AbstractA broadband circularly polarized slotted square patch antenna with horizontal meandered strip (HMS) is presented and studied. The HMS feeding technique provides the good impedance matching and broadside symmetrical radiation patterns. A set of cross asymmetrical slots are etched on the radiating patch to realize the circular polarization. An electrically small stub is added on the edge of the antenna for further improvement in performance. Measured 10-dB impedance bandwidth (IBW) and 3-dB axial ratio bandwidth (ARBW) of the proposed antenna are 32.31 % (3.14–4.35 GHz) and 20.91 % (3.34–4.12 GHz), respectively. The gain of the antenna is varied from 3.5 to 4.86dBi within 3-dB ARBW. Measured results matched well with the simulated results.

Microstrip Patch

In this paper, a simple mail box design of a dual band microstrip patch antenna, is proposed, designed, fabricated and measured for wireless LAN communications. The proposed antenna is designed using the TLC 30 (TACONIC) substrate, with a relative permittivity of 4.3 and substrate height of 1.6mm. It is designed to operate at 2.44 GHz and 5. 30 GHz respectively. The proposed antenna is the size of 31mm x 34mm x1.6mm and is incited by a 50 Ω micro strip feed line. The characteristics of the antenna are designed and the performance of the modelled antenna is evaluated using CST Microwave Studio. The return loss, radiation patterns and peak antenna gain of 6.5 dBi for frequency 2.44 GHz and 6.2 dBi for 5.30 GHz is separately and successfully plotted. The fabricated prototype exhibits an agreement between the measured and simulated return loss.

Stacked Patch Antenna

A Double Frequency stacked patch antenna array, DESIGNED for the frequencies of 1.348 GHz and 1.575 GHz in L-Band . The array accommodates sixteen antenna elements of 4×4 array fed by individualistic coaxial cable. The Radiation patterns for the two single element and array are studied. Comparison between the radiation patterns of a specific element and array are studied. Dual patch is used for both single element and antenna array, two patches resonates for two different designed frequencies of L-Band the impedance characteristics of both single element and array are studied and gains of single element and array are compared. ANSYS HFSS software is used for the simulation in this proposed work.

Operating Bandwidth

A compact patch antenna with stacked parasitic strips (SPSs) based on low temperature cofired ceramic (LTCC) technology is presented. By adding three pairs of SPSs above the traditional patch antenna, multiple resonant modes are excited to broaden the bandwidth. At the same time, the SPSs act as directors to guide the antenna radiation toward broadside direction to enhance the gain. The measured results show that the prototype antenna achieves an impedance bandwidth of 16% forS11<-10 dB (32.1–37.9 GHz) and a maximum gain of about 8 dBi at 35 GHz. Furthermore, the radiation patterns and gain are relatively stable within the operating bandwidth. The total volume of the antenna is only 8 × 8 × 1.1 mm3.
