Abstract

A new class of highly-miniaturized coaxial cavity-resonator-based filtennas is proposed alongside a monolithic integration approach using digital additive manufacturing. The proposed filtenna concept is based on the EM co-design of a coaxial cavity resonator and an annular slot antenna that exhibit the function of a radiating resonating node within a coupled-resonator-based bandpass filter (BPF). A stereolithography apparatus (SLA) monolithic integration concept is proposed for size compactness and reduced weight. For proof of concept validation purposes, a second-order filtenna was analyzed, manufactured, and tested. It exhibited second-order frequency-selective gain response with the following characteristics: center frequency: 4.75 GHz, fractional bandwidth: 7.4 %, realized gain: 4.4 dBi and radiation efficiency: 80%.
