This article proposes a planar dual-band slot array antenna with high-gain operation for LTE / WiMAX access point. The impedance bandwidths, determined from VSWR 2.0, can reach about 18.3 / 14.6 % (475 / 510 MHz) for the 2.6 / 3.5 GHz operating bands, respectively, which is covering the bandwidth specification for LTE (2.5 ~ 2.7 GHz) and WiMAX (3.3 ~ 3.7 GHz) system. The proposed slot array antenna also provides maximum peak antenna gains and efficiencies of 13.9 / 14.1 dBi and 86.5 / 73.5 % across 2.6 / 3.5 GHz bands, respectively. Index Terms -LTE, WiMAX, Slot array antenna.

“…The proposed slot array is composed of 2 × 2 slot elements arranged symmetrically with the distance of L d between the slot elements. In this study, the single rectangular slot element with the dimension of L 1 × W 1 is simpler than those of slot antenna designs with the parasitic strips [ 3–6]. Then, the slit with the dimension of L 2 × W 2 is insetted into the center of the longer side of the rectangular slot fed by the 50‐Ω microstrip line.…”

“…So far, several planar antennas with a function of multiband operation for use in a GPS (global position system)/WiMAX (worldwide interoperability for microwave access)/WLAN (wireless local area network) dual-, triple-, or even multinetwork system have been proposed. These designs include the monopole antennas [1][2][3], slot antennas [4,5], strip-typed antenna [6,7], fractal-shaped antenna [8], and loop antenna [9]. However, most of these proposed designs are either with a large size owing to the most use of a big ground or with a complex structure to thus degrade their availabilities for practical application.…”

In this article, we have proposed an accurate calibration method for measuring photodetector wideband response with optical heterodyne measurement technique. The experimental result ranging from 0 to 48.65 GHz indicates that the proposed calibration method can effectively remove the errors introduced by extra fixture as well as laser output fluctuations. Good agreement between the calibrated frequency response and the data provided by the manufacturer has been achieved. The proposed method can improve the accuracy for optical heterodyne measurement technique and reduce the requirements in both laser output stabilities and fixture frequency performance, which is suitable to characterize the photodetector frequency response in an ultrawide frequency range.
