Abstract/Summary: | |
This thesis describes two major research topics: (i) the design of an UWB LHCP low-profile microstrip antenna of Archimedean spiral version; (ii) Modification of the SAC of the Florida Atlantic University's EMI R&D Laboratory to a FAC to perform the required antenna characterizations for the designed UWB antenna.; The microstrip spiral antenna is designed to operate in a traveling wave mode. It is constructed on a typical FR4 substrate and is center-fed through an SMA surface-mount connector. An RF chip-resistor located at the outer edge provides impedance matching. The UWB frequency performance of this antenna is among the widest reported in the microstrip antenna literature.; The second study refers to a methodology to modify the EMC listed SAC to emulate a FAC. Several pyramidal RF absorbing cones are strategically placed on the reflecting ground surface. The validation between the frequency range 300 MHz to 1 GHz is investigated. |
