“…The return loss obtained for these antennas was comparable to that of antennas designed using PTFE and FR4 substrates, which are most commonly used in microstrip antenna fabrication. 24 CONCLUSIONS LDPE/TiO 2 and PS/TiO 2 composite systems show enhanced microwave permittivity, thermal conductivity, and thermal dimensional stability with increasing filler percentage. As the size of the filler particles was significantly less than the probing wavelength, the loss due to scattering was also less.…”

Low-density polyethylene (LDPE)/titania (TiO 2 ) and polystyrene (PS)/titania (TiO 2 ) composite systems have been developed as alternative substrates for microstrip patch antennas (MPA) for handheld devices. Morphological, thermal, and microwave characterizations of these composites have been conducted for different volume fractions of TiO 2 in the polymer matrix. The size of the titania particles was found to be of the order of 0.5 lm, and their distribution in the composite was quite uniform. Composite materials showed an improvement in thermal and microwave properties over the parent polymer. Verification of these composites as potential substrates for MPA was carried out by fabricating simple rectangular patch X-band antennas. Materials with optimized substrate properties were chosen to design the MPA. The patches were designed with 4% volume fraction TiO 2 in the LDPE composite system and 6% volume fraction TiO 2 in the PS composite system. Return loss of $18 dB was observed for both systems.

“…The circular microstrip patch antenna is one of the classical geometric shapes that normally used in communication systems to their advantage of easy to fabricate, simple, low profile, small in size, lighter in weight and low cost [1] - [4]. However, there is a limitation on its performance for a microstrip patch antenna in term of narrow bandwidth.…”

This paper presents the investigation based upon resonant circuit approach to characterize a single-, dual-and quadruple-mode microstrip patch antenna from the lowpass prototype lumped element. This theoretical method is used to determine the coupling value for quad mode antenna design in order to obtain maximum bandwidth. To validate this concept, the quad mode antenna based upon an equivalent circuit at centre frequency of 2 GHz is demonstrated and verified through simulation and measurement. Experimental results show good agreement with simulated results. This study also proposes a technique to integrate two dual-mode antennas based upon the multilayer approach. This study is useful for any microwave system design where the reduction of overall physical volume, weight and cost is very important as well as bandwidth improvement.Index Terms-resonant circuit, dual-, quadruple-mode, microstrip patch antenna.

“…For example, not much attention was paid towards the analysis of elliptical patch geometry perhaps due to involvement of elliptical coordinate systems and application of Mathieu's function in theoretical analysis [14,15]. Since circular polarization can be easily achieved with this structure hence in recent times several papers on elliptical patch antennas may be seen [16][17][18] …”

In this communication design and performance of a novel single-layer assembly of gap coupled elements in elliptical shape is proposed to achieve broadband performance with circular polarization. Out of five patches considered in this assembly, two pairs of patches having different patch areas are arranged close to an edge truncated elliptical patch. The central edge truncated elliptical patch is fed through inset feed arrangement and the other patches are parasitically gap coupled to the central patch. With such an arrangement, an improved impedance bandwidth of 1.58 GHz or 18.5% with respect to central frequency 8.5 GHz is achieved. Three resonant modes are excited with this arrangement giving improved bandwidth and gain in comparison to a conventional elliptical patch antenna with same semi-major and semi-minor axes. In the entire bandwidth, the simulated radiation patterns of proposed arrangement of patches are more or less identical in shape.
