Abstract
Here, a simple frequency selective surface (FSS) is intuitively designed, and two such FSS are placed at right angle with each other, with a small predetermined air gap between them, to form a composite FSS structure, and a conical dielectric ring resonator (DRR) loaded monopole antenna is placed in between the two FSS. The DRR loaded monopole offers wide impedance bandwidth from 6 to 20 GHz, with a peak gain of 4 dBi. This composite FSS causes rejection of frequency band of nearly 2 GHz from anywhere in between 6 and 20 GHz, the wavelength of the center frequency of the rejected band being proportional to the dimension of the FSS and distance of the composite FSS from the antenna. Hence the composite FSS shows bandstop character, whereas it also causes 6–7 dB gain enhancement in its passband. The FSS structure is non complex, cost effective, and easy to fabricate.
