An electrically small meandered line antenna with truncated ground plane
An electrically small meandered microstrip line antenna was investigated. The antenna was designed, fabricated and measured for an operating frequency of 2.4 GHz with a 10 dB return loss bandwidth of 2%. In order to improve the efficiency and gain, a truncated ground plane was used, and its effect on balancing the antenna currents has been studied. A Wheeler Cap was designed for the efficiency measurement and the 3-antenna method was used for measuring the gain. Ka of this antenna is 0.26, it has a gain of −0.86 dB and an efficiency of 49.7%, making it one of the efficient and high gain small antennas.
