This paper presents a single-layer compact antenna with capability of realizing dual-sense circularly polarized (CP) radiation at two distinct frequency bands. The design employs multiple truncated-corner patches of different sizes operating in their fundamental modes, which are proximity-coupled through a probe-fed microstrip line. This configuration enables a single-layer structure, compact footprint, and flexible frequency-ratio tuning. This distinguishes the proposed design from the other related works, which are commonly multi-layer and large size due to the utilization of stack configuration or higher-order mode. Validation demonstrates that the proposed antenna exhibits dual-band operation at 5.2 and 6.5 GHz, with the operating bandwidths of 1.6% and 1.8%. Over these bands, the broadside gain values are higher than 6.0 dBi and peak at 6.5 dBi.

In alkenes, spin information is communicated via σ–π overlap, as seen in allylic (four-bond) and homoallylic (five-bond) couplings. These coupling interactions are stronger when the σ bond is parallel to the alkene π orbitals.
