The effect of the cavity on the antennas and the interaction of the two antennas are studied through experiments.
Our products amounted to 60% of Gionee antennas and we were their main supplier in 2005.
This makes the TEM horn antennas have good fidelity when radiating and receiving short time domain impulse antenna.
Air Force-funded researchers at HRL Laboratories in Malibu, Calif., are working on holographic impedance surfaces for antennas that will give aircraft improved aerodynamics.
Just as a radio antenna will resonate with and absorb certain radio waves, nanostructured optical antennas can resonate with and absorb visible and infrared light.
Pedersen had made them himself, with the help of an enormous array of antennas that can hurl several megawatts of radio waves into the upper atmosphere, creating brilliant light shows in the sky.
Some blame the design of the phone's radios and antennas.
This paper investigates the inverted L antennas mounted on a conducting concave surface.
The derived lower bound indicates the system performance is affected by the codebook size, transmit antennas and modulation.
The desired signal in the auxiliary antennas of guidance radar may cause Angle measurement error by using conventional adaptive sidelobe cancellation method.
We tend to ignore the fact that our cellular telephone doesn’t work like a landline phone; instead, it is actually a radio transceiver that might swap connections between a half-dozen different cellular base antennas in the course of a two-minute call. Knowing this doesn’t help us to understand how to use the phone.
The theoretical NSA values given by the standards are grounded on the assumption that transmit and receive antennas are infinitesimal dipole antennas which is inappropriate to measurements.
This had all the electrical properties that antennas need to function, but was much more flexible than its copper equivalent.
Stick one of the router's antennas through the mouth of the beer can and use a small piece of duct tape or blu-tack to keep it in place, then repeat the process for the other antenna.
In the background are the antennas of Strykers armored vehicle.
This paper expounds that errors of the array effect on the performance of the antennas by analyzed the performance of the phased array antennas and how to correct the errors.
The MIMO systems use multiple antennas at both the transmitter and receiver to transmit signal in the same frequency band at the same time can significantly increase the channel capacity.
In the paper, a novel open ring cancellation circuit is designed to improve isolation between antennas.
With President Obama among the crowd of 8, 111, the flight tower, which sailors call The Island, loomed above the court, itsradar antennas spinning, its satellites standing sentry.
Can you tell me if the four antennas have left Hong Kong?
The contract also included accessory equipment consisting of batteries, vehicle antennas, manpack antennas and mounts.
Equipment initially used to demonstrate this new capability has been refined so it requires two rather than three antennas, and details of this upgrade will be made public in a paper next month.
There are all kinds of antennas used in EMC test such as biconical antennas, log periodic antenna, helical antenna, ridged horn antenna and etc.
The Allen Telescope Array (mostly paid for by Paul Allen, co-founder of Microsoft) consists of 42 dish antennas, each six metres across, scattered across the countryside.
In the upper portion of the band, waves can be focused or collimated by dish antennas of modest size.
