A reconfigurable microstrip patch antenna with RF pin diode switches is implemented for dual band of 2.4 GHz and 5.6 GHz WLAN Software Defined Radio (SDR) applications. For the dual band SDR system, the use of a single antenna with a wide bandwidth to cover both of the bands can be limiting for low power level signal applications due to wideband noise as well as changing radiation pattern at di...

The compact rectangular microstrip antenna is realized by placing the shorting post or plate along the zero field line at the fundamental mode of the patch. The dual band antenna is realized by placing the stub on the edges of the patch. In this paper, first a compact shorted rectangular microstrip antenna is discussed. Further a dual band antenna realized by placing the stub on the opposite ed...

A novel design of Dual band pyramidal serrated microstrip patch antenna was designed and Simulational results are presented in this paper. Equal spaced serrated pyramidal shapes are etched on four sides of the patch and its performance characteristics are simulated using commercial software HFSS. The current model is resonating at dual band with moderate gain. Return loss, radiation patterns, i...

–The paper presents the good matching between simulated and measured results of dual band and broad band rectangular patch mircostrip antenna with T shaped slot (RPMATSS) for the WiMax Application. This antenna is designed on glass epoxy FR-4 substrate. The performance of this antenna is also compared with that of a simple rectangular patch antenna. The simulated results for this antenna are op...

This paper presents a novel compact dual-band and dual-polarized complementary split-ring resonator (CSRR)-fed substrate-integrated waveguide (SIW) cavity-backed fractal patch antenna for wireless energy harvesting and communication. The proposed antenna is composed of a Giuseppe Peano fractal radiation patch with a backed SIW cavity. To enhance the bandwidth and minimize the dimensions, the CS...

In the present paper notch loaded shorted microstrip patch antenna has been analysed using cavity model. The proposed antenna shows dual band operation which depends on notch dimensions as well as shorting wall. The frequency ratio is found to be 1.5278 for the notch loaded rectangular patch, while in notch loaded shorted patch, the frequency ratio varies from 2.9764 to 2.725 for increasing val...

The study of Microstrip patch antennas have made great progress in recent years. Compared with conventional antennas, Microstrip patch antennas have more advantages and better prospects. They are lighter in weight, low volume, low cost, low profile, smaller in dimension and ease of fabrication and conformity. Moreover, the Microstrip patch antennas can provide dual and circular polarizations, d...

In the present paper notch loaded shorted microstrip patch antenna has been analyzed using cavity model. The proposed antenna shows dual band operation which depends on notch dimensions as well as shorting pin. The frequency ratio is found to be 1.75 for the notch loaded circular patch antenna. The theoretical results are compared with IE3D simulation.

This paper introduces the design of a dual-band internal F-PIFA (Fractal Planar Inverted F-antenna) as a candidate for use in the dual band WLAN (wireless local area network) MIMO (multi-input multi-output) applications. At first, the 4th iteration Koch’s fractal geometry has been applied to the edges of the conventional rectangular patch structure to design a single compact antenna with a dual...
