This paper presented a patch circular polarized antenna for GSM technology at 1.8 GHz and WLAN technology at 2.4 GHz. A traveling wave microstrip array antenna consisting of square truncated patch operated as circular polarized has been designed, fabricated and measured. The inter element spacing; length and width of the square and circular patches of the array antenna were optimized by successive simulations using the CST software. This antenna had radiated at 1.8 and 2.4 GHz of resonant frequency with −38.563 and −24.967 dB of return loss respectively. The axial ratio for RHS circular polarized is 0.95 < 3 dB at 2.4 GHz.

“…Other characteristics consisted of a copper thickness of 0.035 mm, substrate dielectric constant (ε r ) of 2.2 and tangent loss (tan δ) equaling 0.019. Two symmetric truncated corners (4.2 × 4.2 mm) on a metal radiator patch cause the antenna to radiate in circular polarity as demonstrated in [21]. The dimensions and the characteristics of the antenna are represented in Figure 2.…”

Abstract-In this paper, a channel characterization of an RF link using circularly polarized antennas inside a mine is performed. The association of circular polarization with multiple-input-multiple-output (MIMO) radio technologies represents a powerful tool to improve the performance of an underground RF channel. The statistical parameters of the channel are derived from in-mine measurements at the 2.4 GHz band for both co-polarization (CP) and cross-polarization (XP) scenarios. Results show a remarkable improvement through the use of MIMO combined with circular polarization compared to the regular patch MIMO antenna system, in terms of channel capacity and path loss. This improvement increases significantly at the XP scenarios, reaching up to 18 bps/Hz for channel capacity and up to 21 dB for path loss. The RMS delay spread for a circularly polarized setup is generally higher than the linearly polarized MIMO patch setup due to surface roughness of the gallery. In the linear polarization case, a signal degradation of more than 15 dB at the XP case is observed compared to the CP scenario. This signal loss that is due to depolarization is somewhat mitigated by the surface roughness. Due to its superior and stable performance, MIMO combined with circular polarization is better suited than a regular MIMO patch system for in-mine uses especially in the applications where the transmitter may change direction with respect to the receiver.

In this paper, a broadband circular polarized antenna with operating frequency at 2.4GHz is proposed. The antennas are designed by using L-probe amendment with inverted patch by using suspended rectangular microstrip antenna (MSA) technique to improve the bandwidth until more than 200MHz. The characteristics of the antenna are analyzed, so that the antenna meets broadband operations at operating frequency of 2.4GHz with return loss less than -10dB. The broadband circular polarized antenna had been designed and simulated by using Computer Simulation Technology (CST) software.
