PPT-Microstrip Patch Antenna

Dr Md Mostafizur Rahman Professor Department of Electronics and Communication Engineering ECE Khulna University of Engineering amp Technology KUET Antenna Theory Micro Strip In spacecraft or aircraft applications where size weight cost performance ease of installation and aerodynamic profile are constraints low profile antennas are required Micro . However extensive research has provided numerous approximate modelling techniques which are adequate for many design purposes The following are a collection of some of the more useful formulae for microstrip circuit design 1 EQUATIONS FOR MICROSTRIP H Chou Department of Engineering Cambridge University Cambridge CB3 0FA UK HT Chou Department of Communications Engineering Yuan Ze University ChungLi 320 Taiwan Abstract This paper presents an approach of a shaped re64258ector antenna synthesis usin CHALLAL 12 A AZRAR 1 and D VANHOENACKER JANVIER Dept of Electronic IGEE University of Boumerdes Boumerdes Algeria mchallalgmailcom ICTEAM Electrical Engineering Universit catholique de Louvain Louvain La Neuve Belgium mouloudchallaluclouvainbe Abst Octagonal MPA Feed line Feed line Feed layer with Ground Port 1 (b) (0,0) 2 F1 PORT 2 The geometry of the Octagonal MPA is illustrated in fig.1.
