This paper proposes a new structure based on substrate integrated defected ground structure (SIDGS), and uses this structure to construct a compact triplexer with narrow bandwidth. Compared with the previous literatures related to the triplexer, the triplexer formed by this structure has a smaller size. In addition, the structure has good scalability and can be composed of any number of multiplexers without worrying about the coupling between the slots, which has favorable design flexibility. Moreover, the method of designing a multiplexer using this structure is also given, simulated, fabricated, and measured to prove the method's effectiveness.

“…Several techniques are efficiently combined in this work to achieve the wideband requirements, which includes increasing substrate thickness, overlapping multiple resonances, the addition of slots, parasitic patches, and stepped‐notch structures . This process is performed systematically, and is explained as follows: Firstly, two layers of felt substrate is used instead of one, resulting in an overall thickness of 6 mm This is followed by implementing the multi‐resonance overlapping technique, performed by introducing two sub‐radiators in the form of rectangular patches.…”

A wideband microstrip-based wearable antenna with a fractional bandwidth of 51% is designed using textile materials for wearable applications. The antenna operates between 2 and 3 GHz with low back-radiation to ensure minimum coupling to the body and reduced electromagnetic power absorption in the human tissue. The behavior microstrip antenna topology, which is narrowband in nature, is altered via the combinations of various broadbanding techniques, while maintaining the existence of the full ground plane backing. This ensures that the antenna radiation is directed outward form the body to efficiently propagate wireless signals toward other off-body nodes and base stations. Simulation and measurement results indicated that the use of this microstrip topology with multiple broadbanding techniques is capable of reducing the back lobe, resulting in a front-to-back ratio of about 17 dB and a 3.5 dBi of average gain.
