A dual-band antenna by use 2 × 2 patch array with L-slot is presented for simultaneously worldwide interoperability for Microwave Access (WiMAX) and wireless local area network (WLAN) application. This 2 × 2 Patch Array with L Slot Antenna is targeted to achieve the gain more than 2 dB for both frequencies by using array technique design. The antenna design structure has been modified by adding a...
This paper explains the initial study on a nature-inspired cuckoo search (CS) algorithm to optimize symmetric linear array geometry with minimum sidelobe level (SLL) and/or nulls control. The CS algorithm is primarily based on the obligate brood parasitic behaviour of some cuckoo species in combination with the Lévy flight behaviour of some birds and fruit flies. The CS metaheuristic approach is straightforward...
Ceramic microstrip patch antenna formed using Barium Strontium Titanate (BST) has been investigated. The Computer Simulation Technology (CST) Microwave Studio is used for the simulation. We measured the gain of antennas with two, four, and six elements array of BST antenna and found that the gain of an six elements of BST array antenna was enhanced by about 2.126 dB gain over the four elements of...
This paper explains the synthesis technique of symmetric linear array geometry with minimum sidelobes and null control using the cuckoo search (CS) algorithm. The CS is a new nature-inspired evolutionary algorithm capable of solving general N-dimensional, linear and nonlinear optimization problems. The newly evolved CS metaheuristic algorithm is easy to understand and to use, which requires simple...
A microstrip patch antenna formed from Barium Strontium Titanate (BST) ceramics has been investigated. The Computer Simulation Technology (CST) Microwave Studio is used for the simulation. We measured the gain and directivity of antennas with four, six and eight elements of BST array antenna and found that the gain of an eight elements of BST array antenna was enhanced by about 0.06 dBi of directivity...
The superior ferroelectric properties of Bi4Ti3O12 (BIT) among bismuth-layer-structured ferroelectric compounds have attracted intense interest, making these structure some of the most competitive candidates for piezoelectric devices against lead containing materials. This paper presents the utilizing of ferroelectric material on antenna application. Ferroelectric that had been used on the proposed...
