The next generation of wireless communications is the horizon, and the telecoms world is waiting to see exactly at which frequencies 5G will be implemented. Despite some unknowns and technological challenges, it is increasingly becoming clear that the millimeter-wave will be a key enabler for 5G by allocating more bandwidth to deliver faster, higher-quality video, and multimedia content and services...
This paper proposes a Ka-band aperture-coupled microstrip patch antenna (ACMPA) based on low temperature co-fired ceramic (LTCC) technology for circular polarization (CP) at 29 GHz. The antenna consists of an aperture coupled patch with stacked parasitic strips (SPS). The CP is produced by cutting the patch and the parasitic strips. The antenna provides an impedance bandwidth of 1.2 GHz from 28 GHz...
In this paper, a novel method to enhance axial ratio bandwidth of circularly polarized (CP) patch antenna using artificial magnetic conductor (AMC) structures with LTCC technology at Ka-band is proposed. In order to improve the axial ratio bandwidth, the traditional PEC plane is replaced by an AMC plane. The AMC is composed of periodic square unit cells with truncated opposite corners. The AMC structure...
