CPW-Fed Circularly Polarized Slot ANTENNA with Elliptical-Shaped Patch for UWB Applications

A new design of coplanar waveguide (CPW)-fed antenna with circular polarization (CP) and excellent impedance matching is presented. In this design a pair of circular-shaped slits is applied to opposite corners of the slot for enhancing the impedance matching and realizes bandwidth of 134.43% across 2.98-15.20 GHz for VSWR≤2. Furthermore this structure exhibits axial ration bandwidth (ARBW) of 3...

Circularly Polarized Patch Antenna With Enhanced Band Width & Gain

In this paper, one 5 × 5 antenna array are studied. In each array, one probe-fed circularly polarized (CP) microstrip patch antenna is placed at the center as the driven antenna and is gapped coupled to the remaining elements. It is investigated that CP performance of the patch can be proved by properly arranging these parasitic elements. The driven patch is a perturbed square one with two diag...

Circularly Polarized Patch Array Antenna with Enhanced Isolation Characteristic

The design of an integrated rectangular microstrip patch array antenna with enhanced isolation characteristic between transmitter and receiver is presented to produce a full-duplex transceiver with transmit and receive operation at the same frequency and with the same polarization. This integrated circulator-like antenna has potential uses in both short-range communication systems and radar.

Optimized Circularly Polarized Bandwidth for Microstrip Antenna

In very high frequency performances such as spacecraft, satellite & missile applications where the size, weight, cost, performance, ease of installation & aerodynamic profile are constraints microstrip antennas (MA) are used to meet these requirements. In spite of limitations such as small bandwidth, low gain and low power handling capability, microstrip antenna offers good performance over oth...
