[0003] Microstrip antenna, as a new type of antenna with considerable application potential, can well meet the requirements of miniaturization, multi-band and ultra-wideband. At the same time, considering some special performance requirements and installation environment restrictions in practical applications, Traditional rectangular and circular patch microstrip antennas can no longer meet the needs. Therefore, it is particularly important to study microstrip antennas with different shapes of radiating patches and to design microstrip antennas suitable for different applications. urgent and meaningful

Abstract
The invention discloses a three-frequency-band microstrip antenna for WiFi, WiMAX and WLAN. The antenna comprises a base plate, a radiation patch []and trapezoidal grooves, wherein the radiation patchis arranged on the upper surface of the base plate; the radiation patch is of a rectangular structure; a pair of trapezoidal grooves are formed in the middle of the rectangular structure; a pair of short rectangular grooves and two pairs of long rectangular grooves are formed in the two sides of the trapezoidal groove; a pair of rectangular grooves are formed in the lower side of the trapezoidalgrooves. The antenna has the advantages of good radiation performance, multiple frequency bands, high gain, simple structure, small dimension, easy manufacturing, convenient integration and the like.
Description
technical field [0001] The invention relates to an antenna, in particular to a microstrip antenna for WiFi, WiMAX and WLAN three-bands. Background technique [0002] After more than 150 years of development, wireless communication technology has been widely and deeply affecting people's daily life. At present, the number of wireless communication customers in the world has already exceeded 100 million, and it is growing at the rate of hundreds of thousands of people every day. While enjoying the various conveniences brought by wireless communication technology, people also put forward higher requirements for various wireless communication devices, the most important of which is miniaturization and multi-function. Therefore, the design of the antenna, which is one of the main components of the wireless communication equipment, has brought severe challenges. The miniaturized multi-frequency antenna is to integrate multiple communication standards into a compact antenna, whic...
