A CPW rectangular-ring antenna over an Artificial Magnetic Conductor (AMC) is presented in this work. The AMC is designed as a dual-band structure having an array of unit cells and operates at 2.45GHz and 5.20 GHz. A CPW antenna uses this dual-band AMC structures as a back-plane. Performance comparison is carried out with and without the incorporation of AMC. The simulated and measured results show...
A new microstrip dual-band bandpass filter using folded coupled lines is designed and fabricated in this paper. The proposed filter exhibits two center frequencies at 2.6 GHz and 5.48 GHz with the corresponding fractional bandwidth of 23% and 11.8% respectively. The filter demonstrates good performance in terms of low insertion loss and high return loss at the lower and upper passband. The measurement...
This paper proposes a new design approach of a hexagonal fractal ring patch antenna for dual-band applications. The proposed antenna operates at two resonant frequency bands to cover 2.45-GHz WiFi and 3.5-GHz WiMax applications. To achieve dual-band operation, a first-iterative fractal-ring radiating patch is printed on a substrate layer coupled with another identical fractal ring printed in the other...
In this work, a dual band Microstrip patch implantable antenna for biomedical applications has been presented to operate in both Medical Implant Communications Service (MICS) with a range of 402–405 MHz and 2.4–2.5 GHz band chosen among the Industrial Scientific and Medical (ISM). A rectangular antenna has been first simulated to operate in MICS band with dimensions of 179.7 × 228.3 × 1.63 mm, then,...
