Performance Analysis of Rectangular Patch Antenna for Different Substrate Heights

چکیده
Height of the dielectric substrate material for a microstrip patch antenna is utterly important in terms of controlling bandwidth as well as surface wave. In this paper we have presented a comparative study of effect of height in the performance parameters of Rectangular Shaped Microstrip Patch antenna. The antennas were simulated for purpose of the application of wireless LAN for resonance frequency 2.45GHz. Five antennas with different heights were designed using same dielectric substrate material with relative permittivity of 2.84 for the analysis of their performances. Coaxial Probe-feed methods are used for feeding techniques. This paper along with the comparison of performance parameters like VSWR, Reflection coefficient, Bandwidth, Impedance, Mismatch loss, Directivity, Gain and Field, also presents the effect of substrate height in design parameters like width, length, feed point location, ground dimension for each patch antenna. This study was carried out by using FEKO, Electromagnetic solver software which uses Method of Moments (MoM) technique.

Modified Rectangular Patch Antenna Loaded With Multiple C Slots for Multiple Applications
A new multiple C-slotted microstrip patch antenna is proposed in the present study. A patch antenna is a wide-beam narrowband antenna. The microstrip patch antenna consists of a very thin metallic strip (patch) placed a small fraction of a wavelength above a ground plane. The patch can be designed in any possible shape and normally made of conducting materials such as copper or gold. This study...

In this paper a microstrip antenna on a suspended substrate with capacitive feed is presented. capacitive feed is created by a slot within the rectangular patch around the feed point. The proposed antenna exhibits a much higher impedance bandwidth of about 47% (S11 < −10 dB). Effects of key design parameters such as the air gap between the substrate and the ground plane, the gap width between r...
