How to increase gain of slot antenna

networks have a range that's limited by the frequency, transmission power, antenna type, the location they're used in, and the environment. [1] A typical wireless router in an indoor point-to-multipoint arrangement using 802.11n and a stock … US6646618B2 - Low-profile slot antenna for vehicular

Since the array must consist of many small antennas (sometimes thousands) to achieve high gain, phased arrays are mainly practical at the high frequency end of the radio spectrum, in the UHF and microwave bands, in which the antenna … Cantenna - Wikipedia Cantennas are typically used to increase the range (or discovery) of Wi-Fi networks.

In this paper a printed micro strip line fed wide slot antenna is presented. A slotted parasitic patch is introduced to improve the gain along with the bandwidth. For bandwidth improvement a slotted technique is used in ground of the antenna along with rotation in patch and a simple 50 ? microstrip line fed is used to excite the slot in the ...

What are techniques to increase the bandwidth of ... Microstrip antenna has various applications because it have various advantages as to conventional antenna.But the biggest disadvantages is that it has very narrow bandwidth and low gain.and these are the subject for new research as well the requirement of antenna of small size for various mobile and other applications. How can I increase the gain of a CPW fed slot antenna? The antenna is a spiral slot fed by a CPW. It has good impedance matching but its gain is 0 dBi. Slot Antenna If we can excite some reasonable fields in the slot (often called the aperture), we have a slot antenna. Figure 1. Rectangular Slot antenna with dimensions a and b. To gain an intuition about slot antennas, first we'll learn Babinet's principle (put into antenna terms by H. G. Booker in 1946).

Some other rubber ducky antennas use a spring of non-conducting material for support and comprise a collinear array antenna.

... due to curving the antenna is an increased cross-polarization in the E-plane. ... pattern characteristics with moderate gain of approximately 8. dBi [I]. The fmt ...

High-gain antennas have various applications such as in satellite platforms, radar systems, routers, and repeater systems. A number of enhancement techniques for antenna gain have been studied –. To realize enhanced-gain performance, a cavity-backed slot antenna (CBSA) is employed in this study because of its unidirectional characteristic.
