A modified circular patch antenna design has been proposed in this paper, the bandwidth of this antenna is optimized using the genetic algorithm (GA) based on fuzzy decision-making. This design is simulated with HP HFSS Program that based on finite element method. This method is employed for analysis at the frequency band of 1.4 GHz- 2.6 GHz. It gives good impedance bandwidth of the order o...

This paper proposes a micro-strip patch antenna operate on the dual frequency bands. The proposed antenna design consists of U slotted patch with direct coaxial probe feed technique. The U slotted patch offers a low profile, high gain, broad band and compact antenna. The proposed designs are based on patch loaded with U slots in the form of cut from the sides and center of the rectangular and c...

A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...

Microstrip patch antennas are light weight and low profile antennas so use of these kind of antennas are more easy in portable and small communication devices where size is concerned . In this paper the analysis of T –slot rectangular microstrip patch antenna is presented. The antenna is designed for wide applications in C-band space communication and wireless LAN communication systems. The ban...

Patch antenna with double notches and triangular tapered feeding line has been investigated. It is observed that broadband matched double-notched patch antenna is suitable for tri-band operations from simulation and experimental results. It shows a measured return loss well below –10 dB in all three-frequency bands of operation. It has also been observed that the double notched conventional rec...
