A miniaturized and self-packaged Gysel power divider with embedded metamaterials in SISL platform

Abstract

This paper presents a self-packaged Gysel power divider (PD) with embedded metamaterials in substrate integrated suspended Line (SISL) platform. Metamaterials are formed by a periodic arrangement of I-shaped electrical resonators that can produce high dielectric constants and are encapsulated in the multi-layer SISL structure to reduce the circuit size. Fabricated by using a standard printed circuit board (PCB) process, the proposed Gysel PD is self-packaged. The structure of the meandering line introduced in the layout of PD can be downsized. The designed PD with embedded metamaterials operates from 3.3 to 3.6 GHz with a bandwidth of 14.8% for S 11 < −20 dB. Compared with the case where metamaterials are not embedded, the circuit area is reduced by about 61%.

“…The filled dielectric block can also be used as a resonator for filter design. Figure 57 shows an SISL-based du-al-band dielectric resonator filter (DRF) [33]. The DRF was fed by a strip ring and achieved degenerate mode coupling through a coupling ring.…”

A wideband and self-packaged D-CRLH diplexer based on substrate-integrated suspended line

“…In the experiments and practical system application, the RF device made of a microstrip line needs to be packaged with the metal box, and the loss of the packaged microstrip line device increases. To overcome these shortcomings, many efficient SISL devices are proposed [20,21,22,23,24,25,26,27]. By using SISL, the electromagnetic shielding performance of RF devices is achieved.…”
