Micro strip patch antennas are widely used in compact, conformal and lowcost wireless applications due to its advantages over conventional antenna. Literature study of last few decades of micro strip patch antenna (MPA) shows that the different techniques are used to design a small size micro strip patch antenna. In this paper survey is conducted on different antenna designing methods like E sh...

In recent years, a large number of dual-band antennas have been developed for wireless applications [1]-[6]. Most of these dual-band antennas are used for mobile terminals, such as cellular phones or laptop computers. For such applications, the desirable radiation patterns are usually omnidirectional. A unidirectional radiation pattern is sometime required for wireless base station and/or acces...

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...

This work focuses on design and analysis of microstrip patch antenna as well as effect of slots made on patch antenna to improve the bandwidth. A microstrip line fed, dual slot, triple band, rectangular microstrip patch antenna is designed. The designed antenna is most suited for C band, X band and KU band applications. The return loss is below −10 dB in triple band with 1GHz bandwidth in the r...

In this article, a novel and compact ultra-wideband (UWB) planar antenna is presented. This antenna consists of an annular patch and a 50 microstrip feed line. The 3.5/5.5GHz dual band-notched characteristic gets achieved by etching a C-shaped slot in the patch and complimentary split ring resonator (CSRR) structure in the ground. The measured results show that the proposed antenna can achieve ...

A novel design of Dual band triangular serrated micro strip patch antenna was designed with different models of serrations and their simulation results are presented in this paper. Equal spaced serrated triangular shapes are etched on four sides of the patch and its performance characteristics are simulated. The number of elements on each side of the antenna is taken as 5,6,7,8 and all the mode...

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...

Development of small antennas for mobile phones has received a lot of attention during the last few years due to size reduction of the handsets, requirements to keep the amount of RF power absorbed by the user below standardized levels regardless of the handset size, and introduction of multimode phones. Single-band and dual-band phones in which the external whip or helix antenna has been repla...

A dual-band Planar inverted-F antenna (PIFA) for wireless applications has been presented in this paper. The proposed antenna is compact in size and design on FR4 substrate. The antenna consists of a slotted radiator supported by shorting walls and a small ground plane. Square shaped slot in radiating patch have been used to introduce dual band operation into the proposed antenna. The structure...

This study presents a new design of patch antenna with Human face shaped slot on the patch. This antenna has dual operating bands and suitable for wireless and C-band application. With a simple design configuration and the human face slot form on patch, the proposed antenna can be used in multiband wireless operations, covering the mobile IMT (3400-3600 MHz), C-band (3400-4200 MHz) and WiMAX (2...
