Yusuf micro strip array antenna helps to provide regionally goal and ease of management of antennas, so the array antem1a is widely used in real applications. Optimum array antenna needs to have minimum impedance mismatch. To remove the impedance mismatch the width of the feed line and transmission lines needs to be tuned across the network of feed lines However, l larger array tend to take up a lot of space due the network of feed lines in a large antenna array set up. Considering the reduction of impedance mismatch with different forms turns, we have designed an Patch Antenna and we that antenna the Array. We have considered various types of desing process by verifying those we have selected the best configuration for the feed line network.

Yeassen; Zaman, Tanima; Azmi, Fahmida today's world it has become a challenge to provide cellular connectivity as an -anywhere and anyhow" basis. Due to the vast increment of number of cellular. one users, multiple radio access technologies (RATs) are coming under same Every RAT is allocated with specific radio frequency bands in one core radio network The purpose of our proposal is to use these RATs in a heterogeneous network priority basis. This means whenever connectivity is requested by a moving user, he is provided with free channels of the available RATs through sharing radio resources. Thorough this procedure, maximum quality of service (QoS) can be provided to the users call blocking probability can be reduced. In our project we have used Common radio Resource Management (CRRM) algorithms. In our proposed model CRRM has used for call admission control and vertical hand over functions. Our proposed model is compared with Luo's Joint Scheduling Model. In our proposed model although GPRS and WLAN have been considered, but our model can be employed for heterogeneous networks consisting of any wireless communication systems This thesis submitted in partial fulfillment of the requirements for the degree of B.Sc in Electrical and Electronic Engineering of East West University, Dhaka, Bangladesh. 2009-10-29T00:00:00Z http://dspace.ewubd.edu:8080/handle/123456789/2156 Microwave Link Planning, Installing and Commissioning Hira, Avijit; Alam, Mahfuz In today's world it has become a challenge to provide cellular connectivity as an -"anytime, anywhere and anyhow" basis. Microwave link is one of the most important parts of this cellular service. Only a proper microwave plmming, installation and commissioning can provide the best service to the customers. The internship we did in TRX OPTIMIZATIONS, gave us the opportunity to learn about how the planning, installing and commissioning is really done in the practical field. So this report is about the topics that we have learned in our short intern period. Form this internship we have learned how to work in a team. We have also familiarized with a corporate environment. In our internship we have gathered lots of knowledge about many real life problems. Some of these problems are very interesting and not included in textbook .

Lots of organizations are installing their own power system. Transmission of power is a major part of power system .Bus-bar, conduit and cable installations are important for the transmission of power. This internship provided the opportunity of planning and monitoring the installation of the power system. The internship provided the opportunity to learn about the BBT installation. BBT installation is very new in our country and it requires knowledge about electrical installation. The internship gives the opportunity to work as an executive. Working in practical field was challenging. The purpose of the intern ship is fully served by gaining experience in this particular field of engineering .
