Abstract
Conical beam concentric array radial slot line antennas (RSLA) have been fabricated for the 60 GHz band. A PTFE substrate with copper foils is used. The coaxial feeder has been modified to improve the reflection. The measured reflection has revealed that the -15 dB bandwidth is about 500 MHz around the design frequency. The bandwidth of the gain has also improved because of the feeder modification.
