| contents | This work introduces a novel, compact antenna design based on a lambda-6th suspended patch configuration that is particularly suited for small-size wireless sensor nodes. The proposed design meets key requirements such as compactness, omnidirectionality, robust source matching over a designated bandwidth, interference immunity, and low costs by evolving the conventional square patch antenna. With a footprint of only 20-by-20 mm, the antenna incorporates a grounded metal shield to both reduce its effective dimensions below one-half wavelength and mitigate interference from nearby circuitry. Simulation results, conducted on a cost-effective FR4 substrate, demonstrate a resonance at 2.45 GHz with a return loss of -32.5 dB and a bandwidth of 50 MHz (at the -10 dB level), making this design an attractive candidate for integration into densely populated wireless sensor networks. |
