectric substrate material with relative permittivity of 2.84 for the analysis of their performances. Coaxial Probe-feed methods are used for feeding techniques. This paper along with the comparison of performance parameters like VSWR, Reflection coefficient, Bandwidth, Impedance, Mismatch loss, Directivity, Gain and Field, also presents the effect of substrate height in design parameters like width, length, feed point location, ground dimension for each patch antenna. This study was carried out by using FEKO, Electromagnetic solver software which uses Method of Moments (MoM) technique.

The antenna has been designed using substrate of FR4 material having dielectric constant of 4.4 with a conducting radiating patch on the substrate and a conducting ground plane on the bottom side of substrate. The ground plane has been partially reduced to improve the antenna bandwidth.

The antenna has bandwidth of 3.40 GHz and VSWR of less than 2. The antenna has been successfully fabricated and tested. It has been observed that the practical results obtained by testing the fabricated antenna using Network analyzer E5071C closely matches with the theoretical results obtained by simulating the antenna design in CST MWS 2010.

This paper is presentation of designed different diodes loaded active model dissimilar geometries of micro strip patch antennas. As known, mikrostrip patch antennas have complex impedance and its impedance changes with frequency. Because of this, imaginer part of micro strip patch antennas is minimized by effect of diodes having capacitive reactance thus maximum power radiating is occurred. The aim of this project is to present different diodes loaded patch antenna for ISM 2.4 Ghz and to indicate active antenna performance according to influence of locations and dc biasing of diodes then to compare the antenna parameters of passive models. Besides, this project is used three types of diodes which are schottky Barrier diodes, silicon variable capacitance diode and tuner diode and four diodes whose are bas70, bas83, bb619 and bb721. The simulation programmer is AWR Design Environment Microwave Office 2007 (MWO) whose analysis meted is moment (Mom). Finally, the antennas that are projected are ready condition for LAN application or wireless RF receiver-transmitter systems. Return loss of designed antennas are between -25.54 dB and -36.17 dB. Gain does not change a lot but results of VSWR and Input impedance is satisfactory when comparing the passive model's results.

Electromagnetic Band-Gap (EBG) structures are popular and efficient techniques for microwave applications; they are periodic metallic or dielectric materials. EBG may be combined with microstrip patch antenna to increase the directivity, the radiation efficiency and/or to suppress surface waves, to reduce the side lobes of the radiation pattern and to increase the bandwidth. In this paper, we study the influence of Unidimensionnel Electromagnetic Band Gap structure (1D-EBG) on the performances of an aperture coupled rectangular patch antenna. This 1D-EBG is chosen as two similar dielectric layers disposed above the patch. The return loss, radiation pattern, and directivity are studied using HFSS software. The simulation results show that the gain, directivity and S11 parameter of the antenna with dielectric superstrate layers are increased at X band (8–12GHz). Compared with the patch feed with the same aperture size but without dielectric layers, the performance of the proposed antenna is improved obviously.

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 does not require impedance matching networks. The antenna with a compact size of 32×38×1.2 mm3 can cover UWB spectrum from 3.1 to 10.6 GHz. The simulation time- and frequency-domain results obtained from HFSS simulator package are verified by experimental measurements. Measured results for the reflection coefficient, far-field radiation patterns, radiation efficiency, gain, and group delay of the designed antenna over the UWB spectrum are presented and discussed. Measured data show good concordance with the numerical results. Also, the fidelity factor is calculated in both E- and H-plane by using CST Microwave Studio. The obtained results in both time- and frequency-domain indicate that the proposed SCPBTA is a good option for most practical UWB applications.
