V‐band dual‐polarised dielectric resonator antenna with bondwire feeding structures

Abstract

In this Letter, a V-band chip-level dual-polarised dielectric resonator antenna implemented by using bondwires and silicon-based integrated passive device technology is proposed. The square-shaped resonator is fed by two bondwire coupling structures which excite two degenerate modes orthogonal to each other. The resonance of bondwire itself is also found to enhance the antenna bandwidth to cover the 60 GHz band. Reasonable agreement between the simulation and the measurement is obtained. The measured antenna bandwidth is from 52.8 to 65 GHz. The measured isolation is better than 20 dB at frequencies of interest. The measured antenna gain is 4.5 dBi at 60 GHz. The proposed design can provide further applications for circularly polarised systems.

Design and its state‐of‐the‐art of different shaped dielectric resonator antennas at millimeter‐wave frequency band

“…DRA is a suitable candidate for mm‐wave communication when it is compared with the conventional metallic patch antenna . Due to its extensive characteristics, that is, absence of metallic losses with the presence of DR, makes DRA, suitable candidate for mm‐wave applications.…”

“…This is mainly attributed to the fact that DRAs do not suffer from conduction losses and characterize by high radiation efficiency, when the feed is excited properly. For bringing a new horizon, an overview of basic shapes DRAs and a complete state‐of‐the‐art for mm‐wave DRAs are presented, as a comparative focus. Then, a working methodology in the form of design, simulation, and analysis of basic shaped DRAs at 60 GHz mm‐wave frequency band are reported.…”

Stacked dielectric patch resonator antenna with wide bandwidth and flat gain

“…Dielectric resonator antenna (DRA) has been widely used in modern wireless communication systems, owing to its merits of low loss (especially in millimetre‐wave applications) and high design flexibility in three‐dimensional geometry and material permittivity [1, 2].…”

Wideband low‐profile dielectric resonator antenna with a lattice structure

“…Another method of drilling perforations on the DRAs can lower down its Q factors, thus improving the bandwidths [6]. It is also possible to enhance the antenna bandwidth by using new feeding structure [7] or modifying DR geometry [8].…”

“…To meet the pressing demands of compact, wideband and high gain antennas for modern communication systems, various DRAs have been investigated [2][3][4][5][6][7][8][9][10][11]. In [2,3], a novel technique of cutting slots on the ground plane provides compact DRAs with wide bandwidths.…”
