A Ka-band CPW-Slot-Couple (CSC) fed microstrip antenna with enhanced bandwidth and gain is presented in this paper. To simplify the feed network, matching slots are designed at end of CPW. Consequently, patch a low profile, which has size 7.2 × 32.6 0.508 mm3. Characteristic mode analysis (CMA) applied to illustrate principle enhancement band form characteristic point view. slot based on induct...

The fractal antennas that have the multiband operation due to the self-similar property in fractal geometry, which plays a key role to create a fractal circular monopole patch antenna. The other important property that is, Space-filling property which actually determines the reduction in the size of the antenna. This property adds more electrical length in less volume which reduces the size of ...

In this paper, a miniaturized coplanar waveguide fed (CPW-fed) tapered slot antenna (TSA) is introduced for breast cancer detection. Here, a modified CPW to slot-line transition structure with an air-bridge is employed to broaden the transition bandwidth and increase the radiation efficiency. Through these applied modifications, negative features of the original TSA (limitation of transition) a...

This paper presents the design of a wheel shaped multiband fractal Antenna. This Fractal antenna has been designed on substrate εr = 4.3 and thickness h = 1.53 mm. This new antenna has been fed with CPW – Fed. The antenna exhibits the multiband resonances due to selfsimilarity in antenna structure. The experimental results indicate that resonant frequencies occur at 1.34 GHz, 2.575 GHz, 4.22 GH...

In recent years, advances in material science for high-frequency electronics have generated novel materials that offer superior performance. Additive manufacturing (AM) has expanded the frontiers of microwave going beyond flat geometries and unique properties such as graded permittivity materials. Accurate electromagnetic (EM) characterization AM remains challenging given printing volume constr...

After the release of the unlicensed Ultra Wideband (UWB) spectrum 3.1 GHz to 10.6 GHz for the commercial purposes by the Federal Communications Commission (FCC), industries and academia pay much attention due to its properties of excellent immunity to multi-path interference, high secured data rate, low power consumption, and simple configuration. The feasible UWB antenna design face some chall...

This paper presents a design of triangular wide slot antenna with same shaped patch which is fed by CPW. Patch is working as a radiating element and wide slot working as a ground. Detail simulation is conducted to understand its behaviour and optimize for broad band operation. The results are analysed and discussed in terms of return loss, VSWR, Gain, current distribution etc. The result shows ...
