Abstract
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.
