In this paper, a novel microstrip-fed compact antenna with triple band-notched characteristics is presented for ultrawideband (UWB) applications. The antenna consists of a circular radiating patch, a 50 Ω microstrip feed line, a partially slotted ground plane, and a pair of modified capacitance loaded loop (MCLL) resonators. The novel resonators are symmetrically located in the vicinity of the ...

Slotted Meander-Line Resonator (SMLR) is implemented by creating defect in the microstrip structure. This resonator is designed to block the surface current at the resonant frequency of the two patch antennas coupled along H-plane operating at 3.6 GHz. The proposed configuration provides an improvement in isolation by 10 dB (measured value) with a reduced edge-to-edge spacing of 7 mm (λ0/9). Th...

A Coplanar Waveguide Fed ultra wide band (UWB) slotted Hexagonal patch antenna which finds application in wireless communication is presented here. It was designed to operate in the UWB range ( 3.1GHz to 10.60GHz). The antenna presented here is designed on FR4 substrate with loss tangent δ=0.0025 and dielectric constant 4.4. The dimension of the proposed antenna is 34 X 29 X 1.6 mm. The fundame...

A band-removal property employing microwave frequencies using complementary split ring resonators (CSRRs) is applied to design a compact UWB antenna wishing for the rejection of some frequency band, which is meanwhile exercised by the existing wireless applications. The reported antenna comprises optimization of a circular radiating patch, in which slotted complementary SRRs are implanted. It i...

To suppress electromagnetic interference at 5.5-GHz WLAN (5.15–5.825 GHz) band operation, a novel ultra-wideband (UWB) design of a slotted twin-patch monopole antenna with a band-rejection characteristic is presented. The proposed antenna with a simple structure has a large impedance bandwidth, defined by 10-dB return loss, covering the range from 2.95 to 10.85GHz, and a tunable cutoff band fro...

A Slotted microstrip patch antenna for Ku band is designed and thoroughly simulated in this paper. The designed antenna is worked at Resonant frequency of 14.25 GHz in Ku band and that can be used in Satellite Communication for Satellite Tv, DBS services,satellite tracking etc. It is shown that the simulated results are in acceptable agreement. More importantly, it is also shown that the micros...
