“…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.

“…16 standard, has been evaluated by companies for last mile connectivity, which can reach a theoretical up to 30 mile radius coverage. The WiMAX forum has published three license spectrum profiles, namely the 2.5 GHz (2.495-2.69 GHz), 3.5 GHz (3.5-3.6 GHz) and 5.5 (5.25 -5.850GHz) varying from country to country [1][2][3][4][5][6][7]. Recently, the microstrip patch antenna has been introduced with the aim of improving performance and obtaining the multiband behavior.…”

In this paper a design of a new antenna with modified ground plane is validated for multiband applications. The proposed modified ground structure is incorporated with a patch antenna to boost the performance. The antenna's entire area is 59.5x47mm 2 and is printed on an FR-4 substrate and fed by a 50 Ohm microstrip line. This structure is validated in the GPS (1.56-1.58 GHz) band at 1.57 GHz, in the ISM (2.43-2.49 GHz) band at 2.45GHz and in the WiMAX (3.50-3.56 GHz) band at 3.53 GHz. These three frequency bands have good matching input impedance for, S11≤-10 dB. The antenna presents a good performance in terms of radiation pattern, and it is designed, optimized, and miniaturized by using CST-MW whose results are compared with other solvers HFSS and ADS. The results obtained by the use of the three EM solvers are in good agreement. After realization, we have tested and validated this antenna. The measurement results of the antenna present a good agreement with the numerical results. Keyword:GPS band ISM band Modified Ground Structure Multibande Antenna WiMAX band
