“…At a given operating frequency, lower dielectric constant of the substrate leads to larger bandwidth and larger size. From Table 4, it can be noticed that the dimensions and volume of the proposed Antenna-I and Antenna-II are much smaller than those presented in [1][2][3][4][5][6][7][8][9][10][11][12][13][14], but slightly larger than that in [21]. The listed dimensions in [21] are those of the printed patch and the dimensions of the ground plane are not given in [21] but they are obviously larger.…”

“…The obtained results of the proposed Antenna-I and Antenna-II are compared with those of the antennas presented in [1][2][3][4][5][6][7][8][9][10][11], [14][15][16], [21]. The comparison takes into consideration the total substrate dimensions and the volume of the antenna, frequency range, bandwidth, gain, as shown in Table 4.…”

“…The radiating element is a circular patch with a cross-slot and a ring-slot to excite the TM 11 mode at the GPS L 1 and L 2 bands, and the measured bandwidths were 6.1% and 3.7% respectively. A novel feeding system for microstrip radiators which is based on an electromagnetic coupling was presented in [10]. The single feed line is ended by two arms which hug the patch near the edge in a symmetrical manner with a capacitive gap to the two adjacent sides of the rectangular patch in order to initiate circular polarization.…”

This paper presents a new wideband microstrip circular patch antenna (MCPA) fed by proximity-coupled line with double-stub matching to achieve dual-band operation. Bandwidth extension is achieved by exciting higherorder modes in the circular radiating patch, and using two stubs to achieve adequate matching across the obtained two bands. The characteristics of the antenna such as reflection coefficient, impedance bandwidth, gain and radiation pattern are investigated and optimized through parametric studies using the CST Microwave Studio Suite. The antenna achieved a large relative bandwidth of 45.16% at the upper band, while the lower one has 10.3% relative bandwidth. The maximum achieved gain of the dual-band antenna in the 5.8GHz band is 4.62dBi while it is 4.85dBi in the upper band. The antenna has an overall size of 30×30×3.2mm3 corresponding to 0.58λ × 0.58 λ × 0.062 λ at the lower band of 5.8 GHz. The proposed antenna should be useful for WLAN and X-band communication systems.

“…In [168], a low profile dual-band antenna for indoor/outdoor wearable applications is proposed. This antenna achieves about 63.86% size reduction related to a convention CP slotted patch antenna [169], and about 15% as compared to other electromagnetically coupled CP antenna designs [170, 171]. This antenna [168] uses a CSRR for size reduction and also to enable CP properties in the lower band.…”

Microstrip radiators with Circular Polarization (CP) are paid much attention in wireless and navigational applications. In this paper, four microstrip rectangular radiators with axially centered asymmetric Triangular-Semi Elliptic (TSE) slots along the square boundary of the patch are proposed. The probe feed is applied along the diagonal of the square patch and it is optimized for its position to get CP radiation. 50 mm  50 mm. The scale down versions of ASP#2 presented are ASP#3 (40 mm  40 mm) and ASP#4 (30 mm  30 mm) suitable to operate in IEEE 802.11y(3.65-3.7 GHz) and 802.11a (5.2 GHz) Wi-Fi applications with CP radiation. The proposed ASP#3 offers 10dB RL bandwidth of 390 MHz, 3dB AR bandwidth of 100 MHz and a peak gain of 4.3 dBi with CP. ASP# 4 offers 10dB RL bandwidth of 590 MHz, 3dB AR bandwidth of 160 MHz and a peak gain of 3.95 dBi with CP. It is evident from the results the proposed ASP#1 and ASP#2 are suitable for WLAN (2.4 GHz) and GHz) band applications. All the proposed four antennas are fabricated; measured results are compared with the simulation results.
