Coupled microstrip line
WebAbstract—In this paper a novel rose leaf shape microstrip antenna with capacitively coupled rectangular fed is presented.Various shapes of capacitive coupled fed are compared and optimized by successive iterations of a computer-aided analysis.The Ansoft HFSS is employed for analysis at the frequency band of 4.3GHz–8.3GHz. The antenna is Webwidth-height ratio, W/h of the microstrip laminate. The term, η is the wave impedance in free space. In microstrip line configuration, the transmission line conductor of a typical N +1 section of coupled line filter takes the form shown in Fig. 2a-b. Fig. 2.
