Cost-effective Single-Layer Metallic Lens Antenna with High Aperture Efficiency
[EN] This paper presents a novel millimeter-wave high-gain single-layer lens antenna design that
features a metallic ring as its foundational element. Leveraging characteristic modes analysis, the shape
of the structure is systematically optimized. The resulting planar antenna exhibits outstanding radiation
performance alongside its simplicity, achieving a gain exceeding 20 dBi at 20.50 GHz, and an aperture
efficiency of 63 %). These exceptional performance characteristics make it ideal for applications in 5G
and 6G systems. Additionally, the use of a cost-effective manufacturing process increases its potential for
widespread adoption in future communication technologies.This work was supported in part by the Spanish Ministry of Science and Innovation (Ministerio de Ciencia e Innovacion) under Project

On-Ground Small LTCC Chip Antenna and its Placement on IoT Devices
[EN] A low-profile on-ground chip antenna is presented to
be installed in size-limited devices for 868 MHz Internet of Things
applications. The antenna presents a size of 0.064 × 0.045 ×
0.007¿3
0, has been fabricated in low-temperature cofired ceramic
technology, and is meant to be placed on a ground plane without a
clearance area required. A study regarding matching and total efficiency is performed by analyzing the antenna in different positions
of a variable-size ground plane with the use of characteristic modes
analysis and the correlation between modal and total radiated
fields. The analysis demonstrates through the correlation which are
the excited modes of the ground plane and, consequently, which is
the best position for the antenna. Results show frequency stability
and a total efficiency difference of up to 8.8 dB between different
positions.This work
