Effective magnetic loop array antenna with enhanced bandwidth

An effective magnetic loop array antenna with modified feeding structure is designed, fabricated and tested. This antenna works at 4.83 GHz-5.04 GHz, and radiate omnidirectionally in the azimuth plane. Compared with the original effective magnetic loop array antenna, the bandwidth increases 3 times. The average gain is 5.65 dB, and the elevation angles at different frequencies are about 30 degrees. This antenna is low profile and of compact structure, which is easy to be conformal to other surfaces.
