This paper deals with the implementation of a compact frequency reconfigurable antenna in a challenging environment being embedded in a laptop. The antenna structure is designed to be restricted in a volume of 3.3 cm3 (70mm∗12mm∗4mm). The antenna structure was originally developed through EM simulations using CST Microwave Studio and later prototyped and tested in a Laptop mockup. The antenna structure...
This paper presents a miniaturized right hand circularly polarized antenna design for operation at the GPS frequency [1575 MHz]. This antenna structure utilizes a pair of planar Isolated Magnetic Dipole [IMD] antennas collocated on a square ground plane and fed 90 degrees out of phase to generate right hand circular polarization. The antenna design provides axial ratio of less than 1.5 dB at zenith.
The advent of 4G LTE has ushered in a growing demand for embedded antennas that can cover a wide range of frequency bands from 698 MHz to 2.69 GHz. A novel active antenna design is presented in this paper that is capable of covering a wide range of LTE bands while being constrained to a 1.8 cm3 volume. The antenna structure utilizes Ethertronics EtherChip 2.0 to add tunability to the antenna structure...
With the growing use of M2M [Machine to Machine] communication in the industry, it has become essential to have antennas in devices that cover a wide frequency range from 700MHz to 2700 MHz and work efficiently by being impedance matched under various environmental effects. This paper proposes a closed loop impedance matched antenna system solution to tackle this challenging issue. A novel and compact...
