The emergence of CubeSats/SmallSats began a miniaturization revolution in the satellite
domain nearly 20 years ago. Only a few people could have predicted their capabilities at the …

In this article, a dual-polarized frequency-reconfigurable mm-wave patch antenna array is
described. The design incorporates varactor diodes (VDs) symmetrically loaded onto the …

A compact filtering mechanism in the antenna system is required to avoid unwanted
incoming electromagnetic waves in the working frequency band. A circularly polarized (CP) …

A miniaturized second-order tunable filtenna using substrate-integrated waveguide (SIW)
technology is presented in this letter. The coupled-resonator theory for bandpass filter …

This article presents a novel superstrate-loaded frequency-agile cavity-backed slot antenna
(CBSA) and filtenna for X-band (8–12 GHz) applications. The antenna is designed by …

This paper investigates an angularly stable artificial magnetic conductor (AMC) loaded
circularly polarized (CP) antenna array and filter co-design for the K-band satellite …

The fifth generation (5G) mobile communication systems employ technologies such as
massive MIMO, millimeter-wave (mmWave), and ultra-dense networks to support higher …

A highly multifunctional antenna with multilinear polarizations (MLPs) and multibands (MBs)
is proposed, which can operate over four reconfigurable frequency bands, each band …

With the rapid development of next-generation technologies like Software-defined Radio
(SDR) and cognitive radio (CR), there is an ever-increasing demand for the next-generation …

In the pursuit of increasing data transmission rates, mobile communications have rapidly
evolved into the 5G era. With more and more frequency bands being specified and utilized …
