Abstract :
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.
