Abstract

This paper presents the design and realisation of a compact reconfigurable quad-/dual-band microwave antenna, which has been implemented based on a novel quad-mode slotline resonator (SLR). The coplanar waveguide (CPW) feeding structure has also been designed in detail in order to be able to optionally function under both the weakly-or strongly-coupling conditions. Under the weakly-coupling condition, the antenna has four narrow operating bands relating to the four resonant modes, while under the strongly-coupling condition, another resonance arises. As a result, a dual-band antenna is produced with a very wide second band. The fabricated antenna has then been thoroughly measured under both the intended conditions, which show good agreement with the conducted simulations.
