A single feed, wide-band, stacked microstrip patch antenna for wireless communication system is presented in this paper. The proposed antenna consists of circular stacked patches over a slotted ground plane. The characteristics of the designed structure are investigated by using FEM based electromagnetic solver, HFSS. For the optimization analysis of the antenna design, HFSS's optometric analysis is used.

In this article, a dual band stacked micostrip antenna array is presented for wireless local area network. The antenna is designed and simulated using CST MWSv’14. Stacking of the patches is done to achieve dual band. Further resonant slots are cut on the patch to achieve greater bandwidth. The antenna uses aperture coupled feed with defected ground structure on reduced ground. The antenna is fabricated on FR4 substrate with a dielectric constant of 4.4. The simulated antenna shows a bandwidth of 228.3 MHz from 3.63 to 3.86 GHz and 232 MHz from 5.15 to 5.38 GHz. The simulated gain and envelope correlation coefficient was found to be 6.11 dB and 0.14. The testing of the prototype antenna (to measure S11) is done using vector network analyser. The measured results are matching to the simulated ones. The simulated and the measured results are presented in the article. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:648–654, 2017

This article presents a compact quadrilateral patch antenna design for cognitive radio system having dimensions of 50 × 50 × 1.6 mm3. The proposed antenna is designed with a triangular shape slot structure and quadrilateral patch with two step feedline on the either side of the FR4 substrate which is capable of switching for twelve different bands of frequency. The frequency range varies from 2.46 to 3.90 GHz, with a relative impedance bandwidth of around 45%. To achieve frequency agility six PIN diodes are used to vary the length of higher inclined arms of the slot. In the proposed approach, incorporation of biasing circuit into the ground plane reduces the parasitic effect, which improves the performance of the antenna. Moreover, the robustness of the proposed design is demonstrated in terms of reduction of antenna size, a number of frequency state, frequency ratio and number of PIN diodes used for frequency agility. The simulated and measured results for reflection coefficient, radiation pattern, relative bandwidth, gain, and efficiency are found to be in good agreement with each other.
