“…Based on the above results, we compared performances of the PLPTDA antenna with its counterpart antennas in the literature; in terms of antenna size, bandwidth ratio and antenna gain (Table 1). Thus, the bandwidth of the proposed antenna is broader than those in [4–6, 11–14, 16–18, 20, 21, 23, 24] and the measured gain of the PLPTDA antenna is higher than in [4, 6, 7, 11–21, 23, 24]. Although the proposed antenna bandwidth is 1:9 same as the antenna in [15], they aimed to increase the antenna gain at WLAN (2.45 and 5.27 GHz) frequencies.…”
