In this paper, we have presented an equation for estimating the gain of a Fabry-Perot cavity (FPC) antenna with a finite dimension. When an FPC antenna has an infinite dimension and its height is half of a wavelength, the maximum gain of that FPC antenna can be obtained theoretically. If the FPC antenna does not have a dimension sufficient for multiple reflections between a partially reflective surface (PRS) and the ground, its gain must be less than that of an FPC antenna that has an infinite dimension. In addition, the gain of an FPC antenna increases as the dimension of a PRS increases and becomes saturated from a specific dimension. The specific dimension where the gain starts to saturate also gets larger as the reflection magnitude of the PRS becomes closer to one. Thus, it would be convenient to have a gain equation when considering the dimension of an FPC antenna in order to estimate the exact gain of the FPC antenna with a specific dimension. A gain versus the dimension of the FPC antenna for various reflection magnitudes of PRS has been simulated, and the modified gain equation is produced through the curve fitting of the full-wave simulation results. The resulting empirical gain equation of an FPC antenna whose PRS dimension is larger than 1.50 has been obtained.

“…It is worth mentioning that in radar applications, through utilizing CP antenna the weather clutter can be suppressed, leading to the performance improvement of the system in target detection. Aperture coupling is utilized for feeding the MPA because of having low level of cross polarization [20]. This subject is very important in the design of the monopulse tracking radars in which the error of target tracking can be reduced [21].…”

Abstract-In this paper a compact wideband aperture coupled microstrip patch antenna (MPA) with impedance bandwidth of 26.3% is designed. Size reduction of the radiating element and the slot in the ground plane is achieved by incorporating an interdigital capacitor (IDC) in the patch and a complementary split ring resonator (CSRR) close to the slot which offers composite right/left-hand (CRLH) antenna. An interdigital capacitor in the patch acts as series left-hand component, and the slot together with the CSRR in the ground plane acts as a left-hand parallel inductor. By this technique, the patch and slot dimensions compared with the initial designed antenna are reduced about 26.2% and 30.2%, respectively. Through cutting CSRRs with different arrangements in the ground plane, a dual frequency band antenna is designed. Finally, a compact wideband circularly-polarized (CP) MPA is proposed through imposing various perturbations in the current route in the ground plane of the antenna. The maximum gain and the impedance bandwidth of the designed CP antenna are 8.4 dBi and 25%, respectively. Two designed antennas are fabricated and tested. The measurement results confirm the simulation ones.

“…However, they also suffer from unexpected feed radiation, narrow impedance bandwidth, higher cross polarization which needs to improve by using efficient designing techniques of the antennas [1,2]. The recent literatures suggest adding extra resonators [3], using meandered strips [4], applying aperture coupled feed [5], employing thick dielectric substrate [6], modifying the ground plane [7] and so forth.…”

Abstract. In this article, a simple design of rectangular microstrip feed planar antenna with wide arcs and square shape slot is proposed for Radio Frequency Identification (RFID), Worldwide Interoperability for Microwave Access (WiMAX) and C/X-band wireless communications. The prototype of the antenna has been fabricated 1.0 mm thick ceramic filled bioplastic substrate by using optimal dimension obtained from design/simulations and antenna performances are experimentally tested. The experimental results confirm the impedance bandwidths for S11≤ −10 dB are of 712 MHz (0.355-1.067 GHz), 1.38 GHz (2.92-4.3 GHz) and 2.46 GHz (6.55-9.01 GHz) for 0.788, 3.34 and 8.01 GHz band respectively. The proposed antenna shows almost steady and symmetrical radiation patterns for all three bands with the maximum gains of 1.37, 2.8 and 3.56 dBi respectively. Based on the antenna performances, it can successfully cover the frequency band requirement for RFID, WiMAX and C/X-band applications.
