Abstract
A common design solution of wideband filtering antennas inspired by the synthesis of a flat-top gain curve is proposed by using mutual coupling effects. The realization of a frequency-varied flat-top gain curve based on specially designed subarrays is analyzed. Analysis results conclude a design process of generating filtering response based on shorting pins and parasitic structures. A single-layer rectangle patch array loaded with parasitic shorted patches is designed and analyzed for the validation. The proposed antenna possesses an impedance bandwidth of 4.95–6.05 GHz and a peak realized gain of 11.2 dBi. Besides, the design has its out-of-band rejection levels higher than 15 dB.
