Directional 1900 MHZ Square Patch Ring Slot Microstrip Antenna for Wcdma

Abstract

Telecommunications systems especially WCDMA networks, require an antenna to convert electromagnetic energy in the air into electrical energy will be processed into the information signal. WCDMA (Wideband Code-Division Multiple Access) network works at a frequency of 1900 MHz with a complicated configuration antenna and has high-cost components. Directional 1900 MHz Square Patch Ring Slot Microstrip Antenna for WCDMA has been proposed. This is a novel technique in telecommunication configuration to make directional antenna use more proper and efficient component by using low cost and easy to find material at 1900 MHz frequency. This compact configuration consists of a single rectangular patch, a substrate, a ground plan and ring slot on the ground plane. This antenna produces an accurate frequency at 1900MHz with the value of-15.19 dB and gains 6.78 dBi at. The overall size of the proposed antenna is 55.7 mm times 49.2 mm with FR4 (Phenolic White Paper) with a dielectric constant value is 4.4.

2.4 GHz SQUARE RING PATCH WITH RING SLOT ANTENNA FOR SELF INJECTION LOCKED RADAR

“…Where Lp is the patch length and fr is the resonant frequency The 2.4 GHz Square Ring Patch with Ring Slot antenna design is finished by mathematics on the matter and matrix delivers from the literature [12] [13]. The product of the concept then simulated using the scheming software to specify the parameters of the Square Ring Patch with Ring Slot antenna.…”

“…shows the prototype of the Square Ring Patch with Ring Slot Antenna microstrip antenna for SIL Radar that has been manufactured. The ring patch on antenna faces is used to establish directional radiation to the front, high gain and optimum efficiency with not big and tight antenna dimension [13]. The overall Ring Patch with Ring Slot Antenna microstrip antenna size of the proposed antenna is 55.7 mm x 49.2mm…”
