“…Since WiMAX has three allocated frequency bands called low band (2.5 GHz to 2.8 GHz), middle band (3.2 GHz to 3.8 GHz), and high band (5.2 GHz to 5.8 GHz), the proposed antenna is also applicable to WiMAX. The impedance bandwidth in percentage is 16.47% which is far higher than that of [4] who compared double rectangular patch with 4 bridges for 2.4GHz and 5.5GHz WLAN applications.…”

“…To overcome this problem and for the antenna to work within a stipulated band, a number of methods and structures have recently been proposed. Mention can be made of wideband aperture coupled microstrip array antennas [2], U-slot with proposed π-shaped stub [3], double rectangular patch with bridges [4], stacked layered structures [5], resonator antennas with capacitive coupled parasitic patch element [6], circular edge truncation [7]. This paper presents a wideband 2 x 2 rectangular slot microstrip antenna which covers the WLAN band.…”

This paper presents the design of a 2 x 2 microstrip array antenna suitable for wireless applications. The proposed antenna comprises of 4 rectangular patches where diagonal patches have the same length and width. A larger bandwidth and the desired resonant frequency are achieved because of a reduction in the quality factor (Q) of the patch resonator, which is due to less energy being stored beneath the patch due to the rectangular arrangement of the slots. The characterization results of return loss, gain, and radiation pattern are presented consecutively. From the results, the simulated impedance bandwidth defined for S11<-10dB reaches 1850MHz (4.69-6.54GHz) representing 16.47%.

En este trabajo se diseñó e implementó un arreglo de antenas con acoplamiento por microtira, con base en dos antenas rectangulares con cortes en las esquinas, diseñadas para operar a 2.4 GHz y a 5.8 GHz, dos rangos de frecuencia considerados entre los principales para aplicaciones de red de área local (LAN). De acuerdo con los resultados obtenidos en las simulaciones, la ganancia obtenida a 2.4 GHz es conveniente para interiores. En las pruebas prácticas se mostró que la influencia de la arquitectura, así como la posición de las antenas, es determinante en la recepción de la señal. Al comparar el desempeño de los prototipos con el de la antena comercial del ruteador utilizado, se obtuvieron mejoras en la recepción en la mayoría de los lugares analizados en el edificio de CIICAp. Además, el arreglo fue probado como antena de reemplazo en un teléfono inalámbrico, logrando un alcance de hasta 70 m en línea de mira. Las tolerancias del proceso de fabricación producen pequeños desfasamientos en las frecuencias de resonancia, mismos que pueden apreciarse en las pruebas de transmisión-recepción.

“…Two concentric rings are made on opposite sides of substrate which gives axial ratio bandwidth of antenna greater than 2%. Similarly dual band antennas are also designed for wireless local area network (WLAN) applications which use two rectangular patches with 4 bridges [2]. Also dual band antennas can be used for body worn applications in which specific absorption rate is an important criterion for wireless devices because portable wireless devices must meet various SAR (specific absorption rate) regulatory standards to minimize hazards to human health due to electromagnetic radiations emitted by wireless antennas [3].…”

In this paper, the performance of two dual-band printed microstrip-fed antennas is investigated, which have circular and hexagonal geometrical shapes. The hexagonal antenna shows the centre frequencies 1.6GHz and 3.8GHz and the circular antenna operates on 1.6GHz and 4GHz. These dual band antennas show the good simulated return loss and radiation characteristics. The proposed antenna designs are simulated on electromagnetic (EM) simulation software using FR-4 substrate with dielectric constant of 4.4 and thickness of 1.6 millimeter(mm). The proposed antennas have compact structures, the total size is 60×64 mm 2 and fed with 50 microstrip line by optimizing the width of partial ground. With the design, the return loss is lower than -10dB. A single rectangular slot is cut to obtain dual band operation. The proposed antenna is easy to integrate with microwave circuitry for low manufacturing cost. The antenna structure is flat, and its design is simple and straightforward. These antennas can be used in wireless communication.
