“…The simulation results of the basic antenna were obtained via HFSS simulator and supported by CST one. They are summarized in table 1 and show that the antenna is well adapted at 2.45GHz [20]. The radiation pattern of this antenna has a directional behavior, and the ratio of gain and directivity gives an efficiency of 42,62% by HFSS and 37,52% by CST.…”

This work involves two technics of MPA (Micro-strip Patch Antenna) radiation characteristics enhancement, firstly by the design of a 1*2 array antenna based on two slotted ones to enhance the gain and the directivity, secondly by the design of the same antenna with modified ground plan (DGS technic: Defected Ground structure). The 1*2 array antenna is feed by a 50-Ohm micro-strip line, set on an Epoxy FR-4 substrate, and designed to resonate at 2,45GHz frequency. Besides, simulation results of this array were performed by HFSS simulator and validated by CST, they were focused on adaptation characteristics (S11, VSWR and bandwidth) and far field radiation characteristics (Gain, Directivity and Radiation Pattern). The final proposed antenna can be used in narrowband indoor positioning application for RFID readers, using a fixedreader-scheme.

“…The RFID antennas must be designed on small size and light weight structures. One of the techniques used to design a miniature antenna is the use of the slots technique; this technique is based in the use of certain approaches to manipulate the current distribution of the structure to change its resonant frequency [9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26].…”

This work presents a miniature microstrip antenna at 2.45 GHz by using the slots technique. This microstrip antenna is fed by a CPW technique and designed for RFID reader system on FR4 substrate. A size reduction equal to 66.6% has been obtained compared to the conventional rectangular microstrip antenna. The total area of the final circuit is 19x31 mm 2 . The validated antenna has good matching input impedance with a stable radiation pattern, a loss return of -40 dB, and a gain of 1.78 dBi, a prototype of the proposed antenna has been fabricated and measured.
