Compact Tunable and Dual band Circular Microstrip Antenna for GSM and Bluetooth Applications

چکیده
A Circular Microstrip Antenna with slot cut in it for tunable and dual band operation has been presented. The existence of an electrically small slot along the feed axis or the perpendicular axis changes the resonant frequency of the patch leading to tunability. If both slots co-exist and are of comparable lengths, which equals to greater than half of the radius, dual frequency operation is obtained. A design has been proposed for obtaining dual band operation for GSM 1800/1900 Bluetooth 2450 MHz. Experiments have been performed to validate the theoretical results.

Multi Attribute Analysis of a Novel Compact UWB Antenna with Via-fed Elements for Dual Band Notch Function (RESEARCH NOTE)
A compact microstrip-fed antenna with dual notched bands is proposed. First, a simple basic configuration is presented for Ultra Wide Band (UWB) applications and then the dual band notched structure is extended from the UWB one. The basic structure of the UWB antenna consists of a simple square radiating patch and a ground plane with a wide square slot on back of the substrate. A semi-circle sh...

In this paper, we propose a new compact quasi-fractal shaped microstrip antenna that consists of a hexagonal patch as the main radiator and a complementary stacked patch as the parasitic element. The overall surface of the proposed quasi-fractal patch is about 55% lower than the conventional hexagonal patch. Using of stacked technique, the gain reduction of compression technique is almost compe...
متن کاملA Novel Compact Ultra-Wideband Antenna with Single and Double Band Rejection
Band-notch characteristic has been of great interest recently to overcome the electromagnetic interference of Ultra-wideband systems (UWB) with other existing ones. In this paper, we present a novel microstrip-fed antenna with band rejection property appropriate for UWB applications. Band-notch characteristic has been achieved by adding a rectangular resonant element to the ground section. A pr...
متن کاملModified 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...
