Built in Bluetooth wireless transmission allows easy GPS sensitivity record on the go without the hassle of external USB connections and wire cable anytime, anywhere. The mobile phone under test of far-field range testing has been the plan at the Cellular Telecommunications & Internet Association (CTIA) certification program test requirements for performing receiver performance measurement.
In this paper, we present vector modulation technology in millimeter-wave active phased array antenna (APPA) as a replacement of conventional digital phase shifter and digital attenuator. Both a 1×8 Ka-Band active phased sub-array antenna and an 8×8 Ka-Band active phased array antenna are developed to verify vector modulation technology in millimeter-wave active phased array antenna, respectively...
In this paper suggestion FPC for antenna design not only easy to control the antenna pattern on desired direction and radiation magnitude but also effective and quickly solved the complex tuning parameters of antenna application. Flexible printer circuit (FPC) board serves planar wireless antenna design. Effectively to supersede the antenna based on the traditional fixed printer circuit board (PCB)...
A high performance wire monopole antenna fabricated using two meander wires as radiator is presented. A prototype of the proposed monopole antenna with a compact area size of 24mm × 10mm is implemented, and the multi-band WLAN antenna shows a wide operating bandwidth of about 637MHz and 1000MHz for low band and high band, bandwidth, making it easy to cover the IEEE 802.11a, IEEE 802.11b, IEEE 802...
Artificial materials of periodic dielectrics exhibiting an electromagnetic band-gap (EBG) performance have been proposed and applied antenna co-design and measurement. The artificial dielectric material (ADM) can enhance antenna performance. The artificial defected dielectric material has useful characteristics of harmonic rejection, band suppression and surface wave suppression. And then the design...

The semi-rigid cable for microwave band as a feeding network structure that effectively excited tapered TEM horn antenna geometry is proposed. The semi-rigid cable to parallel waveguide transition then to fed tapered TEM horn antenna. The designed tapered TEM horn antenna has the merits such as wideband, simple feeding network, low profile compact size with fairly good antenna performances such as...
