In this paper, the authors analyze how the resonant modes of circular microstrip patch resonators are affected by the presence of circular apertures in the ground plane located under the patches. A rigorous full-wave analysis in the Hankel transform domain (HTD) is carried out in order to obtain the resonant frequencies, quality factors, and radiation patterns of the circular microstrip patch r...

This paper presents triple band notched ultra wide band (UWB) monopole antenna with overall size of 36 × 32 mm fed by microstrip transmission line. In order to achieve a good impedance matching from 2.7 GHz to 13.4 GHz, a tapered transition between the rectangular patch and the feeding line is utilized. The three notched frequency bands are accomplished by a defected microstrip structure (DMS) ...

In this paper, a circular microstrip antenna for stress evaluation is studied. This kind of microstrip sensor can be utilized in structural health monitoring systems. Reflection coefficient S11 is measured to determine deformation/strain value. The proposed sensor is adhesively connected to the studied sample. Applied strain causes a change in patch geometry and influences current distribution ...

This paper presents several microstrip patch antennas, for reception at X band. From passive and active single patches to active arrays, design, fabrication, integration and test are addressed.

The microstrip antenna finds applications in varied and upcoming technologies because it offers low profile, narrow bandwidth, high gain, and compact antenna element. The microstrip antenna have biggest disadvantage of narrow bandwidth and poor impedance matching. To make microstrip antenna compatible with commercial applications, the bandwidth enhancement and impedance matching of such antenna...

Antenna is a means for radiating or receiving or transmitting energy an antenna is used in an advanced wireless system is usually required to optimize the radiation energy in same direction and suppress it in others. A microstrip patch antenna, also referred to as patch antenna is a narrowband, widebeam antenna fabricated by etching the antenna element patch in metal trace bonded to an insulati...

Genetic Algorithm combined with Finite Element software is applied to design a single-patch broadband microstrip patch antenna in this paper. The optimization procedure is also included. The broad-band character is realized by taking out some parts of the ordinary patch antenna. The reliability and efficiency of this method are proved by comparing the antenna proposed in this paper to un-optimi...
