Another notable example of multiband array is presented in [ 65 ]. In the study presented in [ 19 ], a switchable Vivaldi antenna has been demonstrated to provide either a narrow- or wideband frequency response.

A comparative analysis of various reconfigurable and multiband antenna concepts is presented. In order to satisfy the requirements for the advanced systems used in modern wireless and radar applications, different multiband and reconfigurable antennas have been proposed and investigated in the past years. In this paper, these design concepts have been classified into three basic approaches: Examples of each design approach are discussed along with their inherent benefits and challenges.
Traditionally wireless systems are designed for single predefined mission. Therefore, the antennas of these systems also possess some fixed parameters such as frequency band, radiation pattern, polarization, and gain. Recently reconfigurable antennas RAs have gain tremendous research interest for many different applications, for example, cellular radio system, radar system, satellite communication, airplane, and unmanned airborne vehicle UAV radar, smart weapon protection.
In mobile and satellite communications, reconfigurable antennas are useful to support a large number of standards e. On the other hand, in radar applications, reconfigurability at antenna level is often needed for multifunctional operation. This feature is achieved by utilizing antenna array systems that can be quickly adapted according to the mission. Therefore, a control over operating frequency, beam pointing direction, polarization, antenna gain, and so forth is required.

In reality, the government's own research showed that the risk of getting AIDS from one act of heterosexual intercourse was less than the chance of getting hit by lightening.

DEC External Examiner: Moreover, a new semi-ring monopole antenna with band-notched function is developed by adding four L-shaped slots in the radiating plates. In chapter 3, a new compact and multilayer UWB planar antenna is designed using the low-temperature co-fired ceramics LTCC technology, which gives the possibility of integrating RF circuits and antennas in a single substrate.
For the new automatic physical augmentation with tuning method, all series augmentation elements are transformed into their parallel equivalents, which reduced the preliminary analysis of the circuit to decide the augmentation type. Tuning is treated as a special case of augmentation by allowing negative valued element augmentation in some circumstances.
The proposed method has been validated for modeling a spiral inductor and an MIM capacitor in a wide bandwidth. Further, the new method has been successfully applied to extract the equivalent circuits for two UWB antennas.
A new wideband planar circularly polarized helical antenna array has been designed and realized in LTCC for the first time. Moreover, a GHz wideband LTCC aperture-coupled truncated-corner circularly polarized patch antenna with a sequential rotation feeding scheme is proposed and further integrated with a dB LNA to form a compact active receiving antenna.
The low loss transition structures are optimized and the bond wire packaging technology with a T-network compensation are studied and used to improve the performance of the GHz chip-package interconnection. The fabricated active antenna prototype demonstrated its wide impedance bandwidth, circularly polarized characteristic and enhanced receiving power. With the growing requirements on wireless communication, there is plenty of room for future extension of antenna design.

Congo Bongo is a really fresh 20 line slot machine that offer online casino players a jungle adventure with amazing cash and bonus prizes. The popular slot machine bird, - the Tucan, is used as the Congo Bongo slot machine scatter symbol that reward lucky players with scatter bonus prizes and the slots 20 free spin bonus feature where all prizes doubled.
Create a free InterCasino account and play Congo Bongo today. Images related to online casinos and slotmachines are used with permission and are copyrighted by their respective owners. The Congo Bongo free spin bonus feature is awarded when three or more of the Scattered Tucan symbols appear anywhere on the game reels.
This slot machine screenshot shows the feature trigger with a Tucan scatter symbol on the 2nd, 3rd and 5th slot machine reel. The bonus trigger result in a scatter bonus prize of 5 times the total slot machine wager and start the 20 free spin bonus feature with all prizes doubled. The Congo Bongo slot machine design changes a little during the free spin bonus feature. As you can see from this slot machine screenshot, the background has been replaced with a new bonus background while the bonus feature is played.
The prize potential during the 20 free spins is quite amazing because the slot machine is played with all prizes doubled. This also include prizes from scatter bonuses and combinations with wild symbols as shown in this Congo Bongo screenshot. The Congo Bongo free spin bonus feature is played with the same amount of active paylines as the player did when the bonus feature was triggered. This means that players can win on multiple paylines during each of the free spins if several paylines were active when the feature was triggered.
