First, this letter presents a novel meander square‐ring resonator (MSRR) and its stop‐band and slow‐wave effects are investigated. Served by the proposed MSRR, unwanted higher‐order 2nd and 3rd harmonics of power divider are effectively rejected benefiting from its stop‐band effect without any additional filter, and the physical length of quarter‐wavelength 70.7 ohm microstrip in power divider is halved utilizing its slow‐wave effect without decreasing the electrical length. Finally, power divider with area reduction by 42.6% is successfully obtained, compared with conventional design. © 2009 Wiley Periodicals, Inc.
