Bow tie antenna are widely used because their exhibit a very low profile, small size, light weight, low cost, high efficiency and easy methods of fabrication and installation. This actractive rugged bow tie antenna design exhibits wide bandwidth and good radiation characterictis. Omni-directional antenna invented here have 65-89% efficiency with peak gain value is 3.8 dBi. and covers the 5 cellular bands. In general, the antenna is about 1.5 inches high, 5 inches in diameter, and built with a standard TNC male connector at the other end. The antenna will operate within any of the cellular bands between 806 MHz 960 MHz and 1710 MHz 2170 MHz, and should be built to operate in an outdoor environment. This antenna is for a low profile outdoor rugged antenna to be in typical outdoor applications such as ATM machines and vehicle installations.
The novelty comes from the antenna design, which is miniature for outdoor application and produce a linear, vertical polarization while the azimuth plane, (Horizontal) -3dB Beamwidth is omnidirectional. Out of the ordinary, the antenna was able to perform with great efficiency and obtain size reduction without ignoring bandwidth and gain.
This antenna is for a low profile outdoor rugged antenna to be in typical outdoor applications such as ATM machines and vehicle installations and will operate within any of the cellular bands between 806 MHz 960 MHz and 1710 MHz 2170 MHz.
