Abstract:

A reactive impedance surface (RIS) based miniaturized bent slotted patch antenna is proposed and investigated for S-band applications around 2.39 GHz. Bent slots in the patch reduce the patch antenna size by increasing current path on the patch. Further a RIS substrate with cross-shaped patch elements printed over a grounded dielectric is optimized and investigated for antenna miniaturization. The proposed bent slotted patch antenna over RIS substrate is 38.75% miniaturized with respect to traditional patch antenna at a fixed operating frequency.

In this paper a slotted microstrip patch antenna has been designed that works for two frequencies 1.42GHz and 2.65GHz. Since a microstrip patch antenna works only on one resonant frequency so converting that into a multiband patch antenna would enhance the bandwidth and also utilizes the multiple frequencies of operation. This multiband slotted patch antenna is fabricated on FR4 lossy dielectric substrate whose dielectric constant is 4.3 and height is 1.6mm. The length and width of patch are taken as 51.16mm and 39.86mm respectively. we cut out the slots so that the patch antenna works at mult

Abstract:

Abstract A single feed compact novel slotted circular patch antenna for operating in 3.5 GHz mobile WiMAX applications is presented in this paper. The proposed antenna is designed using low cost FR4 substrate and copper material. The proposed antenna has the lowest dimension of 20×30 ×1.6 mm3. The proposed antenna is simulated in CST Microwave Studio. The proposed antenna resonates at 3.5 GHz resonant frequency with the bandwidth of 350 MHz and return loss of - 32 dB. The proposed antenna achieved the peak gain of 5.36 dBi. along with the efficiency of 96 %. The proposed single feed compact no

Abstract:

In this paper a new geometry of circularly polarized patch antenna is proposed with improved bandwidth. The radiation performance of proposed patch antenna is investigated using IE3D simulation software and its performance is compared with that of conventional rectangular patch antenna. The simulated return loss, axial ratio and impedance with frequency for the proposed antenna are reported in this paper. It is shown that by selecting suitable ground-plane dimensions, air gap and location of the slots, the impedance bandwidth can be enhanced upto 10.15% as compared to conventional rectangular

Abstract:

A hexagonal patch antenna with a Swastik slotted design on radiating patch and integration of metamaterial-based Complementary Split Ring Resonator (CSRR) is proposed. The Swastik slot is designed with equal and un-equal arm lengths. Swastik slot with equal arms yields a better result compared to unequal arms. Swastik slot with equal arms results in a bandwidth of 8GHz(12 - 20GHz) with a peak gain of 6.1dBi. For further performance enhancement, the proposed antenna is integrated with metamaterial-based CSRR’s. Integration with metamaterial-based 4´4 CSRR’s results in a bandwidth of 11.78GHz (8
