Double exponentially tapered slot antenna (DETSA) on liquid crystal polymer (LCP) for UWB applications

A DETSA on organic material (LCP), suitable for packaging and integration with other components, is introduced and proposed for the UWB range. The measurements agree fairly well with the simulation and this antenna is proved to perform well in the whole UWB range. Return loss below -10 dB is measured for the whole frequency range of operation. The antenna performs with high gain starting from 7 dB for low frequencies and up to 12 dB for the higher frequencies. The antenna on LCP is conformal, can be easily fabricated with relatively low cost and is a good candidate for a number of UWB applications.
